WoW!!! The Axiom II is beyond amazing, I am fully satisfied. The sense of 'live' was greatly enhanced in my system, low noise, airy, the Axiom II lead to considerable system synergy. It made a night a day difference and when compared to other preamps costing thousands of dollars more it still comes up on top. I just wish I bought the Axiom II years ago.
The unit arrived on Saturday, today. I am running out for the day but could not resist and unpacked the unit and sat and listened to a few songs. After only listening to a couple songs from a few CDs I believe you have done the magic I was hoping for. The upper end has opened up allowing more detail and space to come through without adding any harshness. I am sure as the unit breaks in this will get better and better. Once I have some time to really sit and listen I will let you know my full opinion on all the improvements.
The packaging and workmanship is fantastic. It is obvious that you take extreme pride in your work and it shows.
Until your pre arrived I had used a simple British built passive pre with ALPs pot.
I listen to a lot of dance music and hip hop, despite my advanced age and bass timing, quality and the ability to track rhythms through the mix are very important. The passive pre I used lacked some depth and engagement.
As soon as I dropped the Axiom II into the system the sound quality moved to another level. I'm sure it will take some burning in but even straight out of the box the sound quality far exceeded that of the pre I had been using. Before the Micromega I had used a very expensive DAC/Pre, the Prism Sound Orpheus. The quality of your pre and the simple Micromega easily beats the much more expensive unit.
The soundstage is very wide, bass is really rich and the monitors have never sounded as good, with the Berylium tweeter sweet and accurate.
I think the Axiom II is amazing quality and incredible value. I can't see why someone would go back to a powered pre if they heard this product. I can of course see the day when I ask you to upgrade the current Sig spec to higher but for now I am extremely happy with my choice.
Many thanks and kind regards,
Anyway, I just wanted you to know that the sound quality of this unit
completely blows away a Goldpoint passive that I purchased a few years ago.
It's not even close. You can quote me. And, the sound is as close to tubes
as any non-tube preamp I've listened to. That's pretty shocking. My wife
will tell you that I have too many tube preamps. With a good tube preamp,
smooth jazz, especially vocals and guitar, sound better than anything.
However, rock, techno, complex new age and some classical sounds better with
solid state. With my current Axiom, it's the best compromise there is.
Upon receipt of my Axiom pair XLR (walker mod. version), I was immediately struck by the care with which the packaging was done. I opened the outer box, then the individual inner boxes. I appreciate a minimalist design devoted purely to sonics, and that is exactly what the Axiom delivered. "Straight wire with gain" only, an audiophile's delight. I connected the units to my system. After careful calibration of each channel's gain , I engaged the signal source. POW !!!!! to my utter, total, and complete amazement, my former sound stage was deeper, wider, taller and cleaner than It had ever been before !!!! I have been in and around high end audio gear for the better part of 20 years. If you can name the manufacturer, I have probably auditioned or owned the product. However, I have never encountered a product that yields greater musicality at a fair price in my life. The "fit and finish" is first rate. The attenuator is silky smooth. Please keep doing what you do. This is a product that I can continue to enjoy, and grow into for many years to come. Tim, my sincere thanks and appreciation to you and your staff.
I just wanted to tell you that I received the AXIOM today, beautifully packaged I must say!
How can I say 'Thanks for nothing' without you taking offence? That's to say all I can hear is the rest of my system and, for the first time!
Nice, nice, nice!
All the best from France and thanks again for all your help and patience!
Just received the Axiom. You guys are fast.
Short response: Stunning. Look for my old preamp on Audiogon in the next few days!
My source is a McIntosh deck, now plugged into the Axiom, which in turn feeds two 500w Mc monoblocks. Speakers are Piega P10s (ribbon/cone hybrids); all fed with pristine, dedicated juice and connected via Shunyata cables.
I thought the old unit was doing a splendid job (even though the pots were getting a little noisy when worked - par for the course after 8 years, I suppose). But the Axiom takes the setup to a wholly different level. Clean. Dead silent. Holographic. I just played Burmester's demo CD (my favorite test tool). Bloody hell.
I thought my next upgrade might be a good DAC (even though the Mc's is superb), but the way things sound now I really can't imagine how it could get any better. (My opinion isn't exactly baseless; I've been an audiophile for over 40 years and owned some pretty exotic gear in the past.) Well, as much as I love my Piega's, the Axiom's now given me the upgrade bug; perhaps I'll move the Piegas upstairs and invest in a pair of new Quads or Harbeths. I suspect that'll set me squarely in audio Nirvana for the rest of my days.
If people would only stop buying into the marketing hype, learn to listen with their own ears and give the Axiom a try, the ensuing stampede could cause deep disquiet in many a high-end house. I'm now convinced a passive pre is the only way to fly (the Axiom's my first, by the way; thought I'd give one a try while I sent my unit in for service; a no-brainer at $150). This is about as close to the ideal of a straight wire-with-gain as one is likely to get. With levels matched to within 0.1dB, I dare any golden-eared expert out there to distinguish between your unit and ANY high-end pre in an honest ABX double-blind test. I know I wouldn't be able to tell the difference.
Thank you for a superlative product.
Tim,I've had my Axiom for about a week now and all I can say is holy s***.This tiny little box is just amazing.
It is much more than I could have wished for.Detail,space,
everything that I should hear is there.Quality recordings
shine,and it is very revealing of poorly recorded cd's.
I give this unit my highest praise.
Dear Tim thank you very much for the Axiom pre amp you sent me, I am definitely very impressed and believe it to be one of those unusual hi-fi finds that is a good honest piece of equipment.
It does what it is meant to do at a great price and without the usually marketing hype. You got the settings just right for my system and I was very surprised by how loud it makes my speakers with only a modest amount of input.
It is as close to not having anything in the signal path as I can find and I am delighted. It also helped tremendously with my weak bass problem, I would say I am hearing a more balanced version of the music than I did with my previous pre amp.
Please feel free to use this email as a recommendation for this product any way you see fit.
Best wishes, Geoff
Got it today! I am slackjawed... amazed! Opened up the soundstage and defines the individual instruments... SUPERB PRODUCT! Thanks!!!
Axiom arrived today.
Plugged it into $6000 worth of Naim NAP 135 monoblocks ( Naim, incidentally advise against using any form of passive preamp )
And it is really stunning.
Quiet quiesant background ( no hum or hiss of any form )
Detailed and as far as I can hear ... excellent.
I am impressed, well done.
