Samsung - QS730D

The best option for the Samsung TV specifically would be either the Q600C or the Q730D. They both use Q-Symphony (uses soundbar and tv speakers for fuller sound), and they can both be controlled through one remote/app (Samsung Smart things).

Grab a samsung 3.1.2 there around 300$ open box Canadian usa prob like 199$ I forget the model

I’ve had the sennheiser ambeo, Bose smart ultra, and the Samsung q800, in that order. First two were returned for connectivity issues with my newish Samsung tv. The q800 has been great (the ambeo probably had the best surround but only if it connected). Q symphony is amazing. With the first two bars, you could clearly tell the sound was coming from below the TV… q symphony fixes that completely. And the subwoofer is amazing.

Don't buy a soundbar just because it's the same brand as the TV, I tried Samsung's Q-symphony and it's ass. I also switched to a Sony TV while keeping the Samsung soundbar.

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)

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.

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!

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.

I picked up a 3 month old Samsung QS730D with rears 9500s which makes it a 5.1.4 for $190 shipped.

Hw-qs730d (used, search internet) + 9500 rears (used) from bestbuy. Definitely will fit under your budget and even allow you to add stands for the rears.

Qs730d (used/renewed) or 800d (used/renewed). I wouldn't pair this level of a TV with 600c even though it's a decent soundbar and even if it were new.

I was in the same exact position. I ordered a Samsung TV and HW-Q600C soundbar "for fun" in the beginning of this month. Liked the concept so much but returned both to get better models.  What I can say based on my countless hours of research: as of now, the best "budget" but decent quality system is hw-q600c especially if you can get some used version on Amazon or eBay.  The next best system for money is a used / renewed HW-QS730D. This is basically an improved version of the q600c with a better subwoofer, Wi-Fi and FLAC/ALAC support, as well as AirPlay 2 and others. I've realized how important wifi is for loseless streaming. You can't just do it on BT, have to use HDMI.  If you want to know what I ended up with: I've found an HW-Q800D for $370 on eBay from a reputable seller. It's used, but turned out to be like new. I guess enthusiasts here would say it's a steal. I am impressed with the quality of this tech.  Good luck! Added: I see you're concerned about design. Look up hw-s800b and related. Used of course if you want to save up a noticeable amount! 

The Q-Anything is nice. I freaking love, e'm. Just snatched up HW-QS730d(3ch atmos) and SWA-9500's(rear ch atmos). I'll say this for sure, it gets LOUD. So, a 5.1.4 gives great ATMOS.

Get the Sonos system. Samsung is terrible at support. Further you can buy the Sonos components from Costco. At least most of them. Return policy is quite generous as you probably know. Don’t be tempted by the Samsung pricing. It’s just not as good or reliable as the Sonos systems. He’ll even the JBL soundbar systems have better sound than the Q series.
