Summary: This receiver is discontinued so I'm just noting my experience. The unit worked pretty well and had lots of features, my biggest dig is that it would not forward digital sources to the Zone outputs (many AVRs have this problem, check out Emotiva processors if you need this feature).
Summary: My 5008 lasted 20 months before having the same problems as everyone else. I had to send it in for repair. That was 3 months, 2 weeks ago. I still have an old Yamaha sitting where this 60 pound beast sat. The sound doesn't even come close to the Onkyo.
Summary: I ordered the Onkyo tx nr5008 for my new dream home theater. Within 3 months the receiver began cycling through all of the listening modes with no sound at all. I called customer support and after jumping through all the required hoops I was told that my new "FLAG SHIP" receiver would have to go in...
Summary: This unit worked well, as others have documented, for a year and a half. Last week it started to spontaneously switch function to the Cable/Sat input, regardless of what I selected. I unplugged it and let it sit for a few minutes, and it worked for a little while longer.