I received the preamp in good condition on Friday and hooked it up that
Wow !! What a sound, it was marvelous to hear I could further increase
everything one notch !! Definition, space, information, soundstage,
transients, zero noise and especially more precision everywhere...
How can you beat my "brand X" ???
I am VERY happy ! It seems that the Axiom lets more energy of medium to
high frequencies go through.
Very well done !
Thanks again for the unexpected satisfaction ;-))
The Axiom is AMAZING!!!...Thanks! Bob
I received the unit yesterday and just hooked it up. It is a tremendous
value! (but I guess that is no news to you!) It sounds even better since
my preamp has been out for repairs for 6 weeks. Thanks
...The product is fabulous and I will be leaving positive feedback on
Audioreview if your product is listed there. I will definitely be spreading
the word around here. Congratulations on a simple but great design. The
Axiom is truly transparent and I have never heard my system sound so
natural. You can quote me on this!
I will never go back to active preamps.
I received the Axiom Passive Preamp today in perfect condition. The Axiom sounds better than I expected. The bass is tight, mids are transparent and highs are clear without becoming abrasive. I guess the word I would use to define the sound using the Axiom would be "PURE". Best audio purchase I've made in a long while.
Nice go-in on this Axiom passive pre..Well you were right about one thing,,, THE LOW END REGISTER IS FABULOUS.. But the top end is also very open and special indeed...This piece is a great addition to my system..Thank you for your time in engineering it, and offering it to the Audio Community!! Stay on track and keep it simple.Your applied idea's are a breath of fresh air, in this already poluted business.
I got it. It works so well. I can hear what I've been missing. Thanks for the great product. Now I have to figure out what I do with my useless preamp.
I wanted to let you know I received the preamp on Tues and have been listening for the last two nights. It does live up to all you said. I purchased it as a stopgap while my "brand X" went in for repairs. I am going to be listening all weekend but I am now seriously thinking of substituting it permanently . Only my turtle-like typing speed prevents a page or so of accolades. I am more than satisfied. Please feel free to use me as a reference.
Tim, I wanted to give you a quick follow up to my recent Axiom purchase.
First I sold my tube preamp yesterday. The Axiom sounds that good and I
have about $900 dollars in my pocket. There is more bass now than
before and this is welcome as I use LS3/5a monitors. Second I hear a
little more resolution than before. It is not as smooth as with the
tube preamp but it is clearly more representative of what my cd player
is putting out. I use a Sony DVD/SACD which is biased towards
resolution rather than sweetness.
Second, everyone says that passive are less dynamic. I have not found
this to be the case. Furthermore, I do not have to turn the music up
louder to appreciate it. Actually, the reverse is true because of the
extra bass I have now.
Thanks for the little Axiom.
I got the Axiom passive pre-amp. My initial reaction is it is super clean. I was running a Theta Miles direct into a Bel Canto Amp; the gain into the amp is just right now. I also lost no clarity by putting the pre-amp in between the player and the amp. I picked up mucho, cleaner, deeper bass and lots more mid-range and tweeter detail... Feel free to use my comments as you see fit.
Thanks for keeping clean and simple,
I've been listening to my few favourite CDs I brought here for the last couple of hours, and now I'm thinking of taking the "brand X" preamp back to Germany and sell the bugger, and order another Axiom from you when I'm back to NY.
Nice to see that upgrading doesn't necessarily mean spending MORE money ... ;)
It 'sounds' to me like your interconnects, meaning that it does nothing at all to the signal, as far as that is possible.
Which is about as good as it gets for cables or passive preamps, imho.
I really have to try some of your speaker cables next time I'm here, I guess...
The Axiom finally arrived today! Bit of a wait, but I have to say I'm more than a little impressed! I originally bought it to use with my Leak Stereo 20 and you set the axiom up accordingly, but my ST20 has since developed a fault so I tried it out with a pair of Quad II's I also have. The Quad II's are reputed to prefer active preamps so I wasn't expecting great things....but that's exactly what I got - crystal clear, dynamic, stacks of bass, just fantastic. I'll recommend your little preamp to anyone who'll listen.
The preamp was tested and the result was outstanding.
The challenge was not an easy task. Stock units were: "brand X" and "brand X" as active preamps and the "brand X" in passive option.
The Luminous was the most real of them all no contest. Of course when
gutsier bass were needed since my power amps are all 300b's based the active
units were better, the dynamics were a bit better on the active units as
well but not by a wide margin. The low level data was better with the AXIOM
and when I wanted to listen to music , JUST LISTEN TO IT , the best was this
little giant. Congratualtions for a great product Tim!
Sincerely . Victor.
I know you hear this a lot, but I just have to tell ya that this little
black box is really fantastic. The difference was like night and day. This
thing makes the music breathe with an incredible sense of depth and clarity!
I mean, WOW!
Just to give you an idea. I had previously grouped up my CD's... splitting
them up between those that sound like crap, and those that sound good. I
thought lame mastering was to blame for the "bad" ones, and on some discs
I'm sure this is the case. But overall, this little box is so musical that
it has brought the "bad" CD's out into circulation once more. It has truely
made my CD collection whole again.
Thank you so much,
I received the preamp today. I compared with my 'brand x' this night, and I found your Axiom preamp is better that my 'brand x'.
It is really great sound.
Thank you very much !
Very best regards from Hong Kong,
Just to let You know: Even in the frostcold North, In Finland, Axiom allows the music run untouched through. Ashtonishing clarity and tonal accuraty! Dead quiet backgrounds and fine dynamics. What else can man ask for?
I received the axiom today and hooked it up. It works perfectly, and its
damn nice to own an audio equipment that sounds great, doesn't weigh a ton
and is inexpensive! :)) I'm way over the moon with this purchase! The wait
has been well worth it!
I received the pre-amp this weekend. It's truly transparent in my system, it produces no hum at all. I would say your pre-amp sounds great, but the truth be told is that I can't hear it.
I'm now able to run my amps at full power, and am getting a much cleaner sound.
Thanks for providing such a great product.
Got the preamp yesterday, and have just left you feedback. Please do the same when you have a chance.
The preamp has made the greatest improvement in my system of any component I can remember. I thought I had a pretty good hybrid tube pre, but wow! yours just blew it away. Not only is the system now dead quite between pieces of music, but it's as though a veil has been lifted [especially from the bass]: dramatically better imaging and soundstage, and virtually perfect presentation of the music, note for note, top to bottom, wonderful delineation of every instrument and voice. I could go on and on, and will probably enjoy it even more as time goes by: after all, I've only had it only one day!
