I am taking delivery of a 3801 next week. It needs to drive a HT room (16'x21'x8.5')with a full 7 speaker system and sub. The F/C/L speakers are Dynaudio Audience 122s (6ohm,86db). The surrounds and back surrounds are PSB in-ceiling M6.1R (8ohm,92db). The sub is a PSB subsonic 7. I never understand what people mean when they say small, medium and large rooms. I think I have a medium room. Does anybody have an opinion as to whether this system will come close to the "movie theater" sound I'm looking for (aka reference)? Thanks.
