I visited the local Hifi imporium last night to discus my similar requirements. Newly decorated room; need to improve TV sound without clutter of additional speakers etc. I wanted ability to play music but my wife said this was secondary and was not going to happen unless it was discrete (proper Hifi is in another room supporting another TV so I/we can go in there to listen to music).
I’d looked at a few Hifi options but the speaker and clutter issue makes it a non starter. I’d also looked at a few soundbars in the past week and dismissed the cheaper ones as little better than the TV speakers; and the more expensive ones I liked the sound of (Yamaha) tended to be too bulky to sit in front of our TV. I also wanted it to be good with music and ideally be able to stream music without the TV on (without using an apple TV or the like). Music was where the ones I tried struggled… but much of that could have been the showroom but when it sounds tinny or the bass is disjointed as it can be from a subwoofer I’m not interested.
At the suggestion of the staff I sat down and was treated to the Sonos PlayBar. At £599 it was more than I wanted to pay but it was a very impressive piece of kit sonically and functionally (and not ugly like many of the soundbars).
TV must have an optical output and you need a tablet/smart-phone and ethernet port (or wireless bridge) etc but the world of music is at your fingertips.
I bought it and (shock-horror) my wife likes it :D
