Been using Jriver for some time now. Not so intuitive at the start as one hopes but once learned you can do anything, make endless tweaks and configurations.
New Layouts, multiple endpoints/rooms is it strong points. Searching for tracks is so easy to.
The fact I just tried roon and it failed in so many ways. sound and connection issues. Couldn't connect to my moon mind 180 as I found out needs an £800 upgrade to be roon ready
Happy to pay 20-30£ every few years for an jriver upgrade. Works well for me.
