Yamaha RX-V685BL review
The RX-V685 supports just about any format you can think of (MP3 / WMA / MPEG-4 AAC). It also supports 4K Ultra HD, HDR (high dynamic range) video including Dolby Vision and Hybrid Log-Gamma, and of course Dolby Atmos and DTS:X. Music is presented with the same character – clean and clear, detailed and defined (especially using the Pure Direct mode) – although it does lack that last ounce of color and texture you may find in a dedicated two-channel amplifier in the same price range. Comparing Yamaha RX-V685BL vs Pioneer VSX-933 I found out that they are both 7.2-channeled. The RMS is 90/8 and 80/8 W/Ohm respectively. 
Pioneer VSX-933 review
The Pioneer VSX-933 AV receiver supports 5.2.2 surround sound in Dolby Atmos and DTS:X formats. In addition, on board the device there are two speaker outputs in a separate zone and a pre-out for the second zone. Like the LX103 model that was presented last month, the new product is ready to work with 4K / 60Hz video, as well as with HDR10, Dolby Vision and HLG, but differs in the absence of connectors for automation. To connect the sources on the rear panel of the Pioneer VSX-933 posted six HDMI-inputs. There is an upscaling function to UHD.
