Hello Mr. Louis,

My friend Bill Pace recently demonstrated your CD mat for me. I was amazed at the transformation it brought about in his system. His system is already a quite excellent one, well noted for its analogue-like qualities and intense yet relaxing musicality. I have had many memorable hours of enjoyment from listening to his system. I have also learned a lot from Bill, as he is quite the audio-scholar and gentleman. However, all those hours didn’t quite prepare me for what I was about to hear when he debuted your CD mat for me the other day.

We first tried a CD that I am quite familiar with (the remastered version of the seventies folk album by the band America ). We listened first without the mat and it sounded quite nice. Suffice it to say that I sat there slack-jawed in amazement when we subsequently listened with the mat in place. Noticeable qualities for me were a significant increase in soundstage size, seemingly unlimited dynamics, and a much smoother tonality ( the CD can be quite bright, especially on my system). But what was really gripping and revelatory was that it sounded much more like music. And music is why I’m in this hobby. My initial impressions were continually confirmed as we listened to CD after CD. Needless to say, I didn’t want to leave and go home that night.

I wanted to write and tell you that I feel that with your CD mat, and the proper ancillary equipment, you might have quite possibly made the vinyl disc obsolete !!! The mat seems to me to bring out the best in what I like about analogue, but without all the other detractions that I detest (e.g., the surface noise, the need for disc hygiene rituals, etc.). Keep in mind that this statement comes from someone whose vinyl disc collection approaches ten thousand, so it is not made without the consideration that I now might have ten thousand “frisbees” on my hands thanks to you !!! By the way, are you interested in a really good deal on a record collection CHEAP ??? LOL !!!

Seriously now, I want to offer you my congratulations on a great product. Keep up the good work. We greatly appreciate everything you do to bring us closer to the music.

P.S.  I have attached 2 pictures of my system in my media room. My equipment consists of the VPI TNT-4 table with a Graham 1.5 T arm and Grado wood body cartridge. Phono section is a Counterpoint SA-9. Preamp is the Pass Labs X0.2. My speakers are Revel Ultima2s driven by various amps (I’ve tried McCormack monoblocks, the LAMM ML1, Spectron Musician 2, the neat little BYOB amp, and George Wright’s tube amp, which belongs to Bill, and is probably my favorite)

Dear George,

Oh by the way, on BluRay the effect was such that I would NEVER want to watch / hear another movie without the damper…but the addition of either the red or the blue, or a stack of red and blue, was nothing sort of shocking..A friend of ours dropped by late on the way home from work [ he works afternoon-evening at Xerox ] and he got to see/hear the test…It was immediately perceivable to him too…clearly so….

At T.H.E. Show held in the Hilton Hotel, Newport Beach, California, June 3, 4, and 5th, 2011, the TruVoice Dampers were a big hit.  Many exhibitors including the manufactures of expensive high-end CD players and DACs purchased one or more TruVoice dampers to improve their presentations in order to increase their sales.  Of necessity the dampers were demonstrated under very tough show conditions to exhibitors who were more focused on selling their components than buying another company’s products.  The dampers were particularly effective at tightening up the bass for those manufactures who opted to save money by exhibiting in the smaller rooms.  After hearing the dampers some exhibitors were ready to hear the benefits of UltraBit Platinum-Plus™ (UBP-P) on laser-read media and vinyl records.  At one demonstration of a before and after UBP-P treated record a woman in the audience spontaneously asked if the volume had been turned up, so needless to say, the exhibitor who’d already purchased three TruVoice Dampers also purchased UBP-P.


Testimonials from very satisfied customers

Dear Rick,

Thank you for your interest.  You may read about the TruVoice Red Damper and TruVoice Blue Damper at:  .  I’m waiting on Michael Crock, the husband of Jennifer Crock of Jena Labs that’s also a dealer for the Digital System & Solution’s products that include UltraBit Platinum-Plus™ to take pictures of the dampers that I can put on the website and then add them to the shopping cart page.  You may call me toll free 7days a week between 10AM and 11:45PM Pacific time toll free to 888-588-9542 to order if you don’t want to wait for the dampers to appear on the website.  You may read about all the products including UltraBit Platinum-Plus™ at the website:  .  Both products will enhance the fidelity and musicality of the playback of all laser-read media.  Below you may find a copy of an email that I received from a customer who has the PerfectWave Transport and PerfectWave DAC.  Richard also has purchased four X-Links that I sell.

