Unsolicited feedbacks:

Just a few observations regarding the addition of the 'Prophecy' I2S to my PS Audio Perfectwave MK II DAC/Transport combo. I have incorporated "silver" cables in my system for many years. I am using Kimber KCAG throughout my Krell/VPI/Wilson setup. I was using a AQ Carbon HDMI when I received my PS Audio gear. 

It sounded good but didn't "WOW" me. I am particularly interested in DSD digital material and what can be extracted vs. vinyl. I spent a good deal of time researching different I2S cables and associated reviews. I was not willing to spend over $500 (even though I did with the RAL LOL). I have no problems spending money on cables as I have Kimber Power, KCAG, and Transparent Ultra V5 speaker cables. I just couldn't justify $2k for a short run of seemingly "silver" HDMI cables (AQ Dragon etc). Seems like the reviews I saw on the RAL CyroSilver were solid and your treatment of the silver seemed more technically sound. 

When I received the RAL I2S cable I was very impressed with the build. I appreciated your manual and the "warning" on twisting/bending. Prior to installing the cable I did a bit of listening with the current AQ Carbon setup. Soundstage decent, reasonably articulate instrument placement with good rendering of space.

 I then installed the RAL Prophecy. All I can say, anyone who doesn't believe cables make a difference don't have ears!!! The Prophecy immediately created a more natural presentation of the music with far greater detail than the AQ Carbon. Each instrument sounded "proper" in it's tone, weight, and timbre. Voices rendered with far better clarity and smoothness (even strong voices like Diana Krall or Allison Krauss). The depth of the sound was more closely that of the same analog LP (I am not an anti digital guy so not afraid to say this LOL). I could hear the layers of the recording and sense the outer boundaries of the recording studio. 

I could go on and on with what I have discovered over the past few weeks. I am a big believer in "silver" cables and you have reinforced that belief. I am sure I will be back for other offerings in the future. Very happy that I found Revelation Audio Labs.  Thank you so much for the kind addition of the faith based coin. I really appreciated that you are running your business on Christian principles. Congratulations!!  Merry Christmas!" - G.C.C. in Liberty, Ohio

"We have put approximately 200 plus hours on the cable. We really did not audition it during the first 100 hours so we did not receive any false impressions. This cable is extremely easy to understand what it does because it is very obvious. All other HDMI cables (dozens) we have tested sounded a version of themselves but nothing spectacular. The Revelation Audio Labs HDMI i2s cable is phase coherent and it sounds more accurate because it is totally in phase. If you listen to most HDMI they are out of phase. The detail is correct, staging is correct, depth is correct and midrange is clearer because the whole Revelation Audio Labs HDMI i2s cable is in phase. We have 2 HDMI inputs in our reference server so we could just do direct A/B testing at a flick of the switch and every person said what I am telling you after direct A/B testing.  If anyone asks we can now tell them we do have a reference HDMI cable." - Neill, Robert (Bob), President, Worldwide Wholesales, North American distirbutor for Rockna Audio

Recent unsolicited feedbacks from AudiogoN members (quoted by permission):

"Another amazing transaction and another amazing RAL HDMI cable. Sounded excellent right out of the box and it is improving every day. Shipping was super fast, even during the busiest time of Black Friday and Cyber Monday. BTW, this is my 3rd RAL cable. Both Ethernet and USB were beyond reproach and bested cables from AudioQuest (Diamond) WireWorld (Platinum), Shunyata (Sigma v2), SOtM (dCBL-CAT7), just to mention the few. I have a feeling that HDMI cable will do the same as I2S connection. Highly recommended!" - AudiogoN member arago 

“Revelation Audio Labs 
I2S/HDMI cable is the best I2S cable in my system and I have tried many others. It brought the music to another level immediately. I know it will get better with burn-in since this is my second cable from him. Btw I ordered the cable on Friday and received it on Monday! (Easter holiday weekend, no less)" - AudiogoN member cayman1000

"Perfect buying experience. Super fast shipping. I let this cable burn-in for 100 hours, before any critical listing. The cable connects my PS Audio Direct Stream DAC and transport. OMG! It's that good. The cable it replaced was quite good, but this is on a whole other level. It does the entire audio spectrum flawlessly. It conveys the most difficult musical passages with stunning resolution. Not sure cables get any better than this.” - AudiogoN member getheleadout


