Poor quality switches
Main power switch didn’t work and since I didn’t get a chance to install when I ordered it, I can’t return it! Once again Amazon gets my money.

Exceeded expectations
Style: Receiver
We have 2 tower speakers, 4 ceiling speakers, a center speaker, and two subwoofers and, wow, the sound is amazing. The key is the microphone which is used to set the relative volume and delay time for each speaker. Comes with media app which allows access to my audio files on my network storage device and lots of streaming apps. Kudos to Yamaha.