From: “Byers,Richard” Date: August 9, 2011 9:50:19 AM PDTTo: “‘George S. Louis’” Subject: Third Gen Red Damper
George, I call the new one you sent last night as the 3rd gen as that is the third gen as far as what I have.  I think you hit the proverbial nail on the head with this one. I fired up the PW system and gave one of my old war horse late evening jazz discs a whirl – the ubiquitous Kind of Blue. I have this on several versions but my personal late night favorite is the gold Mastersound CD transfer.  I know I have some work to do on my PW system as when I first started listening without the damper and just having UBP-P applied the imaging was diffuse and the sound was muddy, as if covered by a thick blanket. Now, I know my system does NOT sound this way so I know I have some Kontak cleaning and work to do.  Anyway, I inserted the new 3rd gen red damper you sent me last night and holy cow!  Suddenly, everything snapped into wonderful, live focus, the imaged moved a good 3 ft or so wider on both ends and depth increased substantially.  MD’s muted horn moved back several feet and came into focus but not only that, everything came alive like superior analog.  The bass which is usually pretty warm and thick suddenly became sharply focused and I could literally see the strings being struck by his fingers, the notes and overtones coming through superior as if live and in person.  The brushes on the snare were just, there and alive, every single minute stroke and sound.  Cymbals so real they were there, in space, I swear.  And that, with my PW system definitely out of shape!!!  This one is a keeper and just 15 short minutes with it last night makes me think I can not live without it.  I have much more work to do with audio and BD playback to know along with A-B comparisons with the 2nd gen red damper.  But, initially it just shocked me.  I had to put a yellow sticky on the jewel case marking each one so I don’t get them mixed up since they look identical.  Whatever you have done, you did it and then some.  This sounded marvelously warm, sweet and natural and just live last night.  But, the live nature of it and in the room sonic just shocked me it was so apparent.  Night and day different.  Sweet Fancy Moses! From what I heard last night I was very happy but of course need to test under different discs and of course BD comparison. If on my KURO plasma it looks like it sounded on my PW combo last night I will be head over heals in love I think.  More to come!!!!  On to the second phase here.  I would like to inquire about another X-Link for usage between my PWD DAC and preamp.  I would need a 2-meter length I think to have enough length to do it right. A 1.5-meter might work but would be very tight with regard to the ends being bent rather than a nice easy curve to insert.  Let me know what your thoughts are on pricing for it.

Best, Rick

Best regards,

P.S. At Music Direct  I spoke with Roger there and he said discs that they were having a hard time copying CD but after the CDs and CD-Rs were treated with your UltraBit Platinum-Plus then copied perfectly, and that L*******n was old hat. Hello George let me tell you a story, last night I had George Harrisons Live in Japan One disc was treated with Artde son we played a song.  Then I cleaned it and retreated it with your UltraBit Platinum-Plus CD cleaner and all three of us not only heard the difference but went from hearing one song to listening through the entire CD.  We all thought the performance was much more organic and natural sounding. George you may put this comment on customer feedback if you wish.

Hello GEORGE it was good speaking with you.  I am looking forwards to using your New CD cleaner and treatment. The one disk I did do with the old vs the L*******n your UltraBit Platinum treatment brought more realism to the performance.I also want to hear how much of a improvement your CD damper does for my system. I am hoping that it will bring greater resolution without changing the perspective of the performance like the the M*******m did.  I want to thank you, and look forwards to using several of your products.

Dear Paul,

Thank you for your very kind words and letting me publish them on the website.  But when I publish them, everyone will know that you and your two friends listened to a CD all the way through.  That means that the three of you will be in danger of losing your official audiophile caring cards because real audiophiles as apposed to music-loving audiophiles don’t listen to CDs all the way through.

