I currently own the PLAY:5 (1st generation) and recently bought a pair of KEF LSX which I have upgraded the FW to support Airplay 2.
My plan is to buy an additional Sonos One and group it with the PLAY:5 to bring Airplay 2 to both speakers. Then in step 2, group the KEF LSX and both Sonos speakers via Airplay 2. Objective being to play music on KEF LSX, PLAY:5 and Sonos One at the same time.
Has anyone tried something similar and can share whether this would indeed work?
If so, can you use the voice control while remaining grouped over the brands to change songs and receive the Alexa output?
