Simple, easy to use, great sound, and great new features. I particularly like the new bluetooth connectivity, and the flexibility of both RCA and HDMI connections (as well as 1 USB connection).

This receiver has everything that I need to play music, connect my tv , it has Bluetooth and a usb port up front. It's plenty loud and sounds very good.

I purchased this to replace a 20 year old Onkyo receiver. After two months I am still amazed. The Bluetooth connection makes it easy to listen to music, and the sound is distributed to all the speakers. The automatic speaker set up is fantastic and so easy.

Purchased to replace an aging 12 year old Onkyo home theater receiver. Everything connected just fine and sound quality is amazing! The remote is great. There are a couple of things I expected from Onkyo at this price point that they just don't deliver on.

This is the perfect unit for my second system in the bedroom! Has enough features i.e bluethooth so I can stream music from my tablet.And as usual great quality from Onkyo!!

It takes a little while to customize the audio settings to fit your style. The process is well worth it. I started out with letting the stereo calibrate itself to the room. Then I went in and fine tuned the settings. Surround sound is rich, distinctive sounds are now clear.

Great receiver for a great price. Set it up in about 10 minutes and my speakers sound wonderful.

Great combination of performance and easy set up. I did not need or want the network features as I have all that in my ROKU tv and other devices...

Be warned. Bought this March 19, 2017 at a Best Buy. By April 24th the game input started acting up. Whenever hdr was needed the input would fail. Worked fine tI'll that time. I did some research and this is a common problem with other buyers. Going to exchange it later today.
