I used to run a Wadia 850 direct into a BAT VK60. This was 4 years ago when the 850 was near state of the art. I brought home a BAT VK50se at that time. Wow, an active preamp really improved things for me. Mostly in the area of soundstaging, bass control, robustness of sound.
The BAT also fits your xlr criteria above. Should drive the Pass amps fine (search here, other have posted w/ bat pre's and pass amps-everything seemed fine)
If someone didn't tell you about tubes in the BAT you'd never know it with out looking. About as carefree as it gets. I owned my VK50se for 3-4 years with out any trouble whatso ever. I recentley upgraded it to a 51se and replaced the tubes (plug and play took about 5 minutes total-if you can change a light bulb-you can do this) not sure the tubes did much, after 3 or 4 years the old tubes were just fine.
Your preamp list is all good. They will sound different. You may have to try a few. IMO, you'll be just fine with the BAT.
