That looks like a neat unit. You can also get a fully fledged network surround receiver for the same price. They will have built in apps for Spotify, Pandora, and maybe Tidal (not sure) and airplay support. I'm honestly not a fan of using your phone as the source because it ties up the device, you have to worry about battery life, and there are still occasional problems with music streams stopping when the device locks etc. And Airplay can be pretty nice but it is very hard on your wifi network since the signal bounces around a lot. For what it's worth I have had much better experiences with Airplay enabled receivers than with Airplay via Airport express. I never was able to get the Airport express to reliably stream without dropouts.
