Roon is more than just a music player, it is a catalog of your digital library, it offers the convenience of 2 streaming platforms, and it’s an interface that is agreeable with most people.
Is it worth the price? I think it depends on what you value most, personally for me it is the best solution to navigate and play my personal music collection. I have Qobuz linked to it, yet use it sparingly as I will use Qobuz when I am not at home. The major downside of Roon is access when you are away from the computer running the Roon Core.
An alternative is to use Plex, you can link it up to Tidal and access your music library outside of your home.
Hope this helps.
