Very happy with this receiver so far.I prefer the large physical buttons on the front as opposed to knobs for input selection. Easy for my wife or kids or others to select the input. It is easy to change the digital label on the inputs (ie, Streaming Box button says ROKU on the led display).

Mine at least has a defect. Sometimes when listing to music i'll get static popping on the right side. I've switched the plugs and the sound moves to the left speakers so I know it's not the speakers or the wiring. Contacted them and they want me to drop it off at a shop 2 hours away.

I have had this A/V receiver for almost 2 months. I love it! Paired with the Onkyo 7.1 speakers this baby rocks. The sound is great with music and movies!

Great product. Not tech savvy so I had brief difficulty setting it up. Not plug and play.

Great receiver! Bought this Onkyo to replace a Denon that did not have a pre-amp and found the set up to be easy for my minimal skills. Love the features and ability to fill our big high ceiling room with sound!

I bought this a month ago to replace my 10 year old Onkyo receiver which had developed a few faults.Easy to install and set up , reasonably simple to use and excellent quality of sound and performance.

My previous Onkyo TX - NR906 died of the HDMI capacitor failure issue after 8 years so can’t complain. I was thinking either for a straight Onkyo replacement or the new Sony which has won rave reviews.Tommy in New Southgate gave me excellent advice based on my home system and set up.

Had it for 6 weeks now and very happy with the purchase. I was originally looking at a Sony or Marantz but once compared the Onkyo was a better purchase. The sales advisor was very informative with the advice, not pushy or trying to upsell a more expensive AVR.

Bought this amplifier a couple of months ago, along with an Oppo UDP UHD player and Dali Zensor 7 floorstanders. So what do I think, well sounds great. Since I'm only running a 5.1 system the Dolby Atmos is a bit wasted on me.
