Home Computer Audio Asylum

Music servers and other computer based digital audio technologies.

I think that *might* be true

I have the Ayre QB-9 DSD which is galvanically isolated (whatever that means!) and produces its own USB power independent of the computer. The computer-side tweaks I've tried have made little to no difference in SQ.

From Computer Audiophile: "Connected to most DACs I can easily hear all kinds of garbage as if five refrigerators were sharing the same power outlet with my audio system. However, when I connect this electrically noisy computer to the QB-9 DSD I hear silence through the speakers. "

But I've read reports from at least one other QB-9 owner that claimed the QB-9 is sensitive to computer-side tweaks. Go figure.
