Summary: I did my research before replacing my old (failed) receiver, so I knew I could be faced with some trials getting the firmware working correctly on this unit...and sure enough, doing the first upgrade was pretty much a pain. But I found the right kind of USB memory stick, finally figured out how to place the correct firmware on it, and was able to successfully upgrade to a firmware package that works pretty well.
Summary: I am running a TiVo, a Roku and a DVD player through this receiver into a Sony 46-inch TV. No problems at all. Everything sounds good. I read some reviews and was worried about having to do a firmware update, but no such problems. It's hard-wired to a modem, and Pandora radio sounds good. Haven't even tried Spotify yet. It's a little bulky but not too bad, and as others have said, the display/graphics call to mind the pong video games of about 1980. But so far, so good.
Summary: It works pretty well. Pretty good audio quality with my Polk speakers. Its the absolute low end when it comes to built-in networking stuff from Onkyo, but I knew that going into it. All those apps have a text-only display, no graphical menus at all. Not that its really that bad, as normally I'll navigate the internet radio features from an app on my phone instead of actually looking at the TV.
Summary: This is a very reasonably priced high capability receiver. Price is excellent for what you get. Ease of use is good once set up. Sound quality is fine. I did not encounter some of the firmware upgrade horror stories in other reviews. Worked fine out of the box and upgrades have installed without difficulty or incident. I use the basics with sound and video from DVD player via HDMI, ROKU via HDMI, TIVO (sound only) via optical, and computer (sound only) via RCA inputs.
Summary: I've had my Onkyo plugged in and working since January 2013 and it works as expected. The setup was pretty simple, except for the on screen menu. There is no setup GUI, and it's not exactly intuitive, but it's no like reading Chinese. After suffering a glare from my wfe, I read the manual and then it was fairly easy and striaght forward. I like the network connectivity and the net radio, since I have it in my basement.
Summary: I saw this recommended from a well-respected electronics review site and bought it sight unseen. Easier than expected setup and it was programmable with my cable remote. It's a pretty plain design, but you'll never go wrong having extra HDMI outputs to have the flexibility you need for all your components. Glad I bought it.
Summary: I don't know much about quality audio equipment, but after reading a review on cnet about this receiver I had to check out whether Amazon had it. Not only did they have it, but it was on sale! I purchased this product immediately. Unfortunately, the item arrived broken. I emailed Amazon and they had a new one to me two days later. This one works great. I have the system set up with surround sound and the quality is amazing.
Summary: I am not an audiophile. I got this to replace an old analog Onkyo receiver I had. We use it mostly for channeling the sound output from our TV through it. The channels in the old one were going bad and static filled until the receiver warmed up. The new receiver wasn't any more difficult to set up that the old receiver had been.
Summary: had issues with HDMI cables, this thing just didn't like some of them for whatever reason, thought I was having issue with video passthough for a while but different cables fixed my issue.
Pros: good price, works well for me
Cons: very poor user interface, especially for the internet options. android phone app can't find my receiver, app has no option for entering IP address manually, dunno why, would prolly work if it did.
