I too need a better system from cataloging classical albums. I use a Melco N100 NAS and 2 Cambridge Audio CXN2 streamers in my house. The CA streaming app is an improvement over other apps but I still wind up with multiple listings for the same composer, with multidisc box sets split between the various tabs, etc. I lasted looked at Roon many years ago and didn’t like it, I had to reload it every day of my free trial and the last time I thought the MacAir I was using as a controller was going to blow up.
Should I try again? And would I need a new piece of hardware? And does it run Apple Music? The Roon site only mentions Tidal and Qobuz
