Trying to leave iTunes - music management alternative?

[ethelthefrog]

I am finding my system for managing and playing music too complicated. I have my library on an external drive connected to a Mac mini so that I can manage the music using iTunes - playlists, ratings etc. But I play the music on Roon. The Mac is connected to a microRendu then to an Arcam iRDAC/A38 Amp and out to KEF LS50s.  

 

It seems to me that thus far Roon is not the best place to be doing the management. I’d like a solution like a NAS or Rock or something else that connects directly to my DAC/Amp but still lets me work with my files easily (like iTunes). Any ideas?
