Roor, why the pre-amp search if you are upgrading your Pass pre-amp? It is my understanding that Nelson Pass creations are best if used together particularly in light of the impedance matching issues.
In terms of pre-amp options, I cannot speak to the BAT or Modwright as I have not heard them in my system. I would consider calling Dan Wright and seeing if any of his pre-amp owners also own Pass amps for more feedback. Otherwise, use your gut and buy something used for a trial.
I am a TRL Dude owner and love that unit, but also use their monoblocks and not Pass Labs. I don't know of any TRL who also owns the Pass Labs amps. The Weitzels might know.
Regarding "pull down resistors," that is simply studio slang for a xlr-rca adapter using a resistors to come up with a "phantom" negative phase. Cardas sells them. Nothing mysterious there.

Almarg, there is no insight there. Just misinformation.
