If I'm reading right, you need a USB interface w/ SPdif out, capable of 24/96 out. I imagine there are a ton of them, all the way from the Hilo Lynx (which you would want to use their headphone out, I imagine). Browsing Sweetwater, the lowest priced spdif output interface I saw that I would trust was the Roland Quad Capture. That is about a 10th of the Lynx price ($250). There are plenty of choices inbetween.
Also, for the sake of the OP, lets not turn this one into a sample rate thread. The man wants to work at 96 rate.
