Summary: This receiver was great for a year and a half. It progressively started having trouble with the HDMI SWITCHING until one day it would not switch at all and the hemisphere connections were unavailable. That was an essential feature for me since the Tv was a ways from my components.
Summary: I read a great review of this receiver in Sound&Vision magazine. I bought it. It sounded great for a couple of months, then BLAM. It started making horrible noises when in certain listening modes that were loud and nearly blew all my speakers. I found out later by the pathetic repair service that some video resistor burned out. And no wonder - this receiver gets hot enough to be intolerable to touch. Yes it was ventilated, and my speakers were standard large Infinitys.
Summary: As per the previous reviewer, I also had a bad Audyssey mic, and thus couldn't use the auto room setup. Onkyo customer service insisted that it was because I had my system bi-amped and wouldn't work under that setting. I doubted it, and undid the bi-amp, and of course same problem. My brother came over w/ his Denon mic, and surprise, it worked. But that said, under manual mode, sound was good, remote decent and it did not run hot.
