Not heard Pass, but I own the Plinius SA102. In Class A, it's amazing what kind of projection it gives the electrostats I have. It's a great amp and one that you should keep an eye out for. Audition both and decide.
THe cool thing about the Plinius is the toggle switch that allows for A/B bias for regular, background listening... and Class A bias for critical listening.
And the switch will pull in the "fuzzies" from around the vocal image inwards to a sort of dense ball of vocal focus and pull out the singer a bit more forward while distancing the drums further in the back... it's a real cool aural phenomenon when you have someone else switch the Class A bias on while you're listening in the listening chair.
