Thank you for the question. I do know some Yamaha receivers do support AirPlay. If this is the case for your receiver, reposition of the router is not required as the receiver should be able to connect to your AirPort Extreme. However, if your receiver does not support AirPlay, purchasing an AirPort Express might be the best option. Below, I have included an article that goes over AirPlay. See the section that covers "AirPlay requirements and capabilities". Also, refer to your receiver manufacture's Web site for details on if it is compatible with AirPlay.