Quoting an e-mail from one of our esteemed beta testers of this completely new re-designed HDMI cable:   “I have now given a good work-out to your HDMI cable.  It is another winner – the best I have yet heard.  I compared it against my previous best cable, which is the top-of-the-line Furutech HDMI cable ($550 retail) that I had cryo-treated.  I’m using this cable between a Baetis Prodigy X server and my Marantz 8802a MCh pre/pro (with Wilson Audio speakers and Parasound JC-1 mono-block amps).  I now have the best MCh sound I have ever heard, so thank you very much.  Needless to say, we will be telling all of our customers about this cable, which is quite reasonably priced at $699.   Best, John    PS:  Andy Quint of TAS will have a chance to hear it when he visits us shortly; and congrats on your Golden Ear award and Stereophile Recommended Components.” - John Mingo, owner, Baetis Audio (




Other recent testimonials: 

"I would like to give you some feedback on your CryoSilver Reference HDMI cables, they are now my reference! The music when played through them just sounds more enjoyable with more clarity, life, air, weight, dynamics and without digital harshness. I was initially very skeptical of different HDMI cables making a big difference to the sound quality but now I have absolutely no doubt they do. Also HDMI cables that are ultra expensive do not necessarily sound better and I have proved this at least to myself as your HDMI cables came out best, and at less than half the price, compared to:

  • Audioquest Diamond

  • Wireworld Platinum Starlight

  • Nordost Valhalla 2

I have also tried the following and yours still come out tops: 
  • JIB Germany Silver Arrow

  • Silent Wire Germany REFERENCE mk3

  • Golden Sound Taiwan Platinum Silver

  • SAEC Japan Reference Series

  • Yena Audio Korea Carbon Reference

  • Purist Audio Design USA

  • Cardas USA

  • Transparent Cable Premium USA

I also tried good quality generic brands.

So as you can see I have indeed tested a number of HDMI cables.

Keep up the good work!
Thanks and best regards, 
J.H., Ireland"   

“I just wanted you to know that I received your HDMI cable and it looks great! Construction is top notch and I have it hooked up and burning in as I am typing this message. First impressions: WOW! I know it’s been said 1,000 times but it truly feels like a veil was lifted and I was hearing more of what’s on the CD. I have it connected between my PS Audio DMP transport and DirectStream DAC using their i2s ports. The cable it replaced was a WireWorld Silver Starlight 7 HDMI, their second from the top Platinum Starlight. The Silver, which was no slouch and sounded pretty good, or so I thought, until I installed your cable! The sound-stage has expanded, the highs are more present, bass is deep and tight, there is a clarity and blacker background and more presence to the music. All this and the cable is not even fully broken in yet! (about 24 hours of continuous play so far) I am hoping things will only improve with time. 

So, thank you for making such a beautiful and amazing sounding cable. It has brought my stereo system and enjoyment of it, to new heights!  With your HDMI cable, I have MUSIC!” - fabgear

"Just when I had about convinced myself I had been ripped off the HDMI I2S cable showed up unannounced. Even at 1st blush I am shocked at how good it sounds. This thing portrays S P A C E.  The soundstage is taller, wider and deeper than the Audioquest Diamond I have been using between my PS Audio Directstream Memory Player and my Directstream DAC’s HDMI ports. Still a bit early to make a good judgement about tonality, but this is a great bang for the buck cable.  UPDATE (2 weeks later):  I have listened quite a bit now and find myself rediscovering my CD/SACD/DVD audio collection. I am still floored to hear such an increase in available detail without brightness, glare, or sterility." - saddle3016

"Astonishing Sound Improvement - just a quick note to let you know that I have your 4-meter cable installed and have listened very carefully to some music I am thoroughly familiar with, and I cannot overemphasize the amazing improvement this cable has made to my system: I am hearing never-before heard details, especially low-level, sounds that were missing before installing your cable. The soundstaging is phenomenal. One more very important thing I forgot to mention: such precise image focus within the sound stage: you can ’see’ where everything is unless the sound of, say an organ, is intentionally manipulated to sound as if it is ethereal in the background (Yao-Si-Ting - Scarborough Fair).  Talk about being-there sound performance, I have it. This cable was well worth the wait and is never leaving as long as I’m alive. Thank you for providing such a phenomenal component." - M.P., Maine

“The reason I ordered your HDMI cable: I really appreciate your work and I am enjoying your Ethernet cable immensely. I compared it, in my system, against AudioQuest Diamond, WireWorld Platinum Starlight 8, Shunyata Sigma v2, SOtM dCBL-CAT7, just to mention few. It was the main reason I delayed this purchase for so long as I didn’t see (hear?) the need to improve anything. Now, audiophile bug was awaken again, so I will do some experiments comparing i2s in the HDMI format to i2s in the RJ-45 format. Looking forward to it. I am sure it will be another Revelation (pun intended :)) 
Best regards and keep up great work.” - A.A., Virginia, USA

