computer to preamp?

You can use the audio outs on the back of the PC where you normally connect the speakers. If you still want to connect speakers, you can get a Y cable. Another way would be to get a Hi-End sound card from Audigy or someone else and use it's audio outs. And of course the best way would be to use the digital outs into a Hi-End processor then into your 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
