airport express questions

The airport express is equipped with a mini-jack that is a combo: analog and digital toslink. Monster sells a variety pack of cables to go with the unit, including a mini-to-full toslink cable, and a mini-to-RCA cable.
How can I be sure that I am streaming digital audio with airtunes? Is there a box in some dialogue window that I need to check? For analog audio, which I don't want, does the airport express have a crappy internal DAC, or would the laptop be wirelessly streaming analog from its own crappy internal DAC? Laptop is a 5 year old Sony Vaio, windows XP. Thanks.

Thanks guys - I was thinking about the MF V-DAC - which I don't think has good jitter reduction. I can always add a re-clocker later...I have a birthday coming up and I want to get into PC audio. DAC would be connected to an ancient Yami receiver, running B&W 685s and a HSU VTF-1 sub (connected via speaker terminals).
BUT I would need a toslink cable with a mini-plug on one end and a full size plug on the other. I found one on monoprice.com, thanks, these look good. Any idea where I can find a high end one? I think I saw "van Den Hul" or some such makes one?

Realremo - I think that Airport Express receives files in Apple Losless format. Keeping files stored in Apple Losless makes one conversion less.

the airport express will receive any type of file that you ship it. you can use itunes or airfoil for xm/sirius radio. if you want a better connection, get a glass toslink cable. big difference over a plastic toslink. i go from the airport express or apple tv into a jitter device using glass toslink, then use a coax digital cable into an external dac.

You can buy a great mini to full toslink cable, all glass fiber, from Van Den Hul- the Optocoupler II. Highly recommended. Or you can buy a convertor (full to mini) that works perfectly well and use that with a standard toslink. I do however recommend glass fiber- the difference is not subtle.

I believe that Kijanki is saying that airtunes protocol utilizes apple lossless as the file type from the pc to endpoint. So any file sent via airtunes is converted to lossless and then back- aiff, aac, mp3, etc.

That is how I understand it works as well.
