I am sure that someone will chime in on low level info but AIFF is basically uncompressed digital audio from the CD source and I'd the default format on Mac computers. In theory they should be identical quality because you are playing the actual digital file. The issue would hong on the equipment in the chain
I am sure that good quality DACs will yield a superior sound; however if you are on a mac and have a newer model you can use the built-in digital out and use a toslink connection and feed of to your audio system. If you have an escient fireball or an apple tv or airport express you can likewise stream or feed your pre amp or receiver.
So if you can feed things digitally try that and compare to an existing higher end system. Though I have NAD and Denon cd players (yes not super high end) I prefer keeping all my music in apple lossless and serving it from my home network server via my apple TVs toslink connection to my Anthem preamp. I love the sound and the flexibility. If I use a cd once every 8 months that is a lot.
