Joe,
some interesting thoughts. I'm curious about your preference for THX Ultra2 Cinema, as the manual states that THX Ultra2 was designed for 7.1 setups (see page 79's table for TruHD, and page 84 for THX ultra2 cinema description):

I assume you are expanding the trueHD 5.1 native source to 7.1 since you have a 7.1 setup, correct?
I switched between THX Cinema(engages THX loudness and Re-EQ) and regular (Audyssey DynamicEQ engaged), and found that under normal Audyssey dynamicEQ, the surround dynamics were better for my room, since I'm using 5.1 at the moment.
