robdob – Sonos is usually rock solid. On mine, a unit is wired in to the router (optional) and then it creates SonosNet – the more you add, the stronger it gets. No drop outs in a year, just works flawlessly.
I also have a Connect – it’s a streamer only, wired digitally into my amp and speakers and it sounds superb. Not cheap, but sound cannot be faulted. It can be played through an external DAC and Amp if required.
wobbliscott – expensive solution, but if you like YouTube and are expanding, I have a Playbar and my TV has a Chromecast. I cast YouTube to the TV and can then group the playbar with other players and send Youtube music round the house. Dumped 7 boxes (5 speakers, amp, network switch) and put in the playbar – far cleaner living room, loads more flexible to move and toddler safe!
