I was toying around with the idea of building a system using my PC as the pre/pro. Run cables from my PC to an amp which powers the speakers. Does anybody know if this would work? I'm not sure if the soundcards outputs would work like pre-outs.

They tell you to hook it to a receiver, but a computer has volume controls and processing, so all I need is an amp right? Could somebody please correct me if I am wrong (with technical evidance from a reliable source).
