Good thread-
My only question is why does my Avia Guide to Home Theater DVD suggest setting THX reference levels at 85db? They actually knock setting it at 75db since this can cause softness in the center and surround channels during movie playback. They also state that 85db is the movie industry standard reference setting for theaters.

I have set mine at 80db to split the difference and I did notice an improvment with surround / center track on movies.

Comments?
