The audio stored on a dtsCD is formatted as 2-channel, 16-bit, 44.1 kHz PCM -- that is, the dts stream is [if you will] camouflaged as a regular Red Book stream in order to get on the CD or LD in the first place. If I record that digitally, the .WAV file will contain the pseudo-audio data, and if it's not resampled or otherwise processed it can be played back as DTS. [Note: playing back through a normal DAC as PCM results in a truly evil "black noise" which can damage equipment.]
Anyway, I'm not looking for a digital-analog convertor, or an analog-digital convertor, because I'm not trying to playback digital files to analog audio or record analog audio to digital files. I can already do those things. What I want to do is catch a PCM stream via SPDIF and dump it to a .WAV file -- digital to digital. For that, I need [I think!] a soundcard with a digital input.
