You’ll probably get a number of responses, but no matter what anyone says here, pro or con, no matter how much research you do and no matter what people tell you, the only way to answer your question is by trying it for yourself. (They do a free trial.) The reason is that it probably doesn’t *do* anything that you can’t already do. I considered it for a few years and couldn’t figure out why I would need it. It turned out I don’t need it. But I’m doing a trial now and I love it. For me, it’s mostly a way of organizing my music, but Roon makes it brilliantly easy. Radio, stored files, Qobuz--all in sight and all ready to go. Give it a try and see for yourself; there’s no other way to know.
