Something I have been wondering. Many have strongly recommended that I get the Denon 1802 (80w/ch) rather than the 1602 (70w/ch) and for good reason I am sure. Even though the price difference is only $60 all this does is give me 10W more per channel and Binding posts for channel B speakers. Is it worth the difference or a waste of money? I am not questioning that more power isn't better but once one has enough to go well beyond what their ears can take what else does the power get you (more reliability, Lower distortion, lower background noise???). What I thought: The power headspace above normal (lets say reference level) is to handle the HT/Music sounds and peak effects that can take one up to I think I read 121 db. Now for systems that have a powered subwoofer the receiver amplifier is only driving the speakers above the crossover (80hz to 100hz) which are not the frequencies that require the power I thought. I thought the power is demanded by the Low frequencies (redirected bass +LFE) that are now handled by the subwoofer (all speakers set to small). There probably is no short answer to this but I am interested in why so much power ( I can see paying for more features). I dont want to be penny wise and pound foolish but I don't understand the quest for more power.
