Summary: I bought this based on the needs I had for the room I was putting it in and the reviews I had read about it. This unit was very easy to setup and start using. I have a Pioneer unit in the living room, but wanted something that was a step up in performance and have not been disappointed.
Summary: I had decided on a TX-NR515 months ago, when I began plotting my home theater redesign. And then I started reading reviews. It wasn't encouraging. It seemed like everywhere I turned I read complaints about not powering on, HDMI switching problems, no audio, and I think one person wrote in that flying monkeys shot out the top the first time he plugged it in (a firmware update should address the flying monkey problem, I'm told).
Summary: I was VERY VERY hesitant to buy this after reading all the problems people were having. However I needed a reciever and after a lot of research I ended up buying it. 2 months so far, works perfectly. The specs at the price are simply hard to compare to any other reciever as it has the most features for the lowest price of "reputable" brands.
Summary: I Just set this up yesterday along with the Onkyo Wireless adapter. I don't even have speakers yet (There on the truck i should get them monday). So i have been listening to it through my Wireless Headphones. (The wireless headphones were a little tricky to hook up the way i wanted them to be hooked up but i finally got it) So if you need help i would be happy to help answer any questions on hooking those up.
Incredible value with advanced features that actually work

Summary: I replaced my Harman Kardon AVR 2600 65W 7.1 channel Home Theater Receiver (Black) receiver, which was only a little over 2 years old, but had, apparently, suffered significantly from a couple of lightening strikes (HDMI ports, subwoofer, default sound level and zone 2 speakers all died). I like the Onkyo better. I will say, though, that the Harman Kardon did seem to have the warmer sound people say they are known for. Still, the Onkyo is an upgrade.
Summary: First - YES, I would recommend this product! I am lovin' this thing. I fell in love with Onkyo back in the early 90's when I was trained on them at Circuit City - I mean really trained, not that bulls*** training they give these guys today. You put anything up against an Onkyo and Onkyo will have it for lunch - well, almost anything. But if you're thinking (Yamaha - CRUNCH=Lunch, Sony-Chomp=Lunch, Denon-Yum=Lunch, Pioneer-Tasty=Lunch!
Best receiver "bang" for the buck? **Updated Sep 2013**

Summary: This review requires a preface. Let me start out by empathazing with you if you are searching desperately for a quality receiver. The reason you are probably reading the reviews is because you NEED to make sure your money is well spent--and you don't want to deal with returning and trying other models over and over. I am in your boat (rather, WAS in your boat).
Simply incredible product now that new firmware is out!

Summary: Okay, I know all about the issues with this and similar Onkyo models, you probably do too. However it seems that Onkyo has corrected the firmware problems for most users. I do not have the "clicking" upon sound mode change reported by Keely below, in fact my 515 does not change sound mode when changing channels or FF'ing. That may be an issue with that person's DVR. Even when my 515 does change from Dolby to 2 channel it does not click.
