Mike, That is exactly the question. I would think that the onboard S/PDIF output would pass the original signal, regardless of how well the unit can decode the signal. Meaning, there is no point to paying more $$ for a higher end audio card when its only a pass thru to the external receiver; which is of very good quality. So is this logic correct? If so, I can partially dismiss this Asus criticism. I'd rather not have to tie up a pci slot for audio if I can help it. Maybe this is a bigger topic than I thought...
