I have been looking at the Alpine PXA-H701 with a sound card that will allows digital out (probably the Audigy PCMCIA). I want to keep things digital as much as possible until just before it goes into the amp.
Looking at the manual for the Alpine unit it shows three sets of digital inputs. Creative lists the Audigy digital out as 'SPDIF', while alpine just says 'Fiber Optic Cable'. I am assuming that that they are the same and you went directly from you sound card into the digital 'headunit' input on the proccessor.
Is this right?
EDIT: I just answered my own question. You link was broken, but then I noticed the CarDomain link in you signature. Very nice competition system. Very well done, also. I could see the optical cable in your pics. Thank You for taking so many.
