No. While I don’t know what’s going on at Devialet, as an outsider here, I’d wager a guess that not a lot is happening in regards to AIR. I don’t know anything though, so be sure to take that as my opinion/guess.
We don’t know what’s going on within the AIR driver completely, but it’s pretty clear that the AIR protocol is not always lossless:
Maybe they are prefer the “fixed output” mode where the data is lossy? I’m not sure why they prefer AIR.
