If you look inside of all three receivers, the 809 looks like it definitely has heftier capacitors, a larger power supply and a beefier amp section. So as far as power is concerned, I think the 809 has more. Will you hear it? Maybe not. I don't notice a difference.
Sorry for the double post, phone is a b*tch with multi-quotes.
While it is true that the 1222 and 1522 are identical soundwise, I, personally, find Class D amps to be sonically superior to Class A/B. The reason why I upgraded from the 1222 to the 1522 was that two extra channels, OSD, 12V trigger, and THX certification was well worth the extra $100.00. I was not embarrased at all to have the Onkyo 809. Before the Pioneer, it was the best sounding receiver I had ever owned, partly because of Audessey. Personally, I don't like MCACC - it dulls the sound in my room, so I prefer it disabled. To me, if there were one reason not to get a 1222/1522, it would be MCACC.
