Best streaming setup with the new CI board

[AlexS]

I am wondering what people's experience is with the new CI board. I received my upgraded Expert Pro on Friday and here is my impression so far:

1. ..
   
2. Streaming from the Synology NAS directly to the Pro via UPnP and Audio Station works well. No need for a laptop in the loop. It can all be controlled via the DS Audio app on the iPhone. (Notice this was not quite the case with DOS 2.1.0. I had to upgrade to DOS 2.2.0 beta 12.) But how about sound quality? How can I control that the Pro is really receiving bit-perfect data at the correct frequency? How about the extra smoothness (processing ?) provided by Audirvana when the Mac is present in the loop?
   

With UPnP, the Renderer (that is, Devialet) receives the music file itself (e.g. .flac) which it then decodes and plays. The bit-perfect concept does not even apply here. In theory, you get most stability out of this protocol (since the data are sent to Devialet in the compressed format, and are decoded by the Device). SQ can''t be possibly worse than AIR (probably not better, either), as long as the audio decoder functions properly.
