If you are using it in a medium or small room, this does the job very well. The quality of this a/v receiver upgrades all the functions of a 4K HDR TV. We are enjoying using this item.

A really great buy that works really well to produce a substantial output especially if you download the iControlAV5 app from pioneer.

This has just the range of features I need and a very good balance between excellent performance and a realistic price point. Very satisfied thus far.

Replaced an Onkyo device which had gradually stopped working over several years. Same company but this seems to be a step up technology-wise. Also the slim design makes everything less cluttered - don’t actually need 7.1 nor multi-room so seems perfect.

This unit replaced a Sony in our 2017 Newmar Motorcoach. Sound is excellent and far superior. The auto setup made things easy. Beware, No pass thru for HDMI when the unit is OFF, so the HDMI switches are not being used, just the audio. Sub signal out to the powered sub is also excellent.

I bought this because my everyday hi-fi system has vintage and new components, and I needed a receiver with both HDMI and RCA connectivity. While this works just fine, be aware that it does not have RCA analog in/out capabilities for a tape deck.
