best soundbar to go with era 300s

The Arc Ultra is the top of the Sonos soundbar line, I really like mine for mixed TV and music.

For just music the Era-300s are the best option for Atmos, for stereo the Fives.

I did add a Sub to one of my Pairs of 300s and it is a nice improvement if your music has a lot of low end content.

To get “best sound for… music”, i would say don’t get a soundbar. Stick with Era 300’s if you want Atmos, or a pair of Fives. Whichever you go for, also add a Sub. Otherwise, Sonos’ best soundbar is the Arc Ultra.
