Onkyo TX-NR686 review
The power of this unit is 7.2 x 165 W (6 Ohms). The AccuEQ auto-tuning system takes into account the location and type of speakers mounted on the ceiling using the AccuReflex function. The Onkyo TX-NR686 has seven inputs and two HDMI outputs. With the exception of the front panel entrance, they all meet the most modern requirements for terminals of this type. There is support for HDCP2.2, 4: 4: 4 60 Hz, BT.2020, HDR10, HLG and Dolby Vision. 
Denon AVR-X1500H review
The 7.2-channel AV receiver has the power of 80W per channel (8 Ohms). Control the Denon AVR-X1500H using the Smart TV remote control using the HDMI CEC function. Simply set “HDMI Control” and “Smart Menu” in the receiver's menu to ON and you can control the AVR-X1500H using the TV remote control. The Smart Menu screen provides quick access to source settings and surround modes, as well as the AVR settings menu. Discover superb high definition audio quality. The AVR-X1500H plays all modern audio file formats, including ALAC, FLAC and WAV (up to 24 bit / 192 kHz), as well as DSD tracks of 2.8 MHz and 5.6 MHz. 
Onkyo TX-NR686 pros & cons
Pros
- The power upgrade was great, and it should fill a small to mid-sized room, it should be more than enough for the average user, and it sounds really great
- The area 2 output on the NR686 is amplified and works great. I can operate it from the external area and play my Spotify independently, from my cell, while the kids watch cartoons in the living room
Cons
- Video (4K) is really bad. Keeps fading to black and than back, sometimes it goes to static
Denon AVR-X1500H pros & cons
Pros
- Sound is crystal clear and has plenty of power
- Unit does not run hot at all, even in a theater cabinet
- Build quality is great, it's a heavy unit
Cons
- The on-screen interface is super ugly. It looks like some sort of retro 90s DOS text interface with huge block letters and no graphics
