Apple Airplay Sound Quality


What is the potential for sound quality via Airplay? Is this essential WiFi? Or Bluetooth? What technology is being used and what are the limitations? I've reviewed all the material I can find and don't see that information (in my own non-technical language, anyway).
Thanks,

Single hangup with the AE is HUGE jitter. Some DACs, my 840c among them, simply do not like this amount of jitter, and have audible problems.
I thought the stereophile test measured large amounts of jitter?

I know my 840c simply doesn't like the optical input while the analogue output of the AE is only OK. But, in this case convenience trumps ultimate quality.
My lossless files transmitted in this fashion easily best the MP-3 / 320 or so stuff off the small dish / sirius feed.
