I disagree regarding Sonos. As a Sonos user for many years, with several rooms of paired Sonos speakers , I find Sonos more and more limiting... The new app is NOT great. and if I want to send any audio to the speakers and I can't.. only the services they support in their app. this is why bluetooth is so great... So, if airplay 2 works as well as bluetooth with awesome audio quality, and no crappy dropouts like the current , it has the possibility of being a great solution as long as the speaker quality is great.
