Bryon... I used it initially as well and thought that at 100% it would have a gain of 1 and all is fine. However, above 75% I could hear distortion. It was overdriving the DAC. Also when set to Fixed the volume is at 60% - 70% of the variable mode. I called Sonos a few minutes ago and they also recommend the Fixed mode when going into a DAC.
I also have two of the Sonos S5 powered speakers and they are just fine with the volume control. Bought them for my wife. ;)
