In an internal card the analog signal doesn't travel though any busses, it just is generated at the DAC, possibly amplified with a opamp, and then sent to the output connector.
Sorry... my bad english. Well, also it was 3:29 in the morning...
I meant to say... it seems bad having a vulnerable analog signal in a box where there are also numerous and powerful sources of noise present, like pci clock, ata clock, fsb clock, which are not even synchronous or so.
it wouldn't directly affect the analog audio signal i guess, though, since that's in a totally different frequency range. But things like keeping power supply to all components constant, and keeping a clean and stabile clock for d/a could be difficult?
Then again, in the end, a measurement is the only sure answer. So apparently, those lynx people did a hell of a job keeping supplied voltages constant and all that. Thanks for the links!
Edit: well, Maxim Liadov @ digit-life is better at english, and says all i had wanted to say: "Some time ago it was assumed that high-quality sound could not be obtained at all on a computer system because of magnetic pickups from a video card and a processor into the sound card's circuit of the printed-circuit board, terrible power supply from a pulse power supply unit, jitter in converters, ...." But he, too, comes to the conclusion that perhaps it doesn't have to be so.
