Ok, now that I've searched, I've found quite a bit on this subject. I am looking for a way to attach my optical XMPCR to my M10000 without using a PCI optical soundcard. I positively can't fit it into where my MB is fitted. Is there such a device that allows optical input from the pcr into my board? I hve no more inputs into my amp and the analog connection for the PCR sounds like crap.
