" I am looking for a good sound card with s/pdif output for stereo playback..."
Look at RME Hammerfall DSP 9632 soundcard. ( http://www.rme-audio.com/english/hdsp/hdsp9632.htm ) The RME, a 192kHz-capable DAC, provides output to both the analog and S/PDIF jacks - exactly as you wish.
Its not cheap - I believe its priced at about $500 but its very good
