Spent a couple hours with Roon and I'm impressed. I cruised around my collection more or less like I would with real vinyl records. That's a pretty giant leap forward for me. Being able to seamlessly go between my files and Tidal's is great. I really like what they're doing with metadata. The suggestions, the radio feature, all cool. And who knew I had six performances of Leonard 'hallelujah!' I'm not in love with the UI. It feels like an of the shelf WordPress theme to me. But it's getting the job done.
There are some technical issues for me. I don't think it will run on my current VortexBox. So, the plan at the moment is to run RoonServer on my file server and keep the data store and the other servers on the music server. If I can work that out, Roon gets my $120 a year.
