If I had a bunch of local files to play and my internet went out frequently, I would purchase a lifetime subscription to Audirvana Origin and be happy. Use Roon with internet and Audirvana when my internet is down. How simple is that?
The problem is when you run Roon with a dedicated NUC… in that case you are simply NOT free to switch to different player… and this 2.0 put a SERIOUS limit at user freedom to use his own music, payed and stored locally, when and how he likes… that is bad, no excuse
I have three copies of my music, one copy on my Synology NAS and use MinimServer, its a great UPnP Audio Server. I stream to my Naim streamer/DAC or straight to Hegel Amp, Done! I still have Qobuz through phone. I done rely on these guys - I did fine without them, Roon is just a pretty interface!!!
I also have a backup for no internet.
My Roon Server is on a Mac mini.
All my ripped cds and purchased downloads are in ALAC format, and I have an Apple Music library with the same files.
If/when internet is out, I just open Apple Music and my library is just right there.
