computer to preamp?

Best/Easiest Approach would be to use and Apple Aiport Express and Stream your Tunes Wirelessly into the Airport Express from iTunes.

I would suggest you use the Airport Express in conjunction with a Bel Canto or Benchmark DAC then hook that to your pre-amp. Itunes is free, the Airport Express is $129.00 and both DAC's can be found here on Audiogon.

Of course you will need a digital cable and decent pair of interconnects.

Good Luck

hi i am not very computer literate, if i se the airport express, does it have to be connected to the router/modem?
on my laptop, it has a 54g wirelles card, how does it know that airport express is there?

The Airport Express can be used two different ways. To answer your question, yes your laptop with 802.11g will recognize the aiport. If you have an existing wireless network the Airport can will simply join your existing network. If you do not have a wireless network, the Airport Express can be configured to operate on its own and your laptop will recognize it as well.

The Airport can be used alone and has a DAC in it which is not terrible but defintely, not high end. It is really a GREAT product.

can you get a digital output on an airport express? I have one but the only output it seems to have is a low-fi minijack

Below is a long link to apple.com its for Airport Express Stereo Connection Kit. One of the connectors is optical which can be used for connection to a DAC with optical imput.
