The Theater Trio was supposed to offer Theater Quad like stereo separation without its main flaw - lack of center channel. However, the resulting product was quite underwhelming. Pros: - Extremely wide soundstage. - Very good for Dolby Atmos / DTS:X movies - Very accurate room calibration with its included USB-C calibration mic - Center channel offers extremely clear dialogue once you turn off "movie theater acoustics" - Easy to setup. Every speaker was found almost immediately and I didn't notice any dropout issues. Cons: - Tremble was genuinely too much for me. It hurts. - If you enable movie theater acoustics, dialogue clarity suffers tremendously. - If you disable movie theater acoustics, the system could be quite silent for some Dolby Atmos or DTS:X movies. I literally had to turn the volume up to like 70 or 80 for the same level of volume the Trio system produces for a stereo contents. - The center speaker is ported but the bass level is pathetic. There is genuinely no bass or even mid to low range. Even with the sub 9 which is a seriously impressive sub at its price, the overall sound from the Trio feels empty (lack of mid to low end) and shouty (too much tremble) at the same time. This isn't obvious in movies but is extremely obvious when you listen to stereo music. - (?) No Acoustic Center Sync. I understand Sony might feel like the Trio's dedicated center can beat any TV, which is valid, but the Bar 9 / 8 also came with a dedicated center speaker, and enabling Acoustic Center Sync on a Sony OLED TV can improve dialogue clarity. Not sure why they removed a feature that many people use. Bugs: - Even a Sony TV with the latest firmware from 6/23/2026 often has CEC issues with this sound system. Both Trio and the TV can be connected and controlled separately from the Bravia Connect app, but they can't be controlled together because the TV fails to setup the sound system. This can only be solved by unplugging and replugging the HDMI eARC cable. I don't think at the current state of firmware and tuning, you should be purchasing this product. Sony seriously fumbled the ball here that made a more advanced system sound worse than its own soundbars, let alone the Theater Quad.

Hi Kimukatsu,
Thanks for the feedback. We really appreciate you taking the time to share such a detailed review. We're so sorry the HT-A8 fell short of your expectations.
To help smooth out the sound, we'd recommend using the equalizer in the BRAVIA Connect app to lower the treble and boost the midrange for a warmer, fuller profile on music.
For the HDMI glitches, a quick power reset by unplugging both the TV and sound system from the wall for two minutes usually fixes those connection drops.
If these adjustments don't solve the issue, please reach out to our support team directly so we can help you find a better solution: https://us.esupport.sony.com/support/s/support-contact?language=en_US&category=ht
Thanks for considering Sony. We value your input.
Warm regards,
Estefany
