hey, just saw this thread! honestly, I'd actually suggest a different approach if ur looking for the most bang for ur buck. Not to disagree with the other guys, but I think sticking strictly to the Sony ecosystem might make u overspend for features that aren't actually that game-changing in my experience.

1. Samsung HW-Q990C 11.1.4ch Soundbar with Wireless Dolby Atmos: If u can catch a sale, it’s basically the Atmos king. It includes rears and a sub, so the 'punch' is way better than a single bar.
2. Sony HT-A5000 5.1.2 Channel Dolby Atmos Soundbar: It integrates well, but make sure to budget for the Sony SA-SW3 200W Wireless Subwoofer. Without it, I'm worried it might feel a bit flat for movie nights.

Basically, prioritizing a dedicated sub over software features like the center sync might be better. idk but good luck! 👍

Seconding the recommendation above. Mixing brands often causes eARC handshake errors cuz CEC protocols arent always standard. In my experience, this can literally glitch your TV's HDMI board. Sticking with Sony ensures the voltage and signaling match, which is way safer for your gear long-term. You can usually snag the Sony HT-A5000 5.1.2ch Dolby Atmos Soundbar for around $799.

TL;DR: Stay Sony for hardware safety and reliability.

gl!

In my experience, you should definitely stick with the Sony ecosystem. I've messed with mixed setups before and eARC handshaking can be a total nightmare, honestly. Plus, if you want that Acoustic Center Sync to actually function, Sony bars are the way to go. basically, you can't go wrong with a higher-end bar from the same brand to keep things seamless. just make sure to check the dimensions... gl!

Yep, this is the way

Yep, this is the way

Basically, before u commit to Sony, u gotta think about how the audio is actually balanced. Acoustic Center Sync is a cool idea, but ur basically asking tiny TV speakers to keep up with a powerful soundbar. I’ve found that sometimes this makes the dialogue sound a bit 'thin' because the TV drivers don't have the same depth as the bar.

Respectfully, I'd consider another option. I know the first reply mentioned the Sony ecosystem, but I’ve found that modern eARC is actually super reliable now, so you aren't really stuck! If ur looking for that 'punch' you mentioned, the Sonos Arc Premium Smart Soundbar is honestly incredible. I was worried about it not being Sony, but it works GREAT with my Bravia and the Atmos is just... WOW. Plus, if u want a full setup, the Samsung HW-Q930C 9.1.4ch Soundbar usually includes a sub and rears for around ur price range. Sony makes u buy those separately and it gets SO expensive. I’m really happy with my setup and didn't miss the Sony features at all. good luck!!

Totally agree with Analiz on the handshake issues. CEC protocols are supposed to be universal but every brand tweaks them, which leads to those annoying glitches where the bar doesnt turn on with the TV. Since you have an A80L, you should really look at the Sony Bravia Theater Bar 8 11-speaker Soundbar. Its the successor to the A5000 and usually sits right around $850. Technically speaking, it uses 11 speakers instead of 9 and the 360 Spatial Sound Mapping is much more refined than previous generations. If you go this route, you get that Acoustic Center Sync you wanted, which actually works better on the newer Theater series because they optimized the latency between the TVs actuators and the bars drivers. If you eventually find you need more low-end punch for movies, adding a Sony SA-SW3 200W Wireless Subwoofer is a simple plug-and-play situation later on. Sticking with the same brand for eARC is just less of a headache long-term, ngl.
