One of mine got bricked, likely by the 14.6 update*. I'm looking at moving on to another, maybe Sonus. I really haven't started looking. Recommendations for quality sound? AirPlay 2 support?
My wife prefers using Bluetooth or wired to a Harmon Kardon Studio (4?) from her iPhone. It does sound great.
(*Any suggestions on a fix are welcome. I'm not going to pay Apple $279. for a replacement. The hard reset doesn't work. It was removed from Home app and removed as an Apple iCloud device. The other three have been updated to 15.3.)
