Last night I watched a movie through iTunes (Apple TV) and got some weird results. I had to turn the volume way up (+1-2 dBs), which I normally never do and it still wasn't that loud. I'm thinking it has something to do with either Audyssey attenuating the heck out of my set up or poor streaming quality through iTunes, or both. At low to moderate volumes, vocals were breaking up too. I've heard vocals break up on occasion, but I've always written off as it being the result of a bad "source".

My front stage consists of:
L/C/R: Towers and Horizon all with NrT
Powered by: Denon 4311

Anyone else run into a similar situation? Just a hypothesis, but is it possible that Audyssey is applying too much EQ (taming the sound) which is requiring me to turn up the volume past Denon's comfortable limit? I'll rerun Audyssey and experiment with different sources.
