i usually plug the y cable for my iPhone and have the hifi (standard audio in us). i found the audio quality better with usb key and actually quite good (don't et playlists from iTunes but folders) with less noise, less saturation, and sound more clear.. am surprised to hear such a difference between jack and usb...although audio quality is pretty good already with y cable.
am considering transferring iTunes library to usb key, do you know if there is an easy way to transfer playlists to an usb ?? iTunes saves the mp3 in folder by artists apparently.