Received the Axiom yesterday and listened well into the night. It is an outstanding product with very good resolution and dynamics. But the transparency is really impressive, easily the best I have heard in a preamp at any price.
Thanks Tim, I just love the passive pre, it's an absolutely fine piece of gear. I really appreciate it. By the way, your passive pre is just world class. Steve
I received the Axiom preamp today and began auditioning the Axiom preamp. All I have to say is WOW!!!! I am listening to my John Hick's piano jazz albums all over again!!! The soundstage opened up dramatically (vs. my old preamp). John Patatucci's bass sounds so organic it is coming straight at me I can feel it in my chest! All with no equalization or enhancement, the signal fed directly through the Axiom's resistor.
Thanks again, Sam
Tim, I received the Axiom, and it arrived in excellent shape. Many thanks!
Congratulations on coming up with such a phenomenal product!
The unit greatly opened up the sound stage, providing excellent delivery on the entire spectrum. It is without a doubt superior to my active pre-amp, with a strikingly transparent and dynamic sound that I had not anticipated.
Tim: I got my preamp. I've been dabling in audio stuff for over 35 years. Very rarely do you plug something in and it changes everything. Your preamp is such a piece. Now it is an odd set up I've put together for my son--the McCormick, the vintage Allison, and an Ipod feed, but it is still quite amazing. The clarity is astounding, the SN is unlike anything I've ever heard, and the purity of the sound is terrific. Thanks so much.
Hi, Tim !
Two years ago I happily purchased one of your Axioms. Very nice, too.
For the last couple of years I've been messing about with all sorts of pre-amps....passives, actives, valves, transistors....you name it. All sorts of "pots". And then I remembered your pre. So I plug it my system and WOW. I'd forgotten just how good it was. Great clarity, tremendous bass (no need for a sub), very wide soundstage, great dynamics. Really shows up how compromised most pre-amps are. All this you know !!
I recieved the pre amps this morning and everything is working perfectly and it is an incredible improvement on my $3,900 pre amp. Congratulations on a superb product and I hope to get you some orders from my friends in the future.
All the very best Jim C.
Rec'd the axiom. Fantastic, better than I expected. Probably the best buy in audio today.
I received the Axiom preamp yesterday.
First off, let me thank you for the marvelous service and quick fulfillment of the order.
Secondly, thanks for the tremendous product. My criteria for good audio equipment is transparency and this little jewel delivers it in spades. It's an incredible value Tim. You are to be commended!
Tim, I finally received the pre and connected it to my two Naim NAP 135 Amps
(driving a pair of Cabbase Iroise cabinets). I'm absolutely satisfied and pleased with the result.
Great product and definitely worth the money!
The **** preamp plus the necessary power supply I used originally did cost about 5500,- Euro.
For Axiom Pre I had to pay around 130,- Euro.
That's what I call competitive ;-)
The Axiom arrived today - it works perfectly, excellent attenuation with no loss of fidelity. My bedroom system (Squeezebox + ZVex iMPaMP) just got a lot better. I was losing a lot when lowering the volume with the Squeezebox - not anymore.
Thanks again for your speedy service!
The Walker Mod XLR Axioms arrived today and I have hooked them up... I am gobsmacked! ... WOW! ... Straight out of the box they sound fantastic without even being broken in yet. I am actually hearing more details, layering, bigger, wider, taller and more 3D holographic soundstage with deeper bass, more natural vocals and instruments. The sound is very live like a real performance and the speakers have disappeared!
I never knew passive preamps can retrieve latent information from source components and make such an improvement. The last passive preamp I had took away details and information, so this is a very, very impressive upgrade.
I look forward to the unit being fully broken in.
Thank you very much,
I received my Axiom a couple of days ago, and finally found a bit of time to sit down and listen with it. I'm very, very impressed! Big, detailed, involving sound, no "edge" at all, from a tiny box at an astonishingly low price!
At the risk of sounding like all your other testimonials--I received the Axiom preamp and it sounds awesome!
Wasn't sure what to expect, as I am using it with the power section of a basic NAD integrated. Much more detail and clarity, but not in any way or painful. To my ears a big step up. I am having that wonderful experience of wanting to listen to all my old music again. Many thanks for a terrific product, and so affordable.
The Axiom arrived few days ago. Just out of the box and connected to my
KingRex amp, I can affirm with no doubt that along with second hand
Goodmans Maxims I got last month, It is the best gear I've added to my
system. Both little sized and cheappp...!
The Axiom ads detail to highs and mids, precission also. Now, I have
more bass , more space between instruments. A great passive atenuator,
no hesitation please. You can use as a opinion of a happy customer.
Happy new year.
The Axiom is stellar! Interestingly, the first few hours the high end sounded harsh. I don't know if the Axiom needs some break in time or not but that seems to be settling down now. But the detail is improved across the spectrum, soundstage is deeper and wider, and it just sounds more realistic, like the musicians are here in the room. It sounded great before but now when I close my eyes I am really convinced that the band is here with me, it's pretty magical sounding actually. (hmm - not sure if "magical" is an audiophile approved term?) Kind of surprising since I was using my "XYZ" preamp in bypass mode. I would have thought that it was not coloring or limiting the sound, but it was.
I just wanted to let you know how pleased I am with the quality of your Axiom preamp. I've been using it for a week now & it continues to amaze me! I will be leaving a glowing feedback for you on audiogon this weekend. Your product has exceeded my expectations.
Kind regards, Jerry N
Unbelievable! Such an amazing product, at such a fair price! I was curious - now I'm hooked. Outperformed much more expensive gear in my second system. Thank you Tim...take a bow! AAAA+++
Synchestra Signature & Synchestra Reference IC Testimonials
Tim, here's my testimonial for you:
"Over the past fifteen years, I've had the pleasure of using various Luminous Audio cable products, in my factory and home systems. I've tried almost all of the cable brands on the market, and they seem to fall into two groups: those with a natural and sweet musical sound, and those with a heavy personality and "sound" of their own, often shifting the timbral balance. Although I presently use several different brands of cables in my various systems, I prefer the "natural" type of sound that Luminous Audio cables offer : sweet and open, and always highly musical."
Albert Von Schweikert
I believe I am one of the first to actually get a pair of Tim Stinson's newest and best interconnect cable, the Synchestra Reference, so I thought I'd share my impressions. I don't think Luminous even has these listed on there website yet.
