I like to rip my CDs to AIFF for Hi-Fi listening. However, I like to have more storage on my iPod. Can I keep one iTunes library with AIFF files and the other with Apple Lossless for iPod syncing? On the same computer. Since I can not hear the difference between AIFF & ALC on iPod, no need to on AIFF on it. However, I can hear the difference on my Hi-Fi system so I have to have AIFF there.
