I am considering a new receiver for my HT and music but everyone I talk to says the "Watts per Channel" spec quoted by the manufacturer is a bogus number. My older Pioneer VSX-D508 states 100WPC. The power consumption number in the back of the manual reads 280W. Do I divide this number by the number of channels or what? For example: If I am watching a DVD in 5.1, do I divide the 280 watts by five? By six? What about 2 channel music? Divide by two? I apologize if this is a basic question but I'd like to know what to expect from a receiver. Is it true that I should "buy by the weight(actual pounds) of the receiver???
