@alexb76 Many, many years ago I ripped my CD library to a Synology NAS using iTunes, installed LMS, and used it for whole house stereo via Squeezebox devices connected to NAD 7140 integrated amps and tower speakers in several rooms.
About 4 years ago, I ditched the Squeezebox devices for RIVA Wand powered speakers. I purchased a 2TB Innous Zenith MKII streamer and a Roon lifetime subscription. I hosted Roon core on the Zenith, and I ripped my CD library to FLAC on the Zenith I had two zones: RAAT in my basement listening room and rec room; and AirPlay to the RIVA Wand speakers on my first and second floors.
A couple of months ago I migrated Roon core and database to a new Mac mini. In my basement, I use Sense and Roon for my first and second floors. IMHO, the Sense SQ exceeds Roon by a wide margin. Both Roon and Sense use the Zenith’s "shared" music library. I stream Tidal, Qobuz, and JazzRadio.com. If you haven’t yet, give Sense a try if you can. I think you’ll be pleasantly surprised.
