I have not had time to read "The Art of Electronics" yet so I need your help.
What do the 2 large sets of caps do in the DAC?
I was comtemplating changing the ps to a STEPS before it arrived (b/c I assumed it to use DC in the range of 12-24v), but this thing puts AC into the pcb at 3 different points if I'm interpreting it right, so STEPS is out...correct?. Is a power supply upgrade an option? Can someone explain this "3 way" ps relative to a DC ps. The specs for the ps are:
Transformer: High quality R-Core
Power supply: 3 regulated isolated power supplies
It's been modified to use socketed op-amps (Burr-Brown OPA627 now) and Black Gate coupling caps. What are coupling caps and why is it nice to have BG-NX caps there?
Here is the schematic link (obviously I can't read it very well
):

Thanks for your help,
