I value it for multiroom, metadata, many endpoint support and remote access. I paid the fixed cost as it is very important to me for all my ripped CDs and music downloads stored on my Synology NAS. You can also connect Qobuz and Tidal streaming.
Tidal just announced on Monday, it’s terminating its integration with Plex. The cofounder of Plex implied it was Tidal’s decision, and employees have flat out said it was Tidals decision. It’s an odd decision considering Tidal could use all the subscribers it can get. Plex monthly is half the cost of Roon, and lifetime is 1/8 the cost, so hopefully the premium price for Roon will ensure Tidal integration stays.
