Hi sandyk Thanks for your reply. I'm not sure I understand exactly, but as I interpret your note, you only supply your BR writer with data from your computer and use a separate power supply for the device itself. Interesting. Gives me confidence to keep exploring. I'm just not sure about the sensitivity of a DAC and the possible consequences of this approach.I guess the smart thing is to talk to the manufacturer. I'll keep you posted. Thanks again.

Greetings, After much searching around on this forum and others I have not been able to find an answer to the following issue... I have recently joined the audiophile world and realize that there are many issues that can affect the sound you end up hearing. One objective is to remove sources of interference that do/can damage the purity of the source audio signal. I've been considering which USB cable I should use with my DAC. Many people talk about improved sound using cables that separate the power from the data lines. That makes sense to me. But here's what I don't understand... My DAC has its own power supply. Therefore, why not use a USB cable (if one exists) that delivers high quality data streaming only i.e. Has no power transmission capability? In other words keep as much power interference from one's computer out of the DAC as possible. Is there some kind of timing signal perhaps that comes down the USB power wires in the cable? Thoughts and explanations would be most welcome. Many thanks, Pix
