Im not a fan of itunes myself, but what bitrate does itunes format it to. If it's quality you are after then u need uncompressed sound and thats what itunes or mp3 does, does it not? So for uncompressed sound, try ripping a cd onto ur hard drive with wmp 10 but 1st check the settings. In wmp 10 click tools, click Rip Music tab, then down below you will see a slider bar, move that to the right then click apply, then rip away.
Best of luck !!
