Air 3.0.4 Officially Released

[Rama]

I would like to clarify my point. I did not mean to imply that the USB cards are different. However, I feel the implementation of the USB input is different with the 220 pro. I bought the Audioquest diamond USB cable but never used the USB input that much with my D200 as i always found the sound to be lackluster. But when I plugged the same cable into the 220pro it was an instant realization that something was different. I used the same source my Melco. I cant elaborate with audiophile terms because my vocabulary is limited when it comes to that. But we all know the moment when the magic happens during changing of equipment or accessories, you instantly realize wow this change is for the better. I agree with Confused that its because the Expert Pro is a better amplifier, with better power filtration. But Devialet must have put some thought into improving the USB chain inside the Expert Pro, I dont believe it is just by chance. As for the exact technical details only Devialet can elaborate.
