Question about Yamaha Wxad-10

Unfortunately, the "MusicCast thing" can only do stereo and is intended to connect conventional speakers and old amplifiers to the MusikCast system. I'd rather have everything new, sorry!

I have this Musiccast thing on a Yamaha RX-A2020, network-compatible receiver without Musiccast, and it works perfectly. You just have two apps to control it, but this way you can, for example, run Deezer on all the boxes connected to the receiver and control the whole thing via smartphone in the same WLAN.
