This thread gave me the idea of trying to connect my computer/DAC directly to my power amp and use the volume control in Amarra. It worked and sounded great. I don't see why doing volume control in the digital domain should degrade sound if it's done at a high enough bit depth. It kind of made me nervous though, and I won't be doing it on a regular basis, as one slip of the volume control or an accidental reset to maximum and it could be all over for the speakers.
