ASIO-Support in iTunes
For the best sound quality in windows you need ASIO-Support.
Why ASIO isn't included in iTunes?

None of us know, the best we can do is suggest you leave feedback -> Apple - iTunes - Feedback
Maybe you can search the web for a iTunes plug-in, or check the manufacturers support forums for somekind of fix.
