I watched 'Air America' Blu Ray last night & played with Dynamic EQ a bit. Dynamic Volume is always OFF for me.

I set the RLO at 0 with MV at -10 Db where I normally listen to movies. I toggled DEQ On & Off & found that with it OFF, the sound was generally 'thinner'. I preferred it ON.

Some find that with DEQ ON, bass becomes bloated and/or muddy. Similarly the surrounds are too loud in the mix. This didn't happen to my system; however, I believe that those that find that their bass response becomes too much, they probably are running their subs hot already...
