"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 a 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 umbilical 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 umbilical cord. The sound is clean and in fact, the cable contributes much in opening up the soundstage And brings up micro info which was 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 were 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 power cords and a line filter). So, Thank you very much.....I will recommend your products to every person I know! Take care of 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  

QUOTING:   "I finally connected the cable to the system. the first impressions are very positive: a high-quality product and certainly a remarkable musicality. The improvements made go in the direction I hoped for. If you are interested in having more details I am happy to update you. I will be happy to leave positive feedback and promote your brand here in Italy. Forgive my poor English." - P.D., Italy   END QUOTE

We anxiously welcome your inquiry. 

Features DualConduit™ design, augmenting isolation and separation of the crucial analog power supply voltages from the digital control signals within the cable. The power and grounds for the analog circuitry are enclosed in their own dedicated cable conduit, and the digital power and grounds are enclosed in the other dedicated cable conduit. This eliminates the undesirable effects inherent in a standard cable wherein all conductors are parallel in intimate near proximity, each conductor affecting the other conductors within the typical single array design.  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 website 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 

•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, crosstalk, and eddy currents •Triple-layer solid and helically-woven stranded outer shieldings 

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

•Dual Ceramic MicroSphere™ conduits - another proprietary design feature - absorbs and dissipates both internal and external mechanical and airborne 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 are 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 the 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 effects 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 from 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 Furutech NANO Liquid™ GOLD / SILVER / C30H50 

•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: 

"The 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 preamp upgrade. - Rich, U.K." 

"Early 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 an increased resolution of details and more refined mid and high frequencies. It is indeed good value for money. I have demo'd 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."
