Very nice! I already love Mlem so I can’t wait to try out the next generation!

This. I just returned to Roon after a years hiatus when I saw that this feature (streaming outside the home) had been added. And the just added “MUSE” to the streaming as well. The sales pitch for MUSE is: MUSE is the new name for Roon’s sound engine and audio processing suite. And now MUSE has landed in ARC – with bold styling and sound quality never before seen or heard in a mobile music app!
