Revelation Audio Labs has been chosen FOUR TIMES in a row by Stereophile magazine for their 2020, Fall 2019, 2019 AND 2018 Recommended Components, published here:  


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 currently remain as one of the last few cables to receive a Golden Ear Award.

QUOTING: "Hi, let me make it clear..the umbilical-cord does have an effect on the sound reproduction seems like my préamp just waking-up from coma ... since it is not fully broke in totally dare I say the best is yet to come...thank you for the work you put into your u.cord. Update - forgive me if it took me all that time to give you my thoughtS concerning My préamp cadenza umbilical cord. I had to wait till it reaches its full Break in...and I think it still will get Improve while the time goes by. Your umbilcal cord makes the whole System disappear and let room Only to music...we were afraid to disappear in our turn... :-) It an exceptional improvement The whole blabby skin effect disappeared ...your umbilical cable Cleans up the music in a way You could wonder if you're clean enough to listen to it....thank you. UPDATE: no doubt about is a reality at least with my system...all started with a hard sound at the beginning and after few months the sound became soft and pleasant and I felt necessary to convey my feeling regarding your umbilcal cord. The sound is clean and in fact the cable contributes much in opening up the sound stage And brings up micro info which were Hidden...when I listen at night It gives the impression 'ghost band invasion are playing music'...believe it or not and as I said it will soften as the time goes by. Yours sincerely, A.C., Paris, France END QUOTE 

QUOTING:  "How are you my friend?

I receive my umbilical 6 days ago and when I see the cable, (within) the velvet pouch, I don´t believe the quality of the product!!!!!!

Of course the sound is at the same level, after 5 continuous days feeding my Pass Labs XP-20 preamp the results was spectacular!!!!!!!

More bass impact, really better mids and highs, A LOT OF DETAIL!!!, the focus of the voices are perfectly in the center of the loudspeakers and the texture are amazing (I have the singers performing for me in my living room!!!! NO JOKE!!!!)......summarizing, the best and most notorious cable I ever had (and I have totally wired my system with Transparent Reference XL MM and MM2, including the powercords and a line filter).

So, Thank you very much.....I will recommend your products with every person I know!

Take care you and your family, (it) is a pleasure for me to deal with very nice people like you.

Best regards from Argentina friend, Pablo Reggiani" END QUOTE


0.75-meter Revelation Audio Labs 'Passage' CryoSilver 
™ DB-25 umbilical power cable featuring Ceramic 
MicroSphere™ DualConduit™ technology.     


Crafted by hand with heart in Palm Coast, Florida, the United States of America.



A state of the art upgrade power umbilical cable for use between
the outboard power supply and main chassis of Pass Labs XP preamps, McIntosh
C500 preamp, Resolution Audio Opus 21, as well as other equipment using the
DB-25 style (25-pin D-Sub) connector.  DB-15 version also available for Viola Audio Labs, ClearAudio, Sim Audio, Oracle, as well as other equipment using the DB-15 style (15-pin D-Sub) connector (please check your equipment before


Features DualConduit™ design, augmenting isolation and
separation of the the crucial analog power supply voltages from the digital
control signals within the cable.
Employing the best Military Specification
Amphenol male-to-female DB-25 connectors and high mass heavily shielded solid
cast metal shells.    


The umbilical cable upgrade far surpasses the performance
enhancement of a complete component replacement.


A high-performance, no-compromise umbilical power cable which
merits use with your fine equipment. A phenomenal upgrade from the stock
umbilical power cable. The designers of your equipment exploited the
operational benefits of housing and isolating the power supply components
and circuits in a separate chassis.  The power supplies are designed to do
an excellent job of providing plenty of clean power.  Unfortunately, the
equipment designers fail to assign a high priority to the design of the stock
cable, do not task the same painstaking care and attention to this aspect of
their product, and therefore do not exercise high end audio power cable design
disciplines into the stock umbilical cable.  The stock cable is admittedly
mediocre at best, and may actually be the weakest link in your fine music
system. Now you can finally deliver that quality power you paid for to the gear
completely unaltered, uncorrupted, unpolluted and unhindered. This upgrade
truly optimizes the performance and realizes the full sonic potential of the
connected equipment. The cable is in use by many music lovers worldwide. You
will be utterly astounded when you hear the huge improvements this cable makes
to your music! 


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


•Deep cryogenic treated five-nines (5N) ultra-pure solid core CryoSilver


Big Air™ dielectrics 


•Transparent Teflon isolators 


Progressive Hand Wrap™ discreet shields for each
critical conductor pole, isolating each conductor/dielectric sub-assembly from
all others within each array - eliminates EM effects, cross talk, and eddy


•Triple-layer solid and helically-woven stranded outer


•All shieldings drained to the power supply end only - to carry
absorbed internal and external EMI/RFI noise harmlessly away from the


Dual Ceramic MicroSphere™ conduits - another proprietary design feature - absorbs
and dissipates both internal and external air borne vibrations, resonances and
microphonics.  Ordinary high-end cables are a major path for mechanical
vibration to enter sensitive audio equipment.  In addition, the effects
resonance has on the performance of audio cables themselves is well documented.
 Audio frequency vibrations induced into the cable may create a state of
microphony and transduce physical resonance into electrical resonance,
polluting the audio stream.  However the most harmful mechanical energy is
actually generated internally by the electrical components comprising the audio
equipment circuitry, consequently occurring precisely where the delicate music
signal resides. These vibrations produce phasing errors that slur and garble
the music, diminishing resolution and coloring harmonic equilibrium. To
combat this phenomenon, the conduit of this cable is filled by a special
process with proprietary Ceramic MicroSpheres™ (patent applied for,
Revelation Audio Labs, Inc.), developed through and supported by a number of
relevant NASA White Papers dealing with crystal lattices, expressly to defeat
this menace to faithful music reproduction. This results in a cable that
is virtually immune to the propagation
of micro-vibration, and minimizes parasitic vibration of the equipment power
supply and audio circuitry.  This could be one of your most valuable weapons in
your isolation arsenal.


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. 


•Highest quality Military Specification Amphenol connectors with
heavy solid metal shielded shells.  


•Prior to shipment the cable is fully conditioned on our audiodharma
Cable Cooker,
and connector contacts are treated with Walker Audio E-SST
Extreme Super Silver Treatment
contact enhancer    


•0.75-meter length (longer lengths available)    


•Packed for protection in our beautiful custom handmade heavy
double-layer Blackberry Velour pouch with Velcro closures, company
logo embroidered in metallic purple.  Connectors are protected
with Caplets.

A few more recent testimonials:

DB-25 has had about 60 hours & is excellent! Even after the first few
minutes I could hear it was special...! It compares to a pre amp upgrade.
 - Rich, U.K."


impressions are good!  What I notice most is an increase in low-level
detail - big time!  As I spend more time with it I'll be able to say
more about it.  - Howard, U.S."


"The DB-25 umbilical cord has indeed
brought improvements to the performance of my Pass Labs XP20. I perceived
increased resolution of details and more refined mid and high frequencies. It
is indeed good value for money.  
I have demo'ed it at home to several of my friends most of
whom did observe the improvements. One friend who runs an XP30 knows your
website and is giving the matter of two umbilicals his serious consideration.
 - Patrick, H.K."