Best regards, George

Hi George,

Just a note to let you know that the disc mats are a real winner. I used the red one on my CD system with the wonderful sounding Marantz SA7-S1 and the Blue one on my Sony 5000 ES Blue-Ray DVD player.

I have not found a down side except you must take a few seconds to make sure that you center or off center the mat about a touch, due to the force of my door closing when I use it with the Marantz SA7. I have compensated for this and loading is 100% perfect.

The first CD I tried was the Beatles remastered Yellow Submarine. It sounded just fine before after using your Ultra Platinum (I just received the UltraBit Platinum-Plus) spray; something I have used for years now, so I figured a slight change for the better or perhaps for the worse. You just never know.

I hit play selected track 3 Eleanor Rigby it took perhaps 10 seconds too say hold on here, what do we have here? Vocals just jumped out with clarity and weight, transparency, dynamics, overtones, bass definition, bass impact, all better, but most of all you just wanted to sit back, RELAX, and enjoy the music.

It sounded just “right” for a loss of better words. I then played “For Duke” M&K Gold CD, now I have owned the original LP and with you red mat, and your Ultra Platinum Plus spray, well I finally forgot about the LP version.

The horns, the Saxes, have such presence that it was scary good just as this recording should be, being direct to disc after all, my Harry James Sheffield Labs 20 bit Gold Discs also had the same improvements. For the first time the CD surpassed the LP, pitch, tones, bass and definition better, I mean it just sound more “right” there is that word again. You cannot fool the ear and our mind, when it sound real we know it!

I put on a Frank Sinatra disc and it sounded so real, but now with no trouble at all you could hear the Capital studio and where they added a touch of reverb to his voice when going through different tracks on his Classics CD vol 1. Which were recorded at different times. I have never heard it this clear and so easy before, like a new-mastered recording! I sat their and just shook my head, and again that RELAXED word came into my head and I enjoyed the whole CD/recording.

Well I started grabbing my test discs that I use when trying a new piece of gear and did not even bother to use Ultra Platinum at first just to see how the mat did on its own.

Well I have to tell you it sounds real, real good, again I found myself just relaxing and enjoying the music. The whole presentation was coherent, imaging superb, and much more detail yet more musical.

After going through them a few times, I then added your Platinum Plus CD treatment, and sure enough things became more focused and micro details came forth a bit better, and much better in every way.

As you the know the mat has two-sides, one shinny, one more textured and both give a different presentation, this is cool because you can match which sides works the best for each CD you play thus improving your enjoyment. The shinny side gives you a more open sound stage and transparency; the textured side a bid more closed in, but in my system stronger and better-defined bass thus the feeling of more body to the music. That is my cup of tea.

However, depending on ones system, gear, and your likes, you have made it nice that one side or the other will work just fine, so you have much more flexibility.

If I were say how much of an improvement, I would have to say it was as if I changed out my CD player, speakers for a much more expensive equipment/speakers. I mean the improvement of the bass, depth and detail would have meant a new set of speakers the improvement is just that large. You have to hear it!

For once, I can say that digital can sound musically satisfying as the very best LP I have owned and all were 1st pressing the best for Sonics for vinyl, as you know.

I never been in the war of which format is better, I say enjoy what you enjoy as long as you enjoy the music, but I can say that digital even 16 bit does not have to take the back seat to any format. You just need to work with it as you would with the LP, right mat, cables, and in the CD players case power cords (ac noise) and a good foundation for the gear to sit on.
On video, the picture looked more colorful, and the audio had the same improvements when using the blue mat, though the red mat worked just fine also, but the blue mat is thinner and worked perfect loading in my Sony 5000 ES Blu Ray player. I am more into audio than video but I have to say watching a DVD was more enjoyable.

The best that can be said is that this product improves the reproduction of recordings and video, the mats and CD treatments are worth every cent asked, and for the improvement a stone cold bargain that is in my experience unheard of for the money spent.

The nice thing about your Mat and Sprays they will improve any system regardless of how much or how little you have spent. I mean really improve; you do not have to sit there and talked yourself into hearing the improvement, it that huge!