"I am an owner of various Revelation Audio Labs analog and digital cables living in Hong Kong. I have been using his HDMI cables for two years. They are designed for transferring i2S signals according to Brad. After I found that they are superior over many other famous brands for transferring i2S signals, I tried to request to order an AV-compatible HDMI cable for connecting my Oppo 205 with Anthem AVM60 preamp. Brad guaranteed that his HDMI cables are AV-compatible. This is the truth. I can use it to transfer the bitstream signals from 205 to AVM60 smoothly. Later I also tried to use it to connect AVM60 with my new Sony A8H OLED TV. It can also successfully transfer 4K (up to 30P) HDR signals to my TV. The feature of Audio Return Channel (ARC) can also prove to work. Frankly speaking, I didn’t try to test its capability of transferring 4K 60P & 4K 120P signals because very few sources of UHD BD of these formats are commonly available. I wish that you might find my experiences about using RAL HDMI cables useful. Have a nice day!" - L.M.H.

Risk-Free 30 Day Audition Guarantee - try the cable in your system for a full 30 days - if you are not pleased, you may return the cable for a refund.  You may proceed with the confidence in knowing that no one who has tried the cable has returned it!

Fully supported and highly recommended by Steve Nugent of Empirical Audio for use in i2s audio applications (featured and sold on the EA web site), and John Mingo of Baetis Audio.

Crafted by hand with heart in the United States of America aside Florida’s Space Coast.

Designed for use as the i2s cable for respective appropriate equipment.  Quite naturally it serves as the supreme HDMI cable for the front end of your high end digital music system.  There is no other HDMI type cable built like it, nor is there a better HDMI type cable.  Period.  THE WORLD’S BEST.  WITHOUT EXCEPTION.  Our digital cable designs have even been commissioned by NASA for the reliable and lossless transmission of in-flight digital data!

Of course the cable you are using now, even if you paid a lot for it, is likely mediocre at best, and may actually be the weakest link in your fine music system.  Our cable finally enables the full sonic potential of the connected equipment that you paid for.

Completely new, updated design 

Although our previous design is still widely considered the gold standard, this completely new re-designed version takes audio performance to a entirely new level. Deep cryogenic treated 5N pure solid core CryoSilver™ conductors, Air Tunnel™ dielectrics, Mil. Spec. shieldings (layered solid and braided OFC shielding methodologies), and more.

To achieve this, we have to do what absolutely no one else in the world is doing.  As with all our cables, everything is done manually, completely by hand, involving numerous man hours of labor.  To start, within the oversized American-made PTFE Teflon tube that forms each discreet air dielectric, each hand polished conductor is carefully slid in the interior by hand.  Each of these tubes is then separately wrapped by hand with the shielding materials.  These form the sub-assemblies that are then fabricated into the eight-pole next-level assembly, then next installed within the CCIC™ (Conductive Carbon Infused Composite) outer jacket.  This process is the opposite of all other HDMI cable wire assemblies we are aware of.  They are all mass produced, machine made by the mile.   
Finest ultra high quality premium connectors. The new connector is extremely effective at providing superior conductivity, outstanding shielding characteristics, while its high mass reduces the unwanted affects of vibration.  It is extremely robust, rugged and well made for many years of trouble-free service, compared to the frail and delicate nature of typical HDMI connectors. The interior cavity of the heavy shell is potted by our injection process with an aerospace dielectric compound, augmenting the high mass, further reducing vibration and resonance, and increasing reliability through providing mechanical stress relief.

Please visit our web site for a full thesis on our design technologies, but as a brief synopsis, this cable features:     

• We start with bare single crystal five-nines (5N) ultra-pure solid core CryoSilver™ conductors – deep cryogenically treated in our exclusive vacuum cryogenic process. Silver is the most electrically conductive of all the elements, and our silver is not your father’s silver.  The raw, uninsulated wire used is made by a U.S. company that specializes in precision silver wiring technology primarily for advanced aerospace and medical imaging industries. Not at all what you find in other audio cables. No bulk cable is employed in any of our designs. That is simply because there is no bulk cable in existence that does what we need it to do.

