Looking to jump into Sonos. Confused as to whether to just get the Beam, Beam + Sub, or Beam + two Play:1s? I can’t justify all of it at once and want to build the system over time. But if I could wring out a little more $$ what approach would you recommend? Use case is mostly TV:music:games about 50:30:20 in a small-ish family room/study 14x10. Thanks!
