I tried a little experiment this morning, I tried making REW measurements with Roon RAAT and then with Roon integrated AIR.
Not much in it from a pure measurement point of view, see below.
Although personally I would not dismiss the comments from those who hear a difference. I know from my own past experiences, such as when adding the Mutec MC3+USB, that you can get cleaner more accurate sounding bass, which subjectively may initially sound like "less" bass, but longer term listening reveals itself simply as better bass.
There are many reports that claim that low jitter results in subjectively cleaner bass. Maybe there is something like this going on between the RAAT and AIR protocols?
Of course, considering that the Devialet is buffering and responsible for the audio clock with both the AIR and RAAT protocols, it is difficult to think of a technical explanation for this, they should sound identical.
Another one for the "bits are bits" debate.