• Air Tunnel™ dielectrics - no other HDMI cable in the world we are aware of employs air dielectrics.  Our unique, cutting edge technology makes it possible.  Each individual conductor pole is hermitically sealed to provide a consistent air dielectric impervious to saying ambient atmospheric conditions and contaminants.  Most common audio wire has extruded insulation, where the insulation material is in intimate and immediate contact with the conductor along its entire length. This forms the dielectric of the wire, which has a tendency to absorb and release energy to and from the conductor, and is a function of the capacitance of the cable. The occurrence of this phenomenon produces negative sonic affects. Dielectric constant measurements are used to determine the ability of an insulator to store electrical energy. Common insulator materials and their dielectric constants are Teflon (2.1), polyethylene (2.25) and polyvinyl chloride (3.18). The best practical dielectric is air, which has the near-perfect lowest dielectric constant (1.00059) next to a vacuum (which has a perfect dielectric constant of 1). However, there is one major disadvantage of an air dielectric in other audio cables. Although silver does not react with oxygen at normal temperatures, small amounts of sulfide, occurring naturally in the atmosphere, tarnish silver by the formation of silver sulfide on the surface of the metal. The dilemma of metal exposed to air is far more severe in the case of copper, which readily reacts to oxygen, resulting in copper oxide, that is not electrically conductive, on the surface of the copper metal. Most cable manufacturers that employ an air dielectric do not address the issue of their conductors being exposed to ambient air. Some designs actually employ a “porous insulation,” which seems acceptable in theory, until one considers the aforementioned affects on the metal surface. 

On the other hand, each discrete ultra-pure silver wire conductor, used in all Revelation Audio Labs cables, is hermetically sealed within its own oversized 100% pure virgin Teflon (PTFE) hollow sleeving tube, air being the best practical dielectric, and Teflon being the insulation material with the lowest dielectric constant (2.1). The interior cross section area of the tube is by design many times greater than the diameter of the wire, which minimizes the area of contact of the wire to the insulator. This system provides a huge air dielectric that is unaffected by ambient atmospheric conditions. The resulting characteristically low dielectric constant and extremely low capacitance is responsible for the high propagation speed of our cables.

• Progressive Hand Wrap discreet shields for each and every individual one of the conductor poles, critically  isolating each conductor/dielectric sub-assembly from all others within the array - eliminates EM effects, cross talk, eddy currents and other electrically induced detriment.

• Triple-layer solid and helically-woven stranded outer shielding 

• All shieldings are crucially drained to the source end ONLY - to carry absorbed internal and external EMI/RFI noise harmlessly away from THE MUSIC.  This technique provides isolation and avoids the undesirable practice of other HDMI cables of grounding the two connected units through the digital cable shields, which passes the absorbed noises from one unit to the other.

• Conductive Carbon Infused Composite (CCIC)™ outer jacket - this advanced technology material augments the EMI/RFI/EMF shielding of the cable.  The negative affects that static electrical fields and charges have on audio cables is well documented.  In addition to augmented shielding, crucially the Conductive Carbon jacket provides ESD (Electro Static Discharge) protection as it dissipates static fields and charges, also eliminating static electrical charges from accumulating in the first place, as their presence robs audio performance as it does with standard cable insulation.  There are a number of products on the market, accessories if you will, that address static electrical fields on audio cables.  Our unique design feature attacks the issue at the source through the proactive, preventative approach.  We have been performing tests and trials at length for some time, with phenomenal results, employing Conductive Carbon Infused Composite as the outer jacket material.  This material enhances EMI and RFI protection, but what this material provides above and beyond the protection of traditional shielding materials and methodologies is it provides Static Protection, guarding against the phenomenon of ESD (Electro Static Discharge).  The material absorbs and dissipates static electricity charge build-ups, which occur naturally on common non-conductive materials (i.e. cable insulation).  It is typical for these charge levels to be in the thousands of volts.  All areas of audio performance are enhanced by removing static electrical fields and charges from the surfaces of cables. This feature also improves performance by removing from your system surfaces that build and hold static electric fields.  Why do other so-called "cost-no-object" cable makers not use such a jacket material?  You tell me.   

• Finest ultra high quality premium heavy shell connectors. This robust connector is extremely effective at providing outstanding shielding characteristics, while its high mass reduces the unwanted affects of vibration.  The interior cavity is potted by our injection process with an aerospace dielectric compound, further reducing vibration and resonance, and increasing reliability through providing mechanical stress relief. This connector is extremely rugged and well made for many years of trouble-free service - as opposed to the frail and delicate nature of typical low-cost HDMI connectors. The fit and feel is solid, heavy and strong.  You know the connection is firm and solid as when you engage this connector into your equipment you have to press significantly and you literally  feel the substantial mechanical resistance as the connector engages.

