AIFF vs Apple Lossless Ripping

Thanks, Al. Your explanation makes perfect sense (as usual). Perhaps even Solid State Drives can really sound better, as Steve N. suspected, for the same reason of electrical noise being converted to jitter.

I feel lucky with my setup where computer is separated from the rest of the system while music stored in ALAC is delivered wirelessly bit perfect to Airport Express also in ALAC (no decompression in computer) to finally reach jitter suppressing Benchmark DAC1. Computer clock/timing is completely separated since data is buffered and AE creates its own output clock. AE and DAC1 are plugged into filtered outputs of power conditioner (Furman Elite) while data is supplied by short glass Toslink.

I said, I feel lucky, since my main reason for AE was to keep computer near sofa (doubling as home computer) and not the electrical noise.

Ripping my CDs under AIFF is the best then?

   I have to rerip over 3000 CDs. Not looking forward to this!!!!

in a previous post, I was trying to critical listen to my ref system using my iPod with 128k, and was laughed at :). 

So using aiff would be much better?  I will start as soon as I get the time. 

Pecan I put the CDs in and when prompted, click "replace" or just delete the old album, and rip again??  What is recommended?  Thank you and I look VERY forward to your relies in this subject. 

Why not rip your CDs to ALAC which is Apple's version of FLAC?  You get much smaller file sizes, about 5% of original, no data is lost, and all of your devices seem to work well with ALAC.  I don't see where AIFF offers anything of value to you...

Please excuse my typo in the last post, the file sizes would be about 50% of original, NOT 5%...

I only have these options when I insert cd into my cpumpuers cloud drive (external)

aac -which everything I have is ripped to

aiff
apple lossless
mp3
wav encoder

for aiff , there's options. Sample rate, sample size, and channels I can choose from.     Best options???
