WAV vs. AIFF

I was quite impressed with the Exemplar cdserver at both the RMAF and CES. It uses Windows XP so I had no choice but to use WAV with maximum avoidance of error correction. It goes to my Exemplar dac by way of a Lynx AES/EBU output. Thus far this is the best reproduction of digital I have heard. I have four Macs including the one that I use as a remote desktop to run the server. I have heard Macs used driving a dac through the USB2 port, but it is not really close. I do wish it were possible to get Mac processors for use in the server but think it is impossible.

How do file sizes differ WAV vs AIFF vs Apple Lossless vs FLAC?

Does iPod play FLAC? iTunes?
(I don't see where iTunes will rip cds into FLAC)

tbg, why maximum avoidance of error correction with WAV?

Too get the best read???

So in your experience not using error correction when ripping CDs to a HD or server results in a better read? My reason for asking is that I'm about to rip some CDs to my MAC. I was planning on using AIFF with error correction. Your post has me rethinking that or perhaps trying it both ways.