• Aside from the fine imported connectors, all other raw materials and components of all our cables are manufactured entirely right here in the United States of America - not imported.

• Prior to shipment the cable is fully conditioned on our audiodharma Cable Cooker, and connector contacts are treated with Furutech NANO Liquid GOLD / SILVER / C30H50    

• 0.65-meter length (other lengths available - contact us)     

• Packed for protection in our beautiful custom handmade pouch with metallic company logo.

Other 'Prophecy' Digital Link cables Reviews and Testimonials:

Mr. Michael Murray-Robertson, an English classical music reviewer and symphonic ’cellist, apparently has a renown state-of-the-art listening enviroment, employing the dCS Scarlatti four-piece stack with this exact digital cable set (two Firewire cables, one AES/EBU cable, three BNC clocking cables) with Nagra tube amplification and Quad ESL is quoting his e-mail to dCS that he cc’d me:

Dear David, Dear Rav, 

As usual, it was good speaking with you on the telephone but I do look forward to your visit in person when this finally works out! Let’s hope my proposed dates prove convenient for you; Rav. My offer of a night here still stands!

As promised, I can confirm that the six digital cables for quadruple dCS Scarlatti from Revelation Audio Labs are outstanding. We made extensive comparisons cable by cable on original recordings at which I was present including Telarc: the results were obviously superior. 

Speaking as a classical music string player with forty years’ experience of live and reproduced music, I really felt that more of the spectrum was reproduced via these digital interconnects, the "grain" of upper harmonics revealed the individual colours of each instrument positioned precisely in an allotted space and given acoustics. Increased presence; dynamics were noticeable albeit without any aggressive or "shouty" aspect. 

The soundstage also widened; deepened. 

I identified the violin of Christian Ferras in the sixties and then again, played four decades later by Corey Cerovsèk in a different hall! Not the sound of any violin, rather that violin! From the "fluffy, horsehair on gut" sound of pianissimo strings to the liquid sound of a Cavaillé-Coll pipe organ, the endless nuances of the timbres made me simply want to just sit back and enjoy a moment in time with the performers.

In all honesty, I must warn that these cables are stiff; that undue bending for demos around the world might cause problems. Perhaps Rav could leave them in their pre-formed shape & pack them in foam for travel? And as I said, they do need time to ’burn in’ despite the generous time given for this at Revelation. I was unable to resist trying their balanced analogue and loudspeaker cables; the latter especially need time. 

The French say: ’you have to suffer to be beautiful’, and the English: ’patience is a virtue!’ 

I’m impatient but will not need to suffer again as I have found what I ’even closer approach to the original sound’.

I look forward to your news as promised. Bravo and best wishes, to all at Swavesey.


"Revelation Audio Labs cables have helped us reach an exceptional degree of untarnished communication of music, so I keenly recommended them here." - M.M.R.

Subsequent to employing our digital cable set, Mr. Murray-Robertson’s system is now fully wired exclusively with Revelation Audio Labs cables - from wall to speaker - all power cables, digital cables, analogue interconnects and loudspeaker cables.

Keep in mind that Mr. Murray-Robertson is not a high end equipment reviewer but a classical music reviewer, and as such does not technically write reviews for equipment.  Message me if you want his contact information as a reference.  He has not been compensated by us in any way.

“I’ve had a chance to let my new Revelation Audio Labs ’Prophecy’ CryoSilver Reference DualConduit USB 2.0 Digital Link Cable break in for 250 hours, and my music playback has been completely transformed and considerably better sounding than it did when the cable was new, and amazingly better than using a standard upgrade USB cable! When I broke in the RAL ’Prophecy’ i2s Bus cable in on my Audio Alchemy digital front end back in 2004, it brought a substantial improvement in sound quality, but the sonic improvements that your RAL ’Prophecy’ Dual Conduit USB Cable has manifest brings a much deeper level detail, a more accurate tonal correctness and authentic imaging than I have ever heard before in over 30 years of seeking improved sound quality from my audio system.

Thank you so much for creating this amazing USB cable which has brought my music playback alive in a way that I could only dream of before!

