Thanks Nick, that's the other point I wanted to make. Whether you use PT or DP, the DIGI002 would be an effective way to get audio in and out.
I don't think it the BEST..RME hardware or Apogee is the way I would go. But the WZAD96 or a pre as I'm using, Focusrite ISA220 with A-D takes care of the tracking and recording with quality.
