Re: "The sound was better"
My main room has a Sonos Connect outputting to my NAD digital amp and very nice speakers I got off a Jehovahs Witness selling up to go and be a missionary in Sierra Leone (hope he survived the hurricane - he was quite chatty).
Its not like Sonos don't make stuff you can use, with optical I/o, with proper digitally designed audio equipment. I chose quite carefully. Not a small investment for a over a grands worth of audio kit on my day rate.
And the other two bits of Sonos kit which I already owned do their job just fine. Horses for courses.
