Summary: This receiver sounded great for all of 2hours. I wanted so much to love it, but wasn't meant to be. Watched The Matrix and a little over 2 hours into it, flash, crackle, and plume of smoke. The unit did not feel warm. Ventilation was not an issue, because it was just sitting on the tile floor. Didn't want to put it into the cabinet until I was resonably sure I had a good version, knowing that this receiver has potential heat issue.
Summary: This receiver performed very well for a month, then I turned it on one evening and was greeted with sparks and smoke coming out of the top of the unit. I am getting a replacement unit ... we'll see!
Summary: The overheating problem with the SR805 is REAL. It fizzled, sparked and died during the Jacksonville-Pittsburgh playoff game Saturday night. What's worse... I called Onkyo and they said that I will have to take it to an authorized service center. I've only had the thing 10 days and they would not even consider swapping it out. That basically means my 10 day old receiver is now refurbished.