Analog Front End: Sota Star Sapphire/ET-II/Benz Ruby
Phono Stage: Jeff Rowland Cadence
Preamp: Jeff Rowland Synergy IIi
Amplification: Jeff Rowland Model 12
Speakers: Martin Logan Quest Z w. 2 BagEnd Subs.
Interconnects: "brand X"
Speaker Cable: Straightwire Crescendo Biwire
Power Cords: TG Audio Silver
Power Tweaks: Shunyata Hydra, Wattgate outlets, PS Audio P300, PS Audio Ultimate Outlets
Isolation: Relaxa Racks, Aurios MIB, Paul Miller Pods.
Room: Dedicated listening room of approximately 33' x 22' x 11' with dedicated power supply.
I replaced the "brand X" interconnect between my turntable and phono stage with the Luminous Audio Synchestra Reference interconnect. The "brand X" has been my reference for almost three years and was chosen because of its musicality and resolving capabilities without the etch and glare which most highly detailed cables suffer from. Like many audiophiles, I have had a fairly constant stream of cables circulating in and out of my system, including some of Luminous's earlier interconnects, and none of them had managed to displace the "brand X".
Prior to doing any critical listening, I let the cables burn-in for a full week. All of my listening was done with my analogue front end ( I have another pair coming which I will hook-up to my digital front end; let me know if anyone wants my thoughts on that). I listen mostly to acoustically recorded classical and jazz music. My critical listening is done principally with large scale orchestral works and 60's jazz. I also throw in the occassional female vocal LP.
The Synchestra References are extremely fast. Initial transients have a snap-to effect that I have never before experienced. On certain recordings, such as the first track of Kitamura Swing Sessions, this created greater sense of "you are there" than I have previously experienced. Higher frequencies are revealed in fine detail without becoming harsh or etched. This allows minute audio cues to come through without creating a sterile musical environment. Bass is tight and fast - no sense of bloat whatsoever. The kick drums on Sheffield's Michael Ruff LP were as quick, tight and natural as I've heard.
I believe my system is fairly neutral (what audiophile doesn't) and these cables allow my Rowland gear to reach new levels of resolution while giving nothing away in the areas of image size, image location, soundstage depth and width, and pace. My only reservation is that I imagine the Synchestra References might be too much of a good thing in a system leaning toward the brighter side.
While I am not normally concerned with the aesthetics of my cables, it is probably worth saying a few words obout the Synchestra References. These are not fancy looking cables. The "brand X" are far more impressive. There is no shielding whatsoever and the mesh jacket is fairly simple. If you are looking to impress your friends with python-thick multicolored ICs, these are not for you. If you just want great sounding ICs, I haven't heard better.
Received the cables today - they were in great shape, no shipping dings.
I just put in the SS interconnects and listened to 2 songs. I can't believe the depth of stage they show right out of the gate! It seems like the performers up front took a half step back, but all the background players went waaaaay back to where they should be. I never realized how 2-D my "brand X" cables were - and they had better depth than my previous cables did.
Very impressive right off the bat - I cannot thank you enough for your cables - makes me want to listen to all my discs all over again.
Some time ago i received your Synchestra Reference and Signature ICs, and
I am very pleased by their performance.
Without getting into detail, let me just say the Synchestra does it all
right, very good resolution, everything seems to fall into place and
nothing distracts you from enjoying the music. There is just more of
everything, without adding a flavour. I guess you could call that
neutral, something the other cables I tried (brand A/brand B/brand C/brand D/brand E/etc...) would not offer.
Although I took chances by ordering your cables without demoing them
first, trusting in a few reviews I found in the internet, I don't regret
the purchase at all.
For the first time, I feel like I'm not in the market for new ICs any more.
Also, it was great doing business with you, thanks again for answering my
numerous emails promptly and sending out the cables immediately.
all my best, and have a great weekend;
Mr. Stinson, I'm glad I tried your Synch. Sig. Makes my "brand X" sound like it has bloated, dirty midbass, lack of LF extension, lack of HF extension and too much lower treble energy. Kind of like the letter M on a chart, where flat would be the bottom of the middle v (a capitalized M)...
Congratulations on achieving very nice LF and HF extension without sucking out the midband. I like having the extension of silver and keeping midband warmth.
It is some months since I received the ICs, but I guess it takes that long
to develop a lasting impression, not to mention get over the burn in period.
My impressions are extremely favourable. The sound is very full, yet (not
sure why this should seem paradoxical) dynamics at all frequencies are
amazing - an effect that really brings the life in the music to the fore. I
have gone through lots of cables, frustrated that each has its peculiar
flavour, with each different flavour appearing to bring nearly as many
minusses as plusses.
...But the Synchestra Reference just lets the
music burst forth, like the real thing does, and the improvement over the
"brand X" is amazing. Most noticeable of all is the combination of speed and
weight to the bass - usually these are in conflict with each other - for the
first time in my experience there is an unequivocal improvement in both. In
fact I cannot recall any interconnect creating such an unprecedented
improvement in my system before. Remarkable since I have tried so many
cables at around and above the price of the Synchestra Reference.
A week ago, I replaced my "brand X" interconnects with Luminous Audio Synchestra Reference interconnects. In the first 24-48 hours of use, I was not blown away by the sound, although there were aspects of it (dynamics, speed and treble smoothness in particular) which unquestionably bettered the SSIIs right out of the box.
Last night, after a few more hours of burnin, sounds started coming from all around the room, and from further behind the back wall than I had imagined possible. I was indeed blown away. No need to look at the receipt.
In your head you have an imaginary stereo and an imaginary friend who gives you advice. There's a real world outside your head. Give it a try!
I bought it, so may as well use it. After a couple of hours I was at a loss for words. The LSS sounded more like music than any IC I have used before. Over the next couple of days I continued swapping out all 3 ICs and really started scratching my head??? The "brand X" appeared more lively with lots of sparkle and detail, the "brand X" had about the same magic as the "brand X" with better bass and dug deeper into the recording in bringing out all the subtle details. The LSS has better and more powerful bass than the other contenders.
