High Res files are not yet available through ITunes, however I heard they are thinking about it. To load high res files you must use a CD and import it, selecting a high res option. I highly suggest in your import settings you select Apple LossLess with error correction. This option provides you with high res and corrects minor errors on the disk. This option does not take as much space as importing straigh WAV files, but it is a bit for bit copy, how it works I'm not sure but it sounds great. Enjoy.
