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,

If i have all my music stored in Apple Lossless format and I'm streaming it directly from my iphone to my airport express and in to my Bryston DAC is it the same as streaming it from my laptop?

In other words, if the files are apple lossless on my iphone, are they streamed that way, or down converted somehow?
