Seems? i work as part of a couple of teams that do a lot of audio based design, digital noise is quite often inaudible. With noise you do need to do measurements to determine the frequency and the source of the noise. Then you can work out whether it is serious and how to combat it.

going from the sound card directly to the TDA1543 NOS dac having common ground will not be too bad?
