Yes. I have such a setup.

Thanks Ratty.

Do you (or anyone) know if there are any limitations on the features offered by the Beam (Gen 2), that the Play:1s can't handle, owing to the age of the technology.

For example, I was wondering about eARC, but I'm not sure if that is just the connection between TV and the Beam (Gen 2) itself?

Cheers.

The Play:1s are just acting as "slaves" to the Beam, and are just playing the streams that are sent to them. You don't lose any functionality.

(I use Play:1s as surrounds to an Arc.)

Okay, thanks for the reply John much appreciated

Hi. 
will play ones as rears enhance Atmos content or is all that driven by the beam itself? 
is it worth adding rears? 

thanks. 

I have rears (Ikea Symfonisk) added to my Playbase and they made a big difference.  I would assume they’d do the same for the Beam.
