I'm effectivly *designing* a sound card - not in the market to buy one.

I know, but I fail to see the point when there are many affordable USB sound
cards with digital audio inputs and outputs. Plus, I prefer optical digital
connections to keep the electrically noisy PC completely electrically
isolated from my audio equipment.

If I were you I'd concentrate on the high end A/D and D/A parts of the
circuit and use an existing USB sound card with digital inputs and outputs
to drive it.
