OP,
Reading through this thread it seems that you are reading reviews, listening to advice from others, and looking at specs for components.
My suggestion is that you call Reno HiFi. They have new, used and demo product from Pass. They allow you to demo, and return if not satisfied. Get a Pass preamp and try it in your system.
I don't own any Pass (I have an Aesthetix preamp and amp), but you already have the Pass amp, so I would recommend trying a Pass preamp.
Good luck with your search.
