Apple Lossless, AIFF or WAV for itunes?

I have noticed in my system that wav sounds better... even using dbpoweramp to convert flac to wav, the converted files sound better... Can't coment on AIFF as I use PC, but thought it was worth mentioning.

.wav has the best SQ, but AIFF maintains the tags and SQ hit is not too bad. Any format can be saved on the NAS.

Since you said "for iTunes" you won't use FLAC unless you use
a third party player software that works in tandem with iTunes since iTunes
does not directly support FLAC. my choice would be AIFF or ALAC
because of the metadata support and I personally do not hear a difference
between any of them.

I use AIFF. Haven't spend much time comparing the different formats because I find this sort of A/B testing tedious. AIFF seems to be a nice compromise between tagging ability and lack of compression. General consensus seems to be that WAV has the potential for best fidelity while FLAC/ALAC may not sound as good. Storage is so bloody cheap why bother with compression at all? I mean, this is a site dedicated to maximum fidelity, correct? What's a few hundred bucks extra for storage capacity in the context of a most of our systems?

WAV. I have a WAV album downloaded from Juno that sounds much better than a FLAC rip through my Naim DAC. In fact, I'm astounded how much better it sounds. Only if WAV was more readily available to buy.
