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). If it kept working I might have rated it higher, but after a couple years the HDMI board went out.
No Sound After Extended Standby Mode as Reciever Ages (39 months in my case)

Summary: Onkyo has a great sounding product when it works, but it indeed has some reliability issues. I am a EE so it isn't like I am a novice with electrical engineering issues as I actually work in test engineering. The product when it was new would power up quickly because it uses a a massive toroidal coil.
Summary: Purchased this unit in 2010 November, so it is 3 years that I own it. Besides of having a complex setup to tune it to its user's habits, it produced a beautiful sound, but then suddenly speakers went dead. No sound coming out of speakers whatsoever. Looked up on forums - this is a common problem on Onkyo receivers, yet Onkyo does not want to recognize the problem.
Summary: This Onkyo very expensive receiver is an absolutely unreliable piece of crap. As a practical matter, given the role this unit plays in my home theatre, the lousy customer service of Onkyo, and the best-case estimate of how long it will take to get this thing fixed (the first time),I will have to junk this and pay for another (from someone other than Onkyo). I will, however, have a new hobby: trashing Onkyo with a vengeance. Amazon should demand better of Onkyo.
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. If it were not for the problems I am having, I would give it 6 stars. I won't go as far as saying don't buy one, because if you get one that works, you will love it.
Summary: I use this as my surround sound system and as my music amp. I purchased this Onkyo as my all in one system, with a mind on high amps and later upgrades to the rest of my surround sound. Currently I am only set up with the 5.1 surround sound, using Bose 901's as my front speakers, Bose 601's as my rear speakers, a Bose center channel speaker, and a Yamaha sub woofer. Most surround sound DVD's are still in the 5.1 catagory.
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 for service. When I got the 55 pound beast there the women there pointed to racks of Onkyo receivers with the same problem .
Summary: This receiver worked great out of the box for a couple months then channels cut out sound clicks out for no reason and lost connectivity to the network. I took it in for repairs twice the first time they replaced the HDMI BOARD as the said its a common problem. This did not fix anything. They could find the problem. I am supposed to be able to stream 3D movies through it but that doesn't work either. There is only 1 repair place in Edmonton but they can't fix it.
