I got a Blusound player to demo from my rep yesterday. Initial impressions are fantastic. I really like the APP, almost like the original blue sonos app. simple, straight forward and easy to use. Integrates in just fine with C4.

The sound quality difference is staggering. Night in day ABing between sonos (set to the highest quality) I made sure I was using CD quality and not Lossless on Tidal for a fair comparison. I have it for a week, will report back with what I find. The only problem is there is no Pandora which will be a deal breaker for most. I understand why they are not offering it but it seems a little silly considering it has Bluetooth and Tune IN. (horrible streaming quality)
