I've not experienced that before, not sure what could be causing that problem.

What colour plastic sleeve does the DAC have?

The plastic sleeve is transparent.

I've been doing some experiments and I've found a combination that is sounding very good:

1) The DAC must be plugged into the Pi directly, not into a powered USB hub. When the DAC is plugged into a hub, the audio is broken up and very distorted.

2) The mplayer.conf file must be updated with the setting

ao=alsa:device=hw=0.0

This prevents software resampling of the audio passing through mplayer.

3) MinimServer transcoding should be set to wav24

4) It's best to serve the music from a local instance of MinimServer running on the Pi. When streaming across the network, there are occasional audible minor glitches.