I would be honored if you would like to use any of my comments about the amazing Revelation Audio Labs ’Prophecy’ CryoSilver Reference DualConduit USB 2.0 Digital Link Cable, because you have created the one and only USB cable that makes a wonderful improvement in sound quality where everyone said it could not be done, which to me qualifies it as a sonic miracle! I came across the $3,500 Locus SinoSure v2 single conduit USB cable the other day and I noticed that they had filled this huge cable with very complicated wire geometry in an effort to do what you have so simply and much more effectively done with your innovative Dual Conduit design.    —Stephen W. (Sept. 2011)”

REVIEW: 13W3 i2S connector for Muse Transport & DAC 

I bought the Muse Model 8 Transport and Muse 296 DAC over 5 years ago and have enjoyed its analogue-like performance afforded by the i2S cable. I always felt that the ’weak link’ in this system was the stock Belden 13W3 cable provided by Muse- I thought the performance would be further improved with a higher quality i2S cable. After trying several times to locate a replacement, in July of ’04 I was referred to Brad Vojtech of Revelation Audio Labs thru Audio Asylum ’;@ }. Brad told me he could build me this cable, but as it would be his first of this type using 13W3 connectors, it could take a while to find suitable quality connectors that he would be happy with.

Brad told me the wait would be well worth my patience. He was right.

Revelation Audio Labs describes the cable as ’featuring state-of-the-art mil-spec CONEC connectors, cryogenically treated ultra-pure (5-N’s) solid silver conductors, air dielectrics, Teflon insulators, multi-layer/multi-material EMI/RFI shielding and proprietary Ceramic Micro-Bead Conduit. Meticulously artisan-built, hand-crafted in the USA, designed to be the most robust, advanced, exotic, and musical i2S audio cable in the world. The materials and construction techniques are world-class, aerospace quality.’

They aren’t kidding...

I received the completed cable in November of ’04. I was very impressed by the quality of construction and materials used, clearly superior in solidity and appearance to the stock cable. But the proof is ultimately in the performance, so out went the stock cable, and in went the Prophecy...

Fresh out of the box this cable is truly a Revelation. While Brad recommends a 100 hour burn-in time, the sound was improved across the board. The bass was the most noticeable- bass seemed to gain at least a 1/2 octave deeper, with much improved "push"/extension, detail speed and more ’bounce’ — there was more energy driving the music, equivalent to a major component upgrade. The soundstage was deeper and wider, with a clearer, more stable presentation and imaging of instruments, evolving in free space, and a better separation between individual instruments. Midrange and highs improved with a more individual ’ease’ to the music. Voices were even more lifelike sounding like complete bodies with chests, not just mouths singing. Sounds I never heard before on very familiar albums were heard for the first time, which added to my overall involvement and enjoyment. Over time, the sound became even smoother, with a more natural ease and musical flow. Bass tightened up more. Where I previously thought I needed to improve the bass response, which was the weakest part of my system, I no longer feel the need to do so.

This cable has made a wholesale improvement to the enjoyment and overall musicality of my system. If you own a Muse transport/DAC combo with 13W3 i2S cable, this is a no-brainer — RUN, don’t walk, call Brad Vojtech at Revelation Audio Labs, and order this cable today. Your ears will thank you.

Regards, Gary H.

(By the way, this 13W3 cable can also be used with Sonic Frontiers digital gear.)”

“The cables (Prophecy i2s and Parable power cords) arrived today. I hooked them up and there was an immediate sense of more information and fine detail of greater image specificity within a space. This is an across-the-board system improvement that would have required thousands of dollars of investment in new components. I will now try to resist the temptation to listen while they cook for the recommended burn-in period.”     Thanks, A.J.

“Talk about ’Bang for the Buck.’ This has got to be the best (money) I’ve ever spent. I could go on and on about just how great the cable is, because it truly is amazing, but I’ll make it short by saying that I agree with everything that you — and the reviewers mentioned in your product description — had to say about the cable. Far superior to the Audio Magic cable, no comparison, not even close. IT’S AS IF I WENT OUT AND SPEND $THOUSANDS$ ON A BRAND NEW SYSTEM. Incredibly musical. Anybody that’s using the Perpetual Technologies P1A/P3A combo will never know just how good the combo can sound unless they’re using your cable. Thanks for making available such a great product for all of us to enjoy. God Bless You.”

“As far as reviews, I’m not into the jargon of reviewers and don’t want to use terms I feel are vague (what is ’grain?’ is yours the same as mine?). I HAVE heard a good deal of live music over the years, in venues ranging from my living room, to small clubs, to theaters to stadiums. I try to compare what I hear from my stereo system to that collective musical memory. By that standard, adding the Revelation in place of the Audio Magic Mystic clearly resulted in more musicality from my system — most obvious to my ears. My system: Musical Design T1 CD transport; Perpetual Technologies 1A and 3A processor and DAC; Sound Valves VTP-101i preamp; Blue Circle BC-28 power amp; Tyler Acoustics Linbrook Reference System speakers.”

