I know there are 1000's of variables in any home theater equation, but I'll throw this out there and maybe someone can help.
The "beginner" setup
Pioneer Elite VSX-92TXH
RF-82 Fronts, bi-amped.
10x20 Room
The only input into my reciever is a Comcast HD box. (Is the compressed signal to blame)
How loud should I be able to turn up the reciever so that it's too loud to be in that room?
