To keep the thread on track - I love my K10s! Actually, I chose ALAC for lossless ripping via iTunes. I use Audirvana on both home and office Macs. I sync with my iPhone and set to auto compress to AAC since I don't have enough storage space for lossless. I don't really listen to my music via iPhone much. For portable I manually copy all of my lossless files to my AK240 and then use a utility to convert iTunes playlists to M3U files and copy them over to the AK240 root directory. I do the same manual sync for my office laptop since I no longer use Double Twist. Thanks for the info, I should just get off iTunes and convert everything to FLAC.
