overly familiar with many other manufacturers apps. However, I suffered greatly at the hands pf Pioneer's app when I owned the Pioneer N-50 network player.. It was beyond atrocious. Therefore I sought other alternatives, BubbleUpnp and 2Player (both of which I purchased after trialling) and a variety of others from the Playstore (Android user) provided a vastly improved, polished and user friendly experience.
The Yamaha MusicCast system is a joy to use, easy to set up, reliable and very easy on the eyes. I just wish I had other systems throughout the house to set up multiple zones. It seems to merge well with streaming services, I've only tried Spotify and also on occasion access Amazon Music as I'm a Prime member (for next day delievery mainly)
I'm sure there are many other MusicCast app users here that can offer better insight into how it compares to similar apps. But personally I couldn't imagine it being much better.
Edit and app unrelated. My one and only slight reservation concerning the Yamaha WXC50 is the volume knob on the front of the unit itself. I personally think they could have done a little better., too plastic to touch compared to the solid metallic feel. I saw an Australian online video review and the reviewer stated that Yamaha initially delayed the product launch there because they were unhappy about this themselves. Not sure if it was the same over here in the UK and what version of the volume knob we got... I believe BlackSabbath on here said the same after receiving his unit but in truth, you don't ever go near it. The build quality is very good, it doesn't feel like a half empty case as the picture above shows. It has a good overall quality feel and weight to it. I sound like a Yamaha fanboi now! ;-)