The LSS has a midrange and high end that is as sweet as your components can dish out. I was floored, I continued switching CDs and even added a few that had what i would call agressive content( Songbird by Eva Cassidy # 9 Oh, Had I A Golden Thread) Second half of this song gets
agressive with very high highs that on the other contenders made me turn down the volume, not so with the LSS. Smooth as a baby's behind. This is a wire that will not grab you at first, in fact I would bet that if anyone were to audition the LSS with other top notch ICs, the LSS would be the first one retired. No added sparkle, no Angelic highs, just gloryious music. I even went back and tried the LSS and others on the SS pre amps, the LSS came out the winner. I must confess that after hearing all the sparkle of the other two contenders
on the SS pre amps I just discarded the LSS as being dead sounding as if someone threw a couple wool blankets over the speakers. In the beginning the 2 and HT grabbed my attention the LSS did not. The LSS has all the detail and sparkle of the others, it is just presented in a different and hard to describe manner. The LSS to my ears is just plain musical with great bass extension and a HUGE soundstage( I believe the 99 plays a large part regarding the soundstage)
everything just sounds correct and natural. For one day I had a pair of "brand X" and tried my old pair of "brand X", the LSS prevailed. The LSS will remain in my system until bettered... I have sold the 2 and 3 pairs of "brand X", the LSS is that good in my system and with my ears, YMMV.
I just wanted to compliment you on these cables. I was getting discouraged
with all the changing out I was doing with cables. But the buck stops here
with these cables. I have found what I've been looking for. These cables
are just magic and have brought muiscal happiness back in my life again.
I have gone through quite a few cables to find the right mix. "brand X", "brand X". "brand X", "brand X", "brand X", and finally
the "brand X" cables I was currently using. I can't imagine going back. These
cables are here to stay!
Silver Reference IC Testimonials
The Silver References are definitely cut from the same cloth as the Synchestra References. Bass is articulate and tuneful. Midrange glows when it's supposed to and growls when called for. Highs are extended without being unnatural. If anyone tells you that silver interconnects are bright, I can only say that the Luminous Silvers added an extra dimension of life to this performance without the slightest hint of brightness.
They are more articulate, more open, more "you are there", and present more inner detail than any interconnect I've ever experienced. I put my money where my mouth is and bought three pairs.
I think for the first time I'm hearing the limits of the electronics. These are absolutely amazing!
Ok. - as promised - I'm getting back with more info and response re.
the cables. The system seems to have stabilised now.
1. these cables are beautifully transparent - imaging and tone are most convincing. I can close my eyes and it's (almost) like being there - 'there' being the Stavanger Concert Hall. Perhaps more accurately, I believe I'm getting much more of what the recording mix engineer laid down.
2. The transparency has a sigificant impact for the system as a whole, in so far as I now can hear significant differences in the system depending - for example, on which base(s) the equipment is mounted on.
This has allowed me to get far more out of the system than I'd imagined was possible. This principle also extends to the speaker cables, in that mounting them off the parket floor also seems to reduce 'noise'.
3. The overall sound of the system is clear, transparent, musical and .
. hmmm .. perhaps 'unstressed' is an applicable adjective. I'm very happy so far.
4. I tried alternative and bi-wiring combinations with my old cable and the Luminous spkr cable mixed.
No contest ! At first I thought the old cables might have sounded more dynamic, but on careful listening I rather quickly concluded that they were just noisier. The interconnects I used previously are for sale if anyone is interested.
5. The Synchestra Silver Sig interconnect cables are in my opinion - truly excellent. I cannot imagine needing or wanting to upgrade these.
Though not inexpensive (by my modest standards), I regard them as providing great value for money, and I must congratulate you on providing such a fine product.
6. Synchestra Signature spk cable - ditto -.
As I'm sure you will have gathered by now, I am no Hi-Fi scribe and I find it difficult to describe my musical &/or technical findings much beyond stating my delight with the purchase. Perhaps it will suffice for me to say 'thank you' for helping me get to where I can now experience music at home and on tap, and if that isn't enough, then . . . No - you can't have these cables back!
Peter S. at Venice Audio (CA) has urged me to share the feedback I
gave him about my recent experience with the Synchestra Silver Reference
IC's I purchased from him as demos. So, here it is...
BEGIN SYN SILVER FEEDBACK--------------------------
Dear Peter ----
Once again, I am startled to discover that interconnects can make as much or
more difference in the overall sound of a system than changing major
The new IC's were installed Tuesday night after 3 days of burn-in. I placed
them in my analog signal chain, one silver IC between the turntable output
box and my phono stage, and the second IC between phono stage and the
passive signal control box that is upstream of the active custom line stage.
Even with 3 more links of non-silver LAT Monarch II IC between the silver
IC's and the amps (signal box to line stage, line stage to subwoof
crossover, then crossover to amps), I am hearing major changes in my
Immediately obvious is the appearance of much-improved nuance throughout the
audible bandwidth. This is most apparent on well-recorded classical music.
There is a much more rosiny burr to strings which I have rarely heard in
audio systems, but which I was recently reacquainted with during a
live-music epiphany I experienced in London this past summer. Brass are no
longer hard. I think I am now able to discern the timbral difference
between a solo oboe and an English horn for the first time. To my surprise
the bass performance, from upper bass right down to the floor, is tighter
yet more natural sounding, with better musicality to the bass line. I had
recently been feeling that my analog chain was somehow bass-shy, perhaps
because I am using the older Graham 1.5t tonearm with the Lyra Titan-i MCC,
a tonearm which certain reviewers claimed to lack the last iota of bass
extension. With the Synchestra Silver Ref in the chain, the bass is rather
more solid and fulfilling. Certainly there is much more _ease_ in the music
when played through the Synchestra Silver Ref. It is clichéd audiophile
thing to do, but I have been pulling all kinds of classical LP's off the
shelf that I have not listened to in years because they previously felt
somehow drab and uninvolving. Now, with the Syn Silvers, they are much more
engaging, tuneful and involving. By contrast, some of my favored
pop/rock/electronic music is being revealed to be lacking in dynamic
contrast, flat or opaque-sounding compared to the better classical/acoustic
source material. At the same time, I have have electronic albums that were
very well recorded which are, like the orchestral works, revealing whole new
levels of detail, complexity and involvement lacking in many old pop
toe-tappers. The latter can be relegated to my iPOD. The good stuff, pop
and classical, I am going to savor on vinyl.
Plainly, I am very pleased with the Synchestra Silver Ref IC's. So much so
that I am starting a special little budget fund to purchase additional IC's
to complete the entire signal chain with Syn Silver Ref. I'll be needing 2
half-meter pairs, a 1.5-meter pair and, I cringe at the cost, a 3-meter
pair. I am equipped to chop and terminate my own IC's (even have a solder
pot), so may be able to save a little by cutting down longer cables to what
I need, providing I can obtain the correct Eichman bullet terminators and
there is no special technology involved in the terminating process.
