Ethernet in : AIR vs. Core Infinity for SQ

[baddog]

So when you ask, which has better sound quality,

"Ethernet with AIR or Ethernet with Core Infinity?"

Is the question ethernet via AIR on an Expert Pro versus ethernet via AIR on an Expert Pro upgraded to the new Core Infinity board?

I have used an ethernet connection to my D440 Pro for quite a while. I have used Roon with its support for the AIR protocol for quite some time too. I can state that the sound quality is certainly as good and maybe even a little better, after the Expert Pro was upgraded with the Core Infinity board.
