I find that if using iTunes on a PC, AIR sounds best with both the PC soundcard and AIR GUI settings at 16/44.1. (assuming you are listening to 16/44.1 material) If the PC soundcard settings are at 24/192 there is a noticable drop in sound quality, I'm guessing this is because the PC's own software is performing upsampling duties.
