The advice for a good USB converter is sound, however it requires that you jump through some hoops for the computer.
Rather than doing this, Just add a Synchro-Mesh reclocker to the digital feed from the PCI card and drive the DAC with the SM. Reducing jitter is what is needed and the SM will do this for you. It will even improve MP3. Relocating the clock that is used for master clock from the computer to a more controlled environment is the ticket. The SM does this for you. you can also upgrade the power supply to a Dynamo, which makes an even bigger difference. The SM can be used for reclocking your PCI card, a Sonos or even a CD transport.
