I mean picked up a q990c a while back and it’s been just amazing. I was on the ‘don’t wanna compromise and get a soundbar’ camp before, but it’s pretty spectacular if you have a medium size space.

I mean if music is your priority, and you’re an audiophile nothing beats a pair of bookshelves from a reputable brand. If your focus is surround sound and movies or gaming, soundbars are great. Don’t get me wrong, soundbars are okay for music but you can get much better sound from bookshelves for the same price.

But those same bookshelves won’t be as good for movies or gaming. So it’s a question for you on what you want, and what compromises you’re willing to make. Soundbars are compact and fit in most rooms no problem without worry about wiring up surround speakers and stuff.

Ya, however if you google Xbox Series X Dolby Atmos delay issue, there are tons of complaint.

Currently my setup is Xbox Series X, LG CX and Samsung Soundbar Q950T:

1) Connecting Xbox direct to LG CX and eArc from TV to Q950T will have the audio delay [this setup will have 4k120 HDR/Dolby Vision & VRR]

2) If direct connect Xbox to Q950T, the Dolby Atmos delay will eliminated but then it also disable 4K120hz & VRR.

Previously Dolby vision also cannot work but after firmware update, it has now.
Last time Samsung even advertise this is the first HDMI2.1 enabled model in their page which later took down :\

False advertise, meh..

I assume you haven't bought the device, right ?

In my case, it is the xbox audio issue which specifically - Dolby Atmos as well as my Samsung Q950T model

Samsung Q950T has limitation on the HDMI port that will not passthrough 4k120 and VRR
Samsung Q990D has remove this limitation and both HDMI 2.1 ports inputs supporting 4K120Hz and VRR, pass through HDR10+ and Dolby Vision HDR formats.

Xbox Series S/X on the other hand has Dolby Atmos delay if connect into TV (4k120 capable and eArc) and then eArc to Samsung Q950T or most of the audio receiver (can find issue in reddit or microsoft forum)
Note: if using DTS in Xbox, there is no delay. ONLY Dolby Atmos right now.
Note 2: Due to limitation of Q950T, if I don't wan DA lag, then i will need to sacrifice 4k120 and VRR once i plug XBOX into Soundbar and eArc back to TV.

Conclusion:
For PS5 you have no worry, there is zero lag if you use Dolby Atmos.
You can :
1) PS5 > TV < soundbar
2) PS5 > Soundbar > TV

Ouch

So now waiting a new one come back ?
