FLAC or AIFF? your choice for importing to Itunes.

iTunes doesn't do flac. You can download flac, but need pure music or similar to convert /playback.

Stick with AIFF. Storage is cheap these days.

FLAC. It is a more universal solution and will future-proof your library better...

If you are planning to use USB, then FLAC has the worst imact on SQ of the losless formats. AIFF is not as good as .wav, but a lot better than FLAC.

I will not argue about this. Yes, FLAC is bit-perfect when data compares are done, but it compromises SQ when played back real-time. There have been a number of studies including the one in TAS that support this.

It depends what you're going to do with it. If you send it wireless or to network Bridge/DAC then it doesn't matter (as long as playback program recognizes format). In case of Itunes+Airport Express, for instance, it is even better to keep it ALAC compressed since Itunes uses this format in transmission to Airport Express. Using AIFF would require additional processing.
