Agreed, if money isn't a concern get Steve to hook you up with one of his options and skip all the experimenting. If value is a concern there are lots of cheaper alternatives to keep you busy.
Best Digital Input from PC to DAC
I'm currently using a Kimber USB cable from my PC to my DAC to play FLAC files ripped from my cd collection to a hard drive. Although the results are quite good I'm interested in other Goners experience with USB or alternate input choices using a lap top computer for manipulating music streams. I've found that FUBAR and the free ASIO drivers render the best results in play back.
