I have also seen this! Although I will admit that I just assumed it was my MP3's, however now I'm not so sure - I will have to listen in on a pair of headphones now :) Actually, I was playing the thing quite loud the other day and it 'screeched', I actually thought a very large rock had hit the car!! Then my girlfriend said it was the empeg.

I also get seemingly random reboots during the middle of a song. Entirely unreproducable on a song-by-song basis :(. I just figured it was a dodgy ver 1.0 bug or something.

Maybe there's more to this than at first meets the eye. I shall listen to a track that I know exhibited the problem to see if it's clean.
