So. 15 years ago I bought Bose stuff. It was a speaker system, hard-wired, served me well, through an old (25 year old) Pioneer amp, TV sound, CD player through the same source. All good. Amp failed. What's next, then? Did my research, and ended up with a choice between Bose and Sonos. In the end, the fact that the Bose speakers were working well, sounded good, I stuck with that company. Added big wall speakers too, rewired, moved mini speakers, connected the new Bose amp via ethernet, bought satellite speakers for the rest of the house as suggested. Wrong choice. I have had to buy two x Sonos Onto listen to the radio. Now my Bose system has disappeared from the WIFI system. Shocking. Wish I'd bought Sonos 5, etc. Left with some expensive bits of black plastic with Bose written on it. Very angry with Bose but delighted with my Sonos speakers.
