well i consider myself a high end guy and i have 3000 songs in my i-tunes library send the signal via airport express using apple lossless compression the sound is very
very good on most songs is it perfect whose to say however
the reproduction is audiophile grade to me

Using Apple iTunes to Apple Airport Express with an Audience Conductor Cable connecting it to my SLI-80.

It Actually Sounds Great. It does miss the Magic of my XA777ES but sitting on the couch with the Laptop in my lap rolling through my 20,000 plus song collection in iTunes is pretty cool and easy!

I eventually plan to purchase an Electrocompaniet DAC to run the Airport Express into but just not in a hurry. It sounds decent all things considered.

I also use iTunes and two airport expresses (one for the living room, one in the bedroom) and run both through the digital ins of my Pre/Pro's, while my stiff is still compressed, it is a huge perk to have the entire audio library available to you...

Soon I will re-burn the 600+ CD's into my MAC as lossless or AIFF and stream it in native rate... Just ahven't gotten motivated enough to buy the HD and, more to the point, go through reburning my entire collection..
