Hello,
I own a Playbase, two One speakers, and a Gen 3 Sub in my living room. It's a system I'm very happy with, and the only thing I'm missing is compatibility with Atmos, and maybe later on with the Sonos Ace. Recently, I bought a 4K Panasonic player, and I'm really excited to try out movies with an Atmos audio track.

I've read in many places that the Playbase sound is better than the Beam 2, with more spatial depth and better bass. I’m not sure if this would be balanced out with my current setup of two rear One speakers and the Sub 3.
Also, I'm not sure how much of a difference it would make to watch a movie with my current setup in Dolby 5.1 compared to watching it with the Beam 2 and the rest of the components in Dolby Atmos.

Right now, I have all four HDMI ports on my TV occupied, so I’d probably have to connect it with the optical adapter. I don’t mind losing HDMI CEC functionality and similar features, but I’m unsure if this would mean a lower sound quality when playing Atmos content.

I would appreciate your help and feedback.
Thank you!
