Hi Chris,

If you don't have any stored music (CDs records etc.) and mainly stream, then Tidal is the way to go. As Carl has said, Tidal will work with both Roon and Sooloos to connect into a Meridian system (818). With Tidal, you get your first month of membership free so you can play around with it on your iMac and see what you think. I particularly like the playlists that they create as it gets me wandering off into new (and old) music that I wouldn't have heard otherwise. To be honest, I don't listen to much classical music so I haven't really explored this in Tidal, however, a quick search has revealed 123 albums of Mozart so hopefully you'll find something on there!

I'm not sure how much experience you have of either Sooloos or Roon? Useability wise, they are both pretty simple. I am currently setting up my new QNAP with Sooloos and Roon to gain a greater insight into the differences between them when controlling Tidal. Currently, I use Roon to control Tidal on my mac smile

I don't know much about the Crestron side of things, but I'm sure that there are people/dealers on here who do smile Are you hoping to have control of Tidal on the Crestron touchscreens or simply use them for basic controls of the Meridian system?

I hope that this is of help,

Peter
