I just recieved my ep500 and it's way more than I expected. It out weighted my pdr12 by 60lbs! I have Paradigm monitor 11's for fronts and 7's for rears. I found that setting both front and rears to large made everything blend better. I have the ep500 set at half and bypass. The volume is about 8 o'clock. My room is 16x20x8. When I set my speakers to small the ep500 is way too noticeable. It seems like most people like the small setting. Could someone explain if I'm hearing right?
