The heart of the new 'Epitome+' USB chain - major step up in SQ when using this cable on the DC-30W LPS and DAC.
"The major improvements comprise a special power cable to feed the single DC-30W. I have had a long and extensive experience with power cords - over 50 or so different ones over the years. Some of my favorites the C.P.C.C. Top gun HiCurrent, Synergistic Research X2 Reference Active, SR Tesla, Nordost Valhalla, Shunyata Power Snakes, Shunyata Venom, Cerious Technologies Graphene Extreme, Tellurium Q Black, etc..."
Some of these are just insanely expensive - like the $3000 Nordost Valhalla's. They all sound different. My previous best sounding power cord was the amazing Cerious Technologies Graphene Extreme - I discovered and posted about back on the XU208 thread. Around $350 it was an audio bargain and become a very popular cable as folks tried it.
With my experience with the importance of EMI/RFI and shielding I wanted to attack that issue with a cable that addresses those issues. A power cable can pick up all kinds of noise - and the worst kind - high frequency noise that is very hard to filter out. This comes from all around radio and WiFi transmissions, capacitive coupling with the houses wiring, and other electronic devices, etc...
Quoting Caelin Gabriel, President - Shunyata Research Quote: "...Your dedicated power lines, rhodium plated outlets and large gauge wires in the wall in no way immunize you to power line noise. Power line noise is picked up from radiated electromagnetic waves all around you. This includes AM and FM radio, wifi, cell frequencies and the list goes on. Furthermore noise reduction is always "localized". That means that just because you have a power conditioner that reduces conducted noise does not mean that the noise doesn't re-introduce itself farther down the line. So if you have some form of power conditioning at the electrical panel, the radiated noise will be picked-up by the in-wall wiring that acts like an antennae. This means you WILL have noise on the power line at the wall outlet. This is why we talk about the "distributed power conditioning" approach to noise reduction."
Quote: ...For example, using the Enteq at my house I found that I had a very strong radio station being picked-up by my upstairs power lines. I also could hear the very distinctive sound of LED lighting noise pollution. Quite insidious actually.
After much experimentation I believe I have come up with an excellent solution that uses both active magnetic EMI/RFI reduction and passive thermal dissipation. The cable while having a tinned copper braided shield - the shield is not connected to ground. The reason many shielded power cords have not sounded great - these shields can act as capacitors and build charge - releasing it into the ground. A unattached copper shield with dissipate EMI/RFI energy thermally in a passive fashion.
The wire is a special heavily silver plated copper 10awg - teflon shielded - with the three wires twisted to min capacitive coupling. There are four layers of shielding - with two between the silver wires and the copper shielding - and that copper shielding is designed to be lose and distanced from the inner wires. Finally a solid one piece shrink wrap as added protection. I hate these cables with that delicate nylon mesh on the outside. It always seems to come lose at the terminals and gets holes in it from snagging. The wires are chemically treated with Nordost ECO 3, and the Wattgates with ProGold GxMD contact enhancer and oxidation inhibitor.
And about the connectors - Wattgates of course. Not cheap at all! But worth every penny!
Wattgates cyro process is one of the best:"
Quote: "Wattgate Cryo Treated Products After ten years of researching cryogenic technology, we now cryogenically treat our Wattgate line of products in house. Years of testing different methods and processes within the cryogenic field have led us to develop our own optimized approach. Our method of Deep Cryogenic Treatment(DCT) is of the indirect or dry type. A specially optimized cycling method is employed to achieve maximum benefit for our products. With the indirect or dry process the parts are never subject to direct contact with liquid nitrogen, avoiding thermal shock to the materials. The process takes between four and five days to complete. We have truly enjoyed the sonic results of this process, we think you will too. Look for the Cryo Treated logo to be sure that you are getting Cryo Treated Wattgate products."
