I have 2 Yamaha receivers with Bluetooth connected. On my RX-A3020, I am using the Yamaha Bluetooth module and on my RX-V575 I am using a Monoprice Bluetooth module. In both cases I connected them with the optical toslink output and sound is fine. However, I also have AirPlay on both and tend to use that instead because it does not have the 33 foot limit and it just sounds better.I have a Yamaha AV receiver that has the option to connect a Bluetooth dock. Has anyone used such as a dock to play music streaming services through their receiver? How is the music quality?
