I was helping out in that room. We had the SA102 biased into class A most of the time - that helped the sound. The Pass stuff is a newer design - no idea vs. which is better.
I have owned the 47Lab gaincard - it's a nice amp that has more power than it's rating suggests. (easily 45wpc instead of rated 25wpc). It will drive most stuff no problem, including full range electrostatics and others. It has a very fast and immediate sound vs. other SS amps.
