I had that problem with the music streamer pro and other dacs. Best I could tell it was from electrostatic discharge. I have a full size pc and when I put the dac and amp on the case so they were touching, no more problems with static. The loud burst is because the USB signal is getting lost and the clock screwed up. It took me a long time before I learned that, after trying separate powered hubs that didn't work for me.
I'm using MS HD with speakers, does these loud bust damage the speakers in any way?
I use to have these busts quite often, but after about 300 hours burn-in, they have almost completely disappeared, the sound is also getting clearer.
