Get a Samsung QS-730D from BB. Or, find the used/Amazon Renewed Q-800 (my personal setup is Q-800D with SWA-9500S rear speakers)
Yes, but I'd wager that he wants a full body sound stage. Pick up an open box Q-600C/F or QS-730D, then test it out. You'll be very surprised. I personally have a Samsung Q-800D (5.1.2) with Samsung SWA-9500S rear speakers (2.0.2) combined with the TV speakers (Q-Symphony) for a total of a 7/9.2.4 channel surround sound system. Along with the 77" S90D streaming through an Apple TV 4K ethernet model, it's truly an immersive experience! You won't be disappointed if you decide to get one. Even go to Best Buy and listen to a demo model on display!
Get a Q600F and turn the sub down to -1 or -2. Great little system. Or, find a QS-730D. Its the same 3.1.2 system but with a better audio processor than the 600 series.
Try to get a QS730D if you can. Theres not much difference between the D and F series. If anything the D series is better.
I picked up a 3 month old Samsung QS730D with rears 9500s which makes it a 5.1.4 for $190 shipped.
I currently have a qs730d with 9500s rears its good but im just looking for something new for the new tv
If you can do without the Dolby Atmos, just get yourself a somewhat entry level Samsung, [Samsung HW-B750](https://www.amazon.com/SAMSUNG-HW-B750D-ZA-Soundbar-Expansion/dp/B0CTKTRYX7?th=1) This really does punch above its weight, I think I have a 730 C? That is more than enough to change how you hear TV content. I did have a 9 series Samsung and that was immersive, huge sound. Samsung do make some of the best soundbars around, 7 series is what I would be looking at and fits your budget.
The q symphony is hard to notice if I am being honest. Not because it isnt good, it seems decent, but I had a 5.1 Logitech PC system before. The THX was nice but 11 speakers of Atmos is so amazing that adding 4 is like putting chocolate fudge on a chocolate bar after just eating vanilla wafers for years. Its richer and you cant say no, but the chocolate bar would have already been more than enough at this point. And yeah, I pushed to 30 for a bit and it was a lot in most cases. Went to 50 for fun and started getting worried I may blow a speaker out haha.
A soundbar is always an improvement, even if your room was 3 square meters. That is to say, Samsung soundbars are very good, but don't count on Q Symphony. It has an echo on Dolby Atmos content and almost all content is Dolby Atmos nowadays. You'll probably just not use the TV speakers at all. You definitely have no use for a flagship soundbar with rear speakers, like the Q990F in such a room, or any bedroom, for that matter. But depending on whether you want and have space a dedicated subwoofer or not, yiu can either get one of those Samsung soundbars with a dedicated sub, or an HW-S60D, which doesn't have one and will lack punchy bass, but will still provide a much better sound than the TV. It's also super small, so it will fit on any width of a cabinet. All soundbars are designed to be able to sit on the TV's pedestal stand, so don't worry about that either. P.S. Soon a standalone Samsung soundbar with an internal subwoofer, kind of Sonos-style, will be released. But it will probably be wider than your TV and cost as much as the Q990H flagship, so you might not be interested in that.
