You could try a third party player, such as Audirvana, Amarra or PureMusic. They tend to improve sound quality, especially over USB. I use my Macbook Pro via USB to my D200 and use Audirvana (currently testing v2.0). I think Audirvana is a significant step up from iTunes if you use USB. When using AIR I mostly just use iTunes with the Bitperfect switch in AIR on. It's almost on par with Audirvana.
