Summary: I bought this receiver despite reading in the reviews that it had issues relating to the HDMI output because it had all of the features I need and was way less expensive than the alternatives. I figured that Onkyo had probably resolved the issues by the time I was purchasing the unit, after all it was January 2013 and some of the reviewers said not to pay attention to bad reviews before August 2012. Should have known better. The problems started almost immediately.
Summary: I've always prefered Onkyo and Yamaha when it comes to receivers, I decided Onkyo this time. Probably would have been pretty awesome if the thing had come fully assembled. In their defense, I bought refurbed, but I didn't think they could miss unconnected circuitry.
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.
Smart Receiver, great sound; but bring a friend that owns a Onkyo

Summary: I was replacing a 12 year old Sony surround receiver with this. As an engineer, making all the connections was easy for me, but then it was time to call in a friend.. The steps to link the ports together was confusing. I have used software products since TRS-80 days but the design on this one is awful. Even my friend that owns one, tho an earlier model, was confused on the setup. After 2 hours of try this and do that we got it working right.
** Updated: HDMI problem persists despite new firmware **
6 March 2013
Summary: UPDATED: This started out as a 5* review on discovery that I did not need to update the firmware, my unit came with the 400 version installed. But things went downhill since then - now I wish I could assign zero stars, not one. The well known HDMI problem did not magically go away with the new firmware. Yes, there are many satisfied reviewers, and I agree with them based on the feature / price ratio.
HDMI handshake delay, even after firmware update, but remedied....

Summary: Just got the 515 the other day with the TP-LINK TL-WN722N Wireless N150 High Gain USB Adapter. Followed all the tips about updating the firmware before all else. Set up standby mode with both pass-thru HDMI and network enabled. Connected all components, including Tivo, and even programmed the Tivo remote to turn on both the TV and Receiver with the same power button click.
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.
