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.

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.

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 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.

Very well built unit and working perfectly.

29 December 2017

Great sounding receiver that plays nice with HTPC at 4k60, easily handling codec switches, etc. Note that there is NO power-on HDMI link. Inexplicably this receiver omits an age-old feature that detects power on your TV.

29 November 2017

Works fine, but sound quality and flexibility not as good as more expensive units- good value if your needs are basic.

23 November 2017

this receiver is so awesome I love it surround sound is Epix I give a five star
