I bought recently Samsung HW-Q990D, generally better rated than similarly priced Sonos. Had a bit of mental resistance with the Samsung+audio pair, I am more a Sennheiser type of person.

Sound is fine, not hifi just a notch below, but good hifi surround is a 10k thingie. They cost 500-800 in Europe, much less than Sonos surround+sub solutions. No issues with connectivity, connect via eArc with TV without issues and starts with it, bluetooth with both Samsung and Apple OK too. Have some extra features when paired with Samsung TVs. One detail I love - extra bass control on remote, so I can move it down easily during late night watching (low frequencies travel better through walls).

I like them a lot and run Spotify from phone on them all the time.
