Best streaming solution

[mdconnelly]

yes I understand, the question is: if I use the iMac, I have to install the software Devialet AIR or is integrated in the Roon Server software?
Again, if both options are correct, there are differences in term of SQ?
Thank you.

If you're using Roon to stream to Devialet via AIR, definitely use Roon AIR instead of Devialet AIR.   At least, in my opionion, it is far more of a solid solution (although Devialet did improve Devialet AIR in the last iteration).   

I've used both (via a Win 10 PC) and I don't hear a difference (other than, of course, Devialet AIR occasionally glitching).

If you do use Roon AIR, you definitely want to turn off Devialet AIR or, better yet, just uninstall it.

Sorry have to ask ......im back home after a long period and start to play with my roon set up again
In Roon you can choose  either Roon ETH or Roon AIR....whats the different since both need a Ethernet cable to communicate with the Devialet ? (if dev air module is shuttet down)

 do i miss something here,i have shuttet down devialet air module

In my Roon setup (Settings -> Audio), Roon sees my Devialet under "Networked" as 'My Devialet - ETH'.     That is the networked connection using Roon AIR.  If you have other connections to your Devialet, you may have other "Networked" choices (e.g. USB), but I'm not sure where in Roon that you're seeing a 'Roon AIR' choice.
