I am wondering what the cleanest way to hook my PC up to my Sunfire Theater Grand II Pre-Amp. I understand you want to get the signal as least decoded as possable to the pre-amp. You want the pre-amp to do all the decoding considering it is better at it. I am just wondering the best way to do that. I am guessing when it is coming from my Sound Audagey sound card it is getting decoded some if not all then sent to my pre-amp. I have a Optical out on my motherboard but that to is tied into my sound card. To keep it short what is the cleanest and best way to send the signal so I am not loosing anything.
