hello I'm about to purchase a SONOS AMP - I'm using it to connect my B&W speakers, subwoofer and turntable to my Sonos system. i'll be using it with both Airplay 2 and the Sonos App.
My question is - Which surround speakers should I buy? Sonos play:1 or Sonos one? I believe the former will work as a surround group using Airplay for music? what about Spotify Connect?
documentation is slightly spotty here.
