digitall2 good reason that both sound good, when using the digital connection on the card (doesn't matter whether it is onboard or a card), the speakers (or whatever you connected to) are doing the decoding, not the card. For the most part the digital connection all comes down to how good the DAC is on the other end.

There is a very long thread (more than one actually) over at guru3d regarding the Auzentech Prelude, and the general consensus it that unless you are connecting to a reasonably high end amp/receiver, you would be better connecting the speakers using the analogue connections as in most cases the DAC on the card is better than the one in the speakers.