“I’m quite satisfied with your (Prophecy i2s and Parable power cord) cables. Burned them in for 106 hours, then put on discs to which I’d recently listened, and was amazed by the improvements. I first noticed improved bass: more defined, cleaner, and tighter. It’s as if the cables shaped a diffuse beam into a tight signal. (Note: my speaker cables and interconnects are no slouches.) Next, I sensed a wider and deeper soundstage. One of the strengths of my system (and most satisfying to me), I believe, is its ability to portray a three-dimensional soundstage. With your cables, the soundstage expanded, especially in its depth. This expansion, by the way, is by no means overwrought — on the contrary, it’s in the realm of bigger is better. Live recordings particularly benefited from the introduction of your cables into the system. I clearly detect a better portrayal of the stage, whether it’s in a smoke-filled club or a huge stadium. In fact, REO’s ’You Get What You Play For,’ my ultimate system-testing CD and my favorite live album, never sounded better. ’Golden Country’ filled the room wall-to-wall. I momentarily thought I was listening to a multi-channel system. This pleases to no end. Layering of instruments and vocals is much improved. I can now clearly make out background vocals, for example. This was startling on Alice Peacock’s excellent self-titled CD. Before your cables arrived, background vocals were muddled a tad in the mix — I had to strain to make out the words. Now I can make out the words sans strain. Plus, on many live recordings, individual voices in the crowd, singers bumping microphones, guitarists unplugging from amps, drummers busting sticks, are all rendered more vivid, making the recordings more lifelike, and listening to them way more enjoyable. Finally, I like the fit and finish. And I was right: my eight-year-old son likes the color. I do, too. I wish to emphasize that I am pleased with the improvements your cables bring. I wish you continued success.”    — M.B. 

“Revelation cables are in the house...thanks in large part to the rave reviews of a few of the guys on (the Perpetual Technologies/AV123) forum (you know who you are) I picked up the i2s and power cables used. Already having a $150 Camelot i2s cable (which came with my PT gear when I bought it used), I was pretty reluctant to buy these... seemed like a lot of cash to drop for what was likely (I thought) to be a minimal upgrade. Well, I was wrong. I don’t know how they do it, but these cables make an enormous difference. There was distortion before that’s just plain gone now, and the impact of that on the sound of the system (particularly when it comes to ’micro-detail’) just can’t be overstated. Maybe it was interference on the power lines running from the Monolith? I have no clue, but I do know that these things should be required equipment if you have the PT gear. So now I have the absolute Cadillac of Perpetual Technologies hardware (Modwright Monolith PS, P1-A, all three Revelation cables, and a Modwright Level II P3-A) and I’m wondering, how much better could Redbook playback possibly get?”

“After allowing sufficient time for burn-in, I have done a lot of serious listening to the Revelation Audio Labs i2s in both i2s direct and indirect mode and have concluded overall that the Revelation Audio Labs is indeed an excellent interconnect. To date the only head to head listening tests I’ve done is with the Audio Magic Mystic Reference i2s, and although I have not yet broken out the results, it is obvious that the Revelation i2s is the clear winner.”    — P.W.

“The cable had about 24 hours on it when I sat down to listen last night. It gets better and better...and I loved it out of the box. In my system, there is no doubt about it’s superiority to the Audio Magic. It takes the upper midrange/treble glare out, is smooth, non fatiguing, revealing, detailed, and balanced. Problems I had attributed to other aspects of my system, were in fact, the Audio Magic. I eagerly await its full burn-in. This cable is a WINNER. It brought that ’I want to hear this, now I need to hear this, etc.’ I would like to contact Perpetual Technologies to let them know they need to include or offer this with their products — as one hasn’t heard what they are capable of until this i2S is part of the package.”    — R.T.

“This thing is incredible. Separation of the frequencies becomes better. Imaging becomes more solid and precise. Detail increases and everything just sounds more crisp and real. Bass becomes more solid. I now understand why people have raved about it. For the price it is a no-brainer IMO.”

“I now have about 48hrs on the cable and it gets better and better. It is the most significant improvement in my system in as long as I can remember.”

“How do they sound? ’WOW’ is all I can come up with. Huge improvement in soundstage and it definitely took the digital edge off.”

