I went the same way (got something that I could play my TV through) and am now enjoying better sound from all my sources. Removing the soundbar and it's stand not only got me better sound but better looks, to boot. A lot less clutter.
I'm also enjoying FM on a level that I never thought possible.The sound is so clear, full and enjoyable that I turn it on first thing in the morning and leave it on until I choose something else. That can sometimes take hours and it's simply lovely to have it in the background again, after way too many years of going without it (the reason being it never sounded this good with my precious set ups).
No need for room acoustics here. To me, it's a waste of time and kind of self defeating. Talk about chasing the dragon. I listen in the near field (7.4' from the plane of my speakers) and the sidewalls are far enough away to not worry about 1st reflection points. I've even had a sound engineer and a high end audio dealer over and they both said the room is great the way it is and not to waste my money.
For me, the process has always been one of synergy (I don't like that word but it's apt) and after being in this hobby for some time now I can (mostly) ferret out the BS and pretty much hit on what I'm after. It takes a while. Sometimes a long while, but I get there. The thing is to be patient. Let things settle. Experiment a bit if needed but don't go down that rabbit hole and buy one thing after another. This "last piece" of mine (my new integrated) took 8 years of waiting (with one misstep) to finally get it right. Ignore the naysayers who advocate their special way and please discount their claims. They just like to bloviate.
All the best,
Nonoise
