Current chain here is: JCAT USB interface card (powered by JCAT Battery PSU) -> TotalDAC D1 USB cable/filter -> uptone Audio USB REGEN (powered by 12V BoTWS linear PSU) -> Devialet.
Before I bought the TotalDAC D1 USB cable I owned the Kingrex Unanimous Ucraft USB Y cable and a Kingrex U power which is a battery injecting power into the power leg of the USB cable. The TotalDAC cable however was better in every way in my system.The Devialet doesn't use the USB power, or better said it's only used for the detection of an active host and handshake process. Also the Regen disconnects the 5V and replaces it with it's own clean power.
Since I own the Regen I feel there may be some redundancy in the chain but I haven't bothered yet with selectively removing parts from it to confirm this (or not).
Hi,
This hobby is all about personal taste. I had both Kingrex and totaldac usb filter cable in my system. Didn't like both. Because I use Kondo Japan silver cables everywhere, I am very sensitive about the "air feeling" in my system and they both reduce a clarity . And the batteries have to be implemented very clever. I also dont like the sound of battery PS. After all my research I will stay with this solution. "Y" cable, good 5V PS... nothing else. Pure signal and SILVER chain. Even if 5V is used in Devialet for the detection of an active host and handshake process I can hear the difference in 5V PS. And be verrrrry careful about battery suplies.
regards, Hrky
