Hi Isamu,
If your soundcard has a 1/8" stereo jack, you can use the Audiopath Silver iPod cable.
Let's say I have a KILLER sound card like the 1616M by E-MU and have it hooked up in my car to the *The Soundgate ALMBAUX* for my Mercedes via the AudioPatch Cable...will it improve the sound over a simple $10 Radio Shack cable?
YES!
Best regards,
Vinnie