“The performance of your Prophecy i2s cable was HEAD, SHOULDERS and TORSO above the other two i2s cables that I auditioned (0.5-meter Audio Magic Mystic Reference, $149, and 1-meter LAT International, $99). It allows the highly detailed and refined digital signal, transmitted through the Siltec Golden Ridge digital cable and Perpetual Technologies P-1A 24-bit interpolation engine in my system, to come through completely unscathed. The musicality is unprecedented in my experience; I now no longer listen to the sound, but can get totally into the music. REMARKABLE!”    — J. 

“I’m smiling right now listening to (a favorite recording). SOUNDS FANTASTIC!!!. Absolutely a night and day difference...What!? They will sound better when they break in — can’t wait! Your cables have definitely increased my listening pleasure.”     — B.K.

“I like your Prophecy i2s and you will NOT be getting it back! It has a body and a clarity that my Mystic Reference cannot match, which surprised me because I had always considered the MR to be a solid performer. By comparison the Other Cable sounds uncultured. But there’s worse! I also run an Mystic R i2s from my Audio Alchemy DDS Pro to the PT P-1A and when I put your Prophecy between the P-1A and P-3A, the transport to P-1A cable (Mystic) was exposed as being very harsh (you following me?!). Why this should be, I don’t know, but I had to put a AES/EBU after the transport to eliminate the digital nasties. This is good news for you, because I now have to audition a 1-meter Prophecy! I would also like to hear your Power supply to P-1A and P-3A cables also... this is a place that I’ve always thought of as a potential source of electrical interference. Thanks for a great product.”    — B.G. 

“I believe you have the best i2S cable out there.”

“Hello Brad, I would like to thank you for your S/PDIF digital cable and how it has transformed my system. The cable took a few days to settle in, sounding a bit thin and analytical at first. After the burn in period the sound was transformed and I could hear the true potential of my Perpetual Technologies P-1A/P-3A DAC combo for the first time. I think that anybody who has the RAL ’Prophecy’ i2S cable should seriously consider using the RAL S/ PDIF from their transport to the P-1A. I am not exaggerating it was like upgrading a piece of equipment it was that good from high frequencies to bottom all seamlessly integrated and sounding neutral, true to the timbre of the individual instruments. The speed of the cable is also amazing so that micro details in the recordings that I didn’t even know were there now add to the sense of immediacy and realism, of musicians playing real instruments. You have to hear this for yourself as I was a little skeptical at first thinking merely that the cable would change the color of the sound rather than transform the whole musical experience of the system as it did. Given that Brad offers a no quibble 30 day return policy, as you Americans say, trying this cable in your own system is a no brainer. ”    —Alex, UK

“I received the cables today. They are OUTSTANDING!! You should advertise the power cables more. The I2S is much better than the original. You have a great product and you should be very proud.”

“Music flowed, far more musical than the Mystic i2s. God bless you and yours. With such a great product and customer service, your business should prosper. I surely hope it does.”

“Your cable has arrived, and is, indeed, already a noticeable improvement over the Mystic Reference...I’ll review it when the burn-in seems to have completed.”

“Just gave the cable its first listen. It is FAR more musical than the Audio Magic.”

“I think the cables are a wonderful improvement. Right out of the box it gave me incredible holographic imaging and wider soundstage.”

“I finished burning in my Prophecy i2S digital link cable, and then sat down to do a serious A/B comparison with a cable I made myself from some VH audio cotton insulated silver wire. I thought sure my homemade cable would be just as good if not better, since it was utterly minimalist in design. I have an associate’s degree in electronic systems technology, and have been an electronics technician in the U.S. Air Force for almost 18 years — all my training and experience tells me a digital cable should have no effect on audio whatsoever. I should be able to stick almost any conductor in the circuit and it do just as well as the most expensive digital cable, but that’s not what I heard.  Realizing that human nature would not allow me to be objective, I asked my wife to listen with me. She didn’t know which cable was which, yet our observations were identical.  My cable had a slightly grainy quality which I would have never noticed if I hadn’t had yours to compare it against; yours simply sounded smoother, but paradoxically, there was more detail. And more presence. It sounded like I was a little closer to the musicians and singers.  So now I’m mad. I was all proud of myself for designing this cable that would be just as good as your expensive snake-oil cable, and then I could send your cable back for a refund and laugh at you all the way to the bank. Instead I’m keeping it and crawling off to lick my wounds. And try and figure out why mine didn’t sound as good.”    —C.M.
