I have my iTunes set to downconvert audio to 128k for my iPhone and iPad to save space. However I'd like to sync Apple Lossless files to the devices as lossless, and only downconvert lossy files that are more than 128k. Possible? Reason I ask is this - I bought a Pioneer AirPlay dock yesterday and would like to test the sound quality of Apple Lossless on a decent speaker like the Pioneer. I believe AirPlay supports streaming Apple Lossless. I have obtained one album in Apple Lossless format, however I think I'm right in saying to get it onto my iDevice I'd have to untick the "cover higher nitrate songs to 128k", which would force iTunes to re-sync my entire 30GB music library just so I can test 1 album?
