Wired or Wireless (with RAAT) ?

[Jean-Marie]

For now my Expert 250 Pro has always been used as "ROON READY". 


That must be automatically through RAAT. Is that true?

It should be the case, but the best way to be sure is to click on the little star to show the signal path. 
If you look at this example: https://community.roonlabs.com/t/deviale...ion/154912, it shows Roon RAAT as the first example and Devialet Air as the second one. 

I hope it helps.