Did I find any down side, not really, just learn how to put the mat on to work with your particular player and once you have that down relax and enjoy. In other words, do not be afraid of using this disc with your player, both of my players the space is very tight when the door closes and I have had no issues, if I do not place it right, I just hit open and re-sit the mat and all is fine. But once you know how to place the mat I’ve hit 100% with no reload issues.

George great product, now get the word out, so all who care about “sound” gets 100% out of their system and recorded music collection. You have done recorded music a great service.

Better sound 100% that is for sure.

User Guide

The TruVoice-12 Solution Damper System™ (TVDS) allows for 12 distinct voicings for CDs, but until further notice don’t use the dampers in computers or slot loading players.  TVDS allows you to choose by ear the best combination and or permutation of TruBlue (TB) damper and TruRed (TR) damper for your particular system, media, and taste.  Each damper may be used two ways with either its textured or smooth side lying on the disc’s label, and 8 more ways when both are used at the same time for a total of 12 distinct voicings, as listed in the instructions on the back of the damper jewel case.  If 12 voicings seem like too many options, then consider this: many high-end and not so high-end CD players may have multiple low-pass filter options to roll off nasty high frequencies and or eliminate pre and post-ringing, oversampling options.  Here are some examples: if a CD player or DAC has 4 oversampling options plus 4 upsampling options there’ll be 16 (4 x 4) possible voicings, then if it also has 4 filter options, that’s 64 (4 x 4 x 4) possible voicings.  With two TruBlue dampers and one TruRed damper, but only using two dampers at a time, there’d be 4 more possible voicings for a total of 16.  Depending upon how many dampers your CD player can handle at one time, such as three TB, two TR dampers, or two TB and one TR damper, you may want to take advantage the increased versatility of even more voicings than the 12 of the basic TVDS. And none of those options to enhance the fidelity and musicality of your playback system comes with the inherent trade-offs of additional electronics!

Regardless of how many TruVoice Dampers you’ve chosen, the TVDS dampers may give you as many, if not more, system voicing possibilities than some high-end disc players and DACs.  Furthermore, many of the most expensive CD players and DACs sound better when CDs are played back with any of the TVDS dampers, using TVDS with an inexpensive CD players and or DACs, and it might just make them sound better than expensive high-end CD players and DACs without benefit of  TVDS.

A White Paper on the Art and “Science” of Mechanical Impedance Matching as it Applies to Unity-Coupled Dynamic Impedance Matched Dampers and How Art Frequently Leads Science

Dynamic Impedance Matching (DIM) is the term I use for the damping of rotating discs usually made of polycarbonate or glass, with data that are read by a laser pickup.  I believe in the scientific method and double-blind testing, and I think that anything we hear should, at least in principle, be measurable. But having said that, there are some aspects of sound the human ear-brain can discern in double-blind tests that either we don’t know how or what we should measure, or that might be below the resolution of present test equipment.  In my experience test instruments don’t connect emotionally with music or art, at least not yet.  The purpose of our products is to enhance listeners’ ability to make the closest possible emotional connection to music.  Hence the Digital Systems & Solutions slogan: Listen to Music Not Measurements or White Papers and Rehear What's Possible.

Here’s an example of why I believe art frequently leads science.  A group of scientists and engineers on a PBS Nova program made a replica of a Stradivarius violin.  First they used sophisticated test equipment to measure the sonic, physical, and chemical characteristics of the Stradivarius violin they’d been loaned.  Then they compared the sonic output of their replica to the Stradivarius by having the same violinist play both.  The sonic measurements of their replica were reasonably close to the real thing.  Unfortunately, I don’t remember the opinion of the violinist about how successful they were, but the violinist probably knew which violin he was playing, therefore, his evaluation wouldn’t have the validity that double-blind testing could confer.  Given the difficulty of their task, they accomplished a truly remarkable feat of reverse engineering that within the limitations of their measurements resulted in a replica violin that measured quite respectfully close to the Stradivarius.

