I definitely don't crank them up that loud. The volumen level is usually at about 30 when watching a movie.

my receiver does have an impedance switch. it says to keep it at 8 for a mix of 6 and 8.

Just wondering if something like the Denon 3803, 3808 or 3810 would be good? I've seen some used/refurbished ones at a decent price that I could pick up. Wouldn't mind something that decodes DTS Master HD and Dolby TrueHD rather than having TMT do the decoding.
