Hi Gene,
A while back, right before this new Audyssey Dynamic Volume update became available, an AVP owner from AVS posted that he was having some issues with the volume just spiking all of a sudden when he would engage Dynamic EQ.
Well none of us (so far) have experienced exactly what he's going through, so we figured that it was just due to something going screwy with his AVP. Here's a video clip he took of his AVP audio doing this.

Two days ago I experienced something similar but the way mine happened was totally different. With his AVP, various inputs so this when Dynamic EQ is set to on. On mine I experienced a loud volume spike (went from -30db to 0db in a matter of seconds) when I was listening to streamed music. I was listening to a playlist using .WAV files, all 2 channel tracks with the exception of one that was DTS 5.1 encoded (Steely Dan-Hey Nineteen).
Audyssey was on on the Net/USB input (which I didn't realize until the volume spike occurred), and all was well listening to the 2 channel tracks (in Direct mode). But once the DTS 5.1 track started to play, Audyssey kicked in and almost immediately the volume spiked!
Everything else is just fine and all sources on various inputs are just fine. But then again, all of the other inputs (except CD), are always in some surround mode, where as Net/USB is always in 2 channel Direct and Pure Direct mode. So what I experienced could be some weird thing with Audyssey not handling the change from 2 channel to multichannel very well.
If this is a bug from the recent update, maybe Denon can see about a fix for it. If you could, can you let Jeff know about this issue? For ones who have this happen and do not happen to have the remote in hand, it could possibly damage some speakers.
Just though this issue was important enough to let you know about.
Thanks Gene.
