Nice!
I use dbpoweramp to flac lossless format. Music server is Plex and library resides on a usb drive connected to PC running Plex server. I often use airplay to stream to various hifi devices at cd quality from iPhone mainly. Plexamp is my main app on iPhone for streaming via AirPlay. Also use other music streaming apps that stream at cd res like radio paradise.
Picard is free and also useful for auto tagging when needed to supplement tagging in dbpoweramp. Also dbpoweramp provides the manual tag editor that is useful in rare cases when auto tagging fails.
Also digitize my vinyl collection slowly over time and add to my music library. Use a Rega mini phono to Audacity digital mastering software on PC for that.
I may try Roon at some point if I add a high res streaming service like quobuz but with thousands of ripped albums and growing and Spotify to explore when needed (decent sound but not cd res) I have more than enough to listen to for a long time.
I recently replaced separates with a Cambridge Evo 150 all-in-1. Review coming here soon.