But even if they’d created a perfect replica of the Stradivarius violin they only would have proved the point of their exercise (that they could duplicate the sonic signature of a Stradivarius violin). They never mentioned that the artistic achievement of Stradivarius when he constructed his masterpieces was more art than science.  To wit: if Stradivarius had all the best test equipment on hand to help him make the best possible sounding musical instruments, all the test equipment in the world wouldn’t have helped him one iota (except for possible quality control if he wanted to duplicate a given instrument), because his choices of the wood, varnish, glue, aging, construction techniques, exact size and proportions were essentially the result of his own artistic aesthetic judgments.  Thus without an example of a Stradivarius violin to replicate, the engineers and scientists couldn’t have made an equivalent sounding instrument from scratch, since they didn’t posses Stradivarius’ unique artistic talent to create something new.  At least the scientists and engineers knew that a Stradivarius violin was worth the effort it would take to replicate it, so perhaps I’m being a bit too harsh.  But ultimately the idea and creation of acoustic instruments is fundamentally art not science.

The reason I’m discussing the art versus science question is because I think that making disc dampers to dynamically impedance match a polycarbonate disc for the highest fidelity recovery of its data and timing for transfer to the rest of playback system’s components is currently more art than science.  If it were purely science, then we’d already have the promised “perfect sound forever.”  But since products such as UltraBit Platinum-Plus™, which optically treats CDs, and the MusicMat Gold™ disc damper, both improve the fidelity and musicality of CD playback, it’s patently obvious that CD sound wasn’t and isn’t perfect (see 30 Years of Digital at, but I digress.

How does this preamble apply to the making of DIM disc dampers?  The choice of materials and the Unity-Coupling™ between a damper’s multiple layers comprise the science of our damper technology.  But since test instruments don’t measure the effects of the damper on sonics and musicality, it’s what I hear plus my artistic and aesthetic judgments that Digital Systems & Solutions relies upon to determine if a particular damper increases the fidelity and musicality enough to convince the clear majority of listeners the improvements they hear are sufficiently worthwhile for them to purchase dampers at their MSRP.

In the final analysis, Stradivarius only needed to make violins that would sell to violinists and please listeners.  He didn’t have to be concerned with how other instruments sounded let alone the sound of the voice.  So in some ways high fidelity playback systems and media have a more difficult task since they must faithfully reproduce all instruments and voices.  Although some high fidelity components might be considered works of art by music-loving audiophiles, high fidelity equipment isn’t supposed to add or detract anything from a live performance, because it’s only function is to accurately reproduce it.  Therefore, some argue that high fidelity equipment should only be based upon well established scientific principles, and therefore, not upon artistic and aesthetic judgments.  I believe that both points of view are valid and not mutually exclusive to damper technology, which is a product of both science and art.  For numerous reasons such as microphone techniques, speaker arrangements, the acoustics of the playback venue, etc. there can never be absolute fidelity to live performances.  This means that the performance of every audio component is judged by each person’s expectations about how they want their system to sound.  So where’s the science?  At least where dampers are concerned understanding the basic properties of damping materials is a scientific starting point.  Of course science plays a major role in quality control, but the rest is pretty much the art of making disc playback that’s flawed please music-loving audiophiles.

Companies that sell audio equipment try to please the greatest number of music-loving audiophiles, and because no component is perfect, they have to make artistic and aesthetic judgment calls.  When I voice dampers, it’s essentially the same, because our company’s dampers have to work with a wide variety of playback systems for all acoustic and electronic instruments, male and female voices, and for every kind of music, as well as satisfy the artistic and aesthetic sensibilities of the vast majority of very discerning and astute music-loving audiophiles.  Our goal is that after they’ve heard the improvements our dampers make to their laser-read media, they won’t be able to listen to music without them.  It essentially comes down to testing the prototype dampers with nuerous musical genres, in my audio systems, many other systems, and listening to the very helpful opinions of numerous beta testers, but ultimately like Stradivarius, my ears, have the final say.  Digital Systems & Solutions believes the only thing that matters to you is when the music meets your ears.•
