Hi @Elkiehound.

Welcome, thank you for reaching out to Sonos Community, We appreciate your time and effort in posting your concern here in our community.

Yes Sonos Arc has a rich sound quality compare to the Sonos playbar.

I suggest also to go to Sonos website to see how the arc perform in realy life.

Here are also the difference between the two.

Sonos Playbar

If you need help with any other information, please be sure to let us know.

I find a definite improvement, due to the width of the Arc. It ‘seems’ crisper, but that may be confirmation bias, and I’m unwilling to set them both up with a switch to do a real A/B blind test. 

The other nice things are the Arc has ARC/eARC compatibility versus the optical connection of the PLAYBAR, in addition to AirPlay 2 capability. 

Yea, I would probably go with a HDFury and sn HDMI switch to get the Atmos in the future. 

I did. My Vizio TV is incapable of passing Dolby Digital Plus out its ARC port. 

However, there’s currently very little Atmos content in my life. It will increase over time, I suspect.