Thanks for enabling this step forward in upgrading my audio system. It has
been a pleasure dealing with you. I wish you all good fortune during these
challenging times for the retail world, and I will do some word-of-mouth to
network your business as opportunity arises.
END SYN SILVER FEEDBACK------------------------
Happy New Year!

I hooked up a pair of your cables to the special phono stage I used with my mono records. I had an old pair of Synchestras on there before. I really didn't expect much, but I figured I had the cables so what the heck? The difference was clear, immediately. Some early LP's sound very, very good. The recording engineers' techniques were rather simple, but they also didn't have so many toys to monkey with, and screw up the sound.
I played a 1951 Westminster LP of music composed by Boccherini, performed by the London Baroque Ensemble, and conducted by Karl Haas. (The disk must weigh close to 200 grams!) I noticed immediately that the instruments were much more recognizable from one another, and not just part of a ball of sound between the speakers. The bass violin was very clear and not just a source of blurry, low notes. The violins sounded cleaner and more extended. Transients were cleaner too. I ended up playing four or five records, just to hear the difference. The improvements were consistent from disk to disk.
I thought it was neat, because I didn't know what to expect. I'm glad the cables worked out so well.
Synchestra Signature Speaker Cable Testimonials
...I swapped out the "brand X" first and compared to the Synchestra Sig. No contest. Really, better in every way. Again, as with the Synchestra Ref when added between DAC and preamp, the change to me involves SPEED, for one. As Jane Monheit changes inflection/intonation in the midst of a phrase or note, for instance, those nuances are not obscured or blurred over as they were with the "brand X". There is also greater freedom at both ends of the frequency spectrum, highs seem to reach up more easily and lows the opposite.
The soundstage is more 3 dimensional as well. The speaker cables really were a revelation. The "brand X" is a very good cable I think, even though it is modestly priced. But everything opened up about another order of magnitude with the Synch Sig speaker cables in line. I think that my speaker was voiced with the "brand X", but the overall tonal balance remained intact with the Sig in place.
I don't know what the system has in store yet, because I'm not sure how much improvement I can obtain from digital source. I suspect the system is limited by transport and DAC at this point, and no telling how much better it can get with that improved.
After getting the Synchestra cables connected I stayed up until 2 am listening to music. Although these cables are just starting their burn in, they still were able to add a whole new layer of musical detail (as well as stripping away a great deal of the artificial tonal colorations that were masking or distorting the natural timbre of the voices and instruments). They made all my recordings sound new again, but for the complex musical textures of large orchestral works (and opera) the improvement was mind boggling. The subtle nuances of humor and emotion were
revealed without over emphasis, the tapestry of complex tonal colors was breathtaking in its clarity. The sound of each instrument and voice seemed to reach my ears directly from their discrete positions on the sound stage without any sense of the music being output by the speakers. The acoustic reverberations of the hall or studio where each piece was recorded were distinct and almost holographic (when I move the CDP and AMP out of the listening room this low level detail will be truly stunning).
The best recordings in my collection left me awestruck with admiration for the composer, the conductor and the performing artists. I felt like joining the applause of the audience. All of these impressive impacts were achieved and the yet the cables have just started burn-in!
I cannot thank you enough for these lovely cables. They will vastly increase the pleasure I take in my recorded music.
... You should take great pride in what you have achieved.
Those cables came in today, in a word WOW! You know the feeling, the one where your short hairs stand up and you get that silly grin...yeah the one. What was most impressive was the spatial resolution, I was completely unprepared for how articulate and distinctive the various instruments and voices in the arrangements became. I'm not rich, so experiencing such a tangible return on my investment right out of the box is very gratifying, particularly in these times...so here's to you and your high speed team, you make one heck of a cable.
Allegro Cable Testimonials
Just received the cable last Saturday in perfect condition and right away install it to my system. First impression after ran it for a few minutes, it sounded sweet, natural and refined but not yet opened up the sound. After keep playing till 15 hrs the changed show up and the dynamics, full sound without edginess that I crave so much about your cable suddenly appeared. The sound started to open up and keep improving. I love it. The strength of your cable are always musicalities,emotinal/soul stirring without being analytical, big, bold full sound, dynamics are excellent, natural/realistic and never get bored. 3 D image is very good and the bass definition is top rate among other cables that I've tried before. It doesn't sound dry at all with good details and resolutions. And finally the price is worth every penny. Athough I have to pay 30% more for the currency differences now, it doesn't matter as I got a very good quality cable. The world needs more people like you as not everybody can afford expensive gears or cables and I am one of them. My system comprises of products with affordable prices but with excellent qualities. Only a few companies have the same philosophies like yours: Almarro of Japan ( Mr. Yoshi Muratmasu san) that I also respect for its affordable tube amplifiers ( I am using 318 B one), Mr. Peter Qvortrup of Audio Note Uk with their affordable speakers AZ two and DAC zero. Although Audio note products considered very expensive, they do make affordable ranges too which I am now using and finally yourself Mr. Tim Stinson with your amazing audio cable ranges (Renaiisance speaker cables, Allegro digital cable, etc) which I think made possible for ordinary working class guy like me to enjoy a high end quality of sound without having to sell our home or something. As you said: Music so clear,you can see it! Because Music matters.
OK Tim. So now I have Luminous cables throughout my entire system--digital, analog, power.
Sounds mighty fine! Detail, dynamics and depth galore...
I finally got an opportunity to critically listen to your beast, and I am very impressed. Previously I've never given much thought to power cords except making sure that I'm using one that is large gauge and well made. However, comparing your power cord to a stock IEC cord last night continued to convince me of just how fantastic your products are. When I switched from the stock IEC to the beast, it sounded like the music shifted into focus. There was also added depth and texture which added nice body to the recordings. You keep impressing me Tim no matter what products of yours I try. I don't know how you do it, but I'm proud when I tell people that my system is all Luminous Audio.
First the cliches; Best $600 you'll spend on your system. Power cords do make a difference... it's as if a veil was lifted. They all apply to the Mega Power Lynx, big time. I had recently purchased an expensive tube integrated and tried a few similarly priced power cords without any spectacular results. I kind of figured the amp was designed to work well with any decent cord. I decided to try one more cord based on the enthusiastic reviews for the Mega Power Lynx. Immediately after plugging in and warming up, I started to hear what can only be described as more music to my ears. The improvements are beyond lows, mids, and high, it's as if something is going on at the molecular level. On my favorite recordings that I have listened to hundreds of times, it sounded like everyone in the band upgraded their instruments and the singer bought a new mic. The plaque build-up has been removed, and the blood is flowing more freely from the heart to the organs. Highly recommended.
