I'm currently running an old iPhone as my digital audio source but have been thinking about swapping in an old Mac Pro tower I have sitting around instead so I can control it remotely and access a bunch of old files I have stored on its hard drives. I've been looking at some music players but was wondering whether anyone here had some they liked. I've heard Roon is good, but $120 on top of the Apple Music and Spotify subscriptions I already have seems pretty steep.
