Revelation Audio Labs CryoSilver Reference USB cable, Type A to Type B 2.0






Brand New 'Prophecy' CryoSilver Reference™ DualConduit™ USB digital link cable - featuring dual Type A male plugs on the source end, terminated to a single Type B 2.0 on the other end (also available: dual Type C male, and single Type A male versions available - please enquire).


The only USB cable on the Stereophile magazine 2023 Recommended Components List.



Cable features deep cryogenic-treated 5N UltraPure solid silver conductors, air dielectrics, transparent pure PTFE Teflon isolators, discrete shielding for each pole within the array, and Ceramic MicroSphere™ Conduits, with independent power and signal cable runs.

The USB cable employs our innovation - a ground-breaking structure — DualConduit™ — separate cables for the power and signal lines.

The cable actually has two design-specific cables each with high-quality USB Type C connectors for connection to your source. One Type C connector and cable handles only the delicate digital music signal; no corrupted computer power runs through this cable leg. Its design is that of a ultra high-end digital audio cable. The other Type C connector and cable handles only the DC power; its design is that of an ultra high-end audio power cable — the digital music signal does not run through this cable leg. On the other end of the "Y" shaped cable is a single high-quality USB 2.0 Type B connector that connects to your processor.

Remember, if your equipment has legacy Type A receptacles, or a single Type A receptacle or single Type C receptacle, just let me know - I offer those options also.

It is widely known that the radiated magnetic field and any radiated noise from power cables affects signal cables and corrupts the quality of the delicate music signal when a signal cable and a power cable are installed in parallel or are in close proximity with each other. However, virtually every Firewire cable available on the market has the signal line and power line in one cable together — we can clearly understand how sound quality is deteriorated by such architectures.

Some high-end USB cables have independently shielded signal and power lines. This is an improvement over the typical configuration, however, these two lines are in still parallel and in intimate proximity in the same cable and induced affects are constantly causing noise reflections inside the shieldings, which will significantly damage sound quality. Moreover, the power supply lines in USB cables transmit a large amount of electrical interference (grunge, pollution, noise) and that is passed on from the power supply buss of the source equipment (computer). This "corrupted power" seriously degrades the quality of the digital music signal being transmitted and therefore, audio sound quality is greatly reduced. Although our previous design features discrete shielding for each conductor pole, which is superior to most cables on the market (a feature also included in this latest design), which addresses this issue and is vastly superior to the typical USB cable, our DualConduit™ design offers the ultimate in isolation of the signal lines from the power lines. Our latest-design USB cable is equipped with two independent cables consisting of a shielded structure with a 100% shielding effect obtained by using heavy solid and silver-plated copper stranded shields. This is the only USB cable which is successful in stopping noise interaction between the power and signal lines.

There is another profound benefit of the DualConduit design. For some processors — in particular processors that have their own internal power and therefore do not require USB power from the connected source (PC or Mac) to operate — the power leg may be required to begin the handshake between the DAC and the source, but once the USB driver has loaded, the power leg on these processors is no longer needed so you are free to entirely disconnect the power conduit. This means less noise from the PC or Mac, lower noise floor as a result.

For those who have a limited number of available USB ports, the DualConduit™ USB cable is also available with a single Type A connector on the input end, or a single Type C connector on the input end. Please specify.

Here is an unsolicited testimonial from one customer:


"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)


Revelation Audio Labs was chosen by Stereophile magazine for their 2023 Recommended Components, which makes it nine consecutive times (also Fall 2022, 2022, Fall 2021, 2021, 2020, Fall 2019, 2019 AND 2018).

Revelation Audio Labs was also chosen by The Absolute Sound magazine for the 2018 Golden Ear Award, published in their September issue (#286) - one of only three cable brands to be awarded the 2018 Golden Ear, the only digital cable chosen, and the only cable under the four thousand dollar ($4,000.00) price point.  Note: since NO CABLE was chosen for the 2019 Golden Ear Award, we remain as one of the last few cables to receive a Golden Ear Award


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 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 USB cable for respective appropriate equipment.  Quite naturally it serves as the supreme USB cable for the front end of your high end digital music system.  There is no other USB type cable built like it, nor is there a better USB type cable.  Period.  THE WORLD’S BEST.  WITHOUT EXCEPTION.  Our digital cable designs including USB have even been commissioned by NASA for the reliable and lossless transmission of in-flight digital data!  NO OTHER HIGH END AUDIO CABLE DESIGNER CAN STAKE THAT CLAIM ! ! !

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 USB 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 USB 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 USB 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 USB 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. These robust connectors are 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 USB 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    

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

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