Many audio cards have toslink output. My motherboard has
toslink audio out and I'm using that into an outboard DAC.
I haven't had any troubles or any (noticeable) jitter.
Can't really recommend any particular audio card.
I also use an external USB DAC/ADC from Edirol
(www.edirol.com).
I'm using the entry level unit, but they make others
which may be better.
The sound is good, but not as good as using my
Musical Fidelity DAC and toslink.
Good luck
TJ
