From your posting, I wonder if this is because of the AVC (Automatic Volume Control) setting? I had been thinking it was simply a bug in the firmware which caused the momentary "blast".

It is... I have set mine very low because I've experienced the same blast. If you set the AVC all the way to the left you'll find the blast effect goes away. Actually, it still is a firmware issue in the sense that whomever programmed the darn thing should have made it use a running average of speed rather than the instantaneous speed it appears to be using. Apprently it gets a spike in the readings sometimes and it responds and blows your ears off.