Well, what can I say? My system never sounded so well....
What amazes me is the 3D scene, almost holografic...
Very very good.
I have auditioned the MEGA POWER LYNX twice in my audio system - AMAZING power cord - very, very well done !!!
I did just what you suggested on the PC - put it in my system for about two weeks, then removed it.
WOW! Impressive. I think part of what I'm hearing is due to the fact that the cord has broken in, as the sound I'm hearing now is not quite what my initial impressions were. While it still retains the 'robust-ness' I initially heard, it's not quite as heavy handed.
It seems smoother, even though it still has a weighty, full sound. Also, I really don't get the feel that the highs are rolled off like I did at first. Very evenly balanced and smooth, just like the Synch Sig interconnects are.
I really wish I had that $1500 JPS cord that I mentioned earlier being impressed with when I auditioned six or seven PC's from 'The Cable Company'. I think this cord is right up there, and I'd love to do a head-to-head comparison.
Anyway, I definitely think you have a winner here!
I definitely would like to purchase at least one of these "big boys" and congratulations on a great power cord!
The Power cord of Lynx already been played for about 100 hrs and it's much more open and transparent now with great details and as always with your cables: very musical and much less edginess sound. The emotion of the song is really apparent and I don't want to stop listening.
I had multiple eargasm songs after songs with my cd collections. From Patricia Barber Modern Cool album, Companion album, Selena Jones albums, Charlie Antholini knock out 2000 album etc.
It doesn't matter what songs are they, the power cord just deliver effortless sound with great balance between dynamics big bold sound and refined smooth sound, sweet but open transparent sound with musicalities to match.
In short, It's a great cable and make my system sounds better and more musical than ever. Thank you very much for letting me experiences the magic of your latest power cord. Bravo to your team design Tim, you've got a winner again.
Because I have tube mono blocks and virtually no interest in digital sound, I put the cord into my preamp. The sound was really, really wonderful: crisp cymbals alongside deeply articulated bass notes. Great imaging and three dimensionality.
I couldn't be any happier with the sound off my records! Wow! This is fabulous! This is THE BEST arrangement of all the power cord tests I performed!!!
From D. S., Va.
Very quickly, here are a few observations.
(1) My Coda S100 amp has always sounded like the powerful beast it is, but now its power reserves seem unlimited, at least for my purposes.
(2)The midrange and highs have an open, effortless clarity that I I've never heard in my system before. Forget "Solid-State glare" in the middle and upper registers. My Audioprism Noise-trappers helped a lot with this issue, but now the grit that remained is gone. Period. If I become fatigued by the music, it is because I have the volume turned up more than I realized. This characteristic is particularly evident when one listens to female vocalists with dynamic, complex voices. Ann Wilson, of Heart is a perfect example of this. Ann Wilson has always been an incredible rock vocalist, but time has added a huskiness to her voice that is devilishly difficult to reproduce without making her sound "screechy." With your new cord feeding the Coda, she sounds like she should; She sounds raw, and powerful, but very feminine too.
(3) The stereo image has much more of a "walk around" stability than it did before. The instruments of backup artists are more noticable, and well placed.
(4) The increase in bass power is a head shaker. Bass notes are not just sounds, but shock waves one feels viscerally. My speakers, as you know, use a ported design for the subwoofer cabinets. It is much harder to get well-defined bass from a ported design that from some other woofer/cabinet configurations, especially at higher volume levels. This characteristic is not really an issue now. The bass notes are quick, and concussive. The big Coda has taken control, once and for all. This characteristic is evident at all listening levels, which is even more remarkable.
Why does a power cord matter this much? I don't know. I can understand why signal-carrying wires like interconnects and speaker wire make such a difference, but I was not prepared at all for the difference a single power cord made in my system. Using your new "music hose" to feed the big Coda let the amp show that it can pump out better sound than I ever expected. I can't go back to what I was using before. Your cord ruined my sense of satisfaction with my system's sound, because I have heard what my gear can do. You have two sales. My wife wants a cord for her rig also.
If I was forced to make a comparison, I would say the difference your cord makes is like using a high-performance engine before and after adding forced induction. A normally aspirated engine uses lots of power just to draw the air/fuel mixture into its combustion chambers. On a turbocharged, or supercharged engine, the intake valves open, and the air/fuel mixture is forced in, under pressure. As the engine revs up, pressure increases and more power is produced, within the limits of the engine's design. The words "Turbocharged," and "Supercharged," are overused greatly, and usually incorrectly, but that is the comparison which came to the mind of a person who spent 16 years in the car business.
I'm glad you found the comments useful. I thought it was an apt comparison, because of the effortless way the big Coda now handles transients, and other dynamic swings. There is no waiting for the pow
What do I think?
(I can't believe you let me wait so long to try it...)
I'm very "in tuned" to my system - It took all of about 10 seconds to realize the (positive) difference.
Hi Tim & Richard,
I've had almost a week with the Mega Power Lynx now, and I'm very impressed! As you know, it's providing power for a 1kW transformer that's supplying symmetrical AC to several digital source products here at the network. Immediately upon adding the Mega Power Lynx, the music (or voice) seemed to "come alive" - one of those things that makes you sit up and take notice. To make sure I wasn't hearing things, I reinserted the old AC cable (a decent conventional 10-gauge), and sure enough, whatever was coming from the speakers was a bit less alive and a little more boring!
The other major change I noticed was an increase in localization of the image (whether voice or music) created by the system. It's much easier to pinpoint where the voices or instruments are coming from - another improvement that makes the system sound more "live" and less canned.
I anticipate that further listening will uncover more improvements. But even in this brief amount of time listening, it's obvious that you and your associates are really on to something with the Mega Power Lynx. Congratulations on a fine product!
Just a quick feedback; I have the Mega Power Lynx on my Audio Space 6M-300PP
power amps for two weeks now and would expect them to have burned in
sufficiently. The sound was already amazing from the first day and it keeps
on getting better still. The Mega Power Lynx cords replace my Brand X cords which are by no means of minor sound quality. However, the LAT
Mega Power Lynx cords are simply outstanding in the way they produce a
better sound stage and allow a more layered presentation of the sound
compared to the Brand X cords. I will still have to try them in my main
rig in Hong Kong where I use Lessloss DFPS cables to connect my ASL
Hurricane II power amps and ASL Flora Ex preamp, but I can say already now
they are truly great power cords.
