The caveat to all of the following is that these days I mostly listen to podcasts. But if I'm just listening to music, I have only 3 listening scenarios, all using Apple Music through my subscription:

CAR: iPhone connected to a wireless carplay adapter (my car has carplay but only wired). This is annoying because of the delay in all controls. But it sounds...fine.

HEADPHONES: either through Airpods Pro or the Airpods Max I just got. Sounds good.

HOME: all through Sonos speakers.

That covers everything for me. The empeg was ahead of everything else at the time. But these days I've basically just fallen into "what's the most convenient?" And a listening library that follows me everywhere is best for me. I don't really like the Apple Music app though.
