Okay, I purchased a Denon 1803 in Summer 2003. When purchasing it, the sales person told me it was 90 watts per channel x6. I go to the Denon web site and look at the Denon 1804 (newer model) and it says the same thing (90 watts x6). But the thing is, in every review I see of the Denon 1803, they say the reciver is only rated at 80 watts per channel. So which power rating is correct ? 80 watts or 90 watts ?