I have been made aware of your Mega Power Lynx cords by a review of other
equipment in Bound for Sound, when the reviewer mentioned that he thought
the issue of power cords was laid to rest by the Lessloss DFPC Signature
power cable, but found that the Mega Power Lynx cords had reopened this
issue again. Given the fact that in my system power cord changes have a
higher impact on the quality of sound reproduction than any other cable
changes, I have always been on the lookout for the best possible power
cords I could find at a reasonable price. The article in Bound for Sound
made me curious enough to order the Mega Power Lynx cords. Well, I can
confirm after having used two Mega Power Lynx for some time now that these
are the best power cords I have heard so far in my system. I have previously
used and am still using in my main and secondary system Soundstring (for
digital equipment), Zu (not in use any longer), Black Sand and Lessloss
power cords, but I am now slowly changing all my power cords to Mega Power
Lynx. The Mega Power Lynx are providing me with a more detailed and more
layered musical picture compared to other cords. Their lower frequency
rendition is just exemplary, as it produced a tight and better defined bass
than other cords I have used so far. Based on the experience in my systems I
tend to think that the neodymium magnets at both ends of the power cords are
responsible for the extraordinary rendition quality that I can experience
with the Mega Power Lynx cords in my systems.
In summary, for me the issue of power cords is solved through the Mega Power
In addition, the sterling service I got from you makes it easy to highly
recommend the LAT Mega Power Lynx cords and Luminous Audio Technology.
Tim, As you know, my wife and I moved some time ago, and I just got around to setting up our stereos.
Using your power cords on my two-chassis Coda S100 amp made a very noticeable improvement over
the stock cords.
My Audio Research SP17 preamp has never really "blown me away," sonically. The AR unit is better than
the Parasound Halo preamp it replaced in some ways, but it falls short in some ways too. The bass the
AR SP17 produces is not nearly as powerful and punchy as the bass the Parasound Halo cranked out,
though the SP17's bass is well defined and nicely integrated into the overall sound.
When I hooked up the components in my equipment rack, I still had one of your LAT power cords left,
since my wife's stereo is now in our living room, and she didn't want a big cord running across the floor.
I decided to plug the remaining LAT cord into the AR SP17 preamp as an experiment. When I attached
your power cord to the SP17, I was very surprised. I actually flinched when a Stevie Ray Vaughn track
pounded into the room. The sound from the "vintage" Dynaco A-50 speakers I used to set up and test the
equipment rack had been decent, but not mind-blowing. Bands and orchestras sounded like there were
little people in the speaker cabinets, playing away. The A-50's didn't seem to "project" very much. This did
not surprise me, given the speakers' 1971 introduction date and their stock crossover parts. The A-50's
have also been sitting for almost 18 months, which is never good for gear.
With your LAT power cords plugged into the AR SP17 and the two-chassis Coda S100 amplifier, heavy
dynamic passages exploded into the room. The imaging was much sharper. The glare I heard on older,
1980's-era rock disks was reduced. Dynamic range improved dramatically. Every aspect of the sound
was better. Vocals really moved out into the room, and made me see why the Dynaco range of speakers
were so well regarded for their abilities in that area.
Why does a preamp that draws so little power need a 9 gauge power cord? I don't know. I only know
what I heard. I really didn't expect much of a change at all. I just wanted to try the cord in the system,
since I had it lying around. This was definitely not a case of, "Oh boy. It has to sound better." I had no
expectations. I merely figured that I should try the cord, since I had it. I am glad I did.
Tim Stinson and I had been going round and round about the effects of a good power-cord on improving the musical experience. So I finally tried a few of his Mega Power-Cords in my system. Please take the time to read my results (and surprise) below about how a power-cord can affect the sound...
Tim brought a few of his Mega power-cords to my home for me to try on my dedicated 2-channel listening system, which I have set-up in a dedicated acoustically-balanced listening-room. A brief overview of my system, first...
I have over the past 15-years evolved my listening and system to a point presently where I am extremely satisfied with the sound. To me, my system sounds very natural, dynamic, accurate, musically real and satisfying. My components presently are:
Border-Patrol S20-EXD Dual-mono Parallel 300-B SET
Balanced Audio Technology VK-D5SE CD
Balanced Audio Technology VK-P10SE Phono
Living-Voice OBX-RW Speakers
Teres 265 Turntable
Dynavector DV-507 MkII Tone-arm
Shelter 9000 Cartridge
ZU-Audio Event RCA interconnects, phono-cable and speaker-cables
My system is very detailed, dynamic and musical (your individual mileage may vary !) and I have had several audiophiles tell me it is one of the most-resolving and real-sounding systems they have ever heard. While it is pretty easy to detect differences in vacuum-tubes, speaker cables and interconnects, etc., I was a little skeptical to say the least about the effect a power-cord could have on the musical experience.
I was using simple and inexpensive Signal-Cable power-cords and I really couldn't tell the difference when I switched them in to replace the stock power-cords. I guess that change increased my skepticism as to the influence power-cords have on the sound.
When I installed the first two power-cords in my S20 Amp dual power-supplies, then turned the power on, I noticed immediately that the quiescent noise had been lowered a noticeable notch. That both surprised and pleased me ! At that time, my best-friend and avid audiophile Dave was present and he noticed the same thing. In fact, he was the first to comment as such. We had prior to the power-cord swap just finished playing "I Don't Know Why" from the great Norah Jones Come Away With Me L.P., so we were ready to re-listen to see if anything had changed. Well... It did ! Playing this song with the new power-cords made a notable difference in Norah's vocals. There was more inner-detail available, and over-all the musical experience was even more enjoyable ! More accurate and true-to-life to be more-exacting.
I can only attribute this (to my knowledge) to two characteristics of these power-cords. 1. There is no ground-wire (third prong wire) attached at either end, however the prongs are there. (By the way, I tried my Signal-Cable power-cords with a cheater-plug eliminating the ground on the wall-outlet end, and it made no difference in the sound.) 2. The neodymium magnet "donuts" on either end seem to be having an attenuating-factor on any spurious higher-frequency noises getting to the power-supplies and thusly through to the supply electronics. This is even more surprising to me, as the dual power-supplies are quite noise-resistant !
While these power-cords are not inexpensive, the decision to purchase four of them was a no-brainer... While the additional two power-cords on the control-preamp power-supplies made another incremental improvement, it was not as significant as the two on the S20 amp power-supplies. In any event, the musical enjoyment and experience has been notably improved with their addition to my system. They're HIGHLY-recommended !
