For what it's worth, Emmanual Go, producer of the superb lineup of First Sound tube preamps initially marketed a passive preamp. Eventually he began to engineer, manufacture, and sell dual mono actives with separate power supplies. I recently paid Mr. Go to install the two "S" upgrades in my FSPD III and an incredibly quiet, dynamic, and musical preamp jumped yet another notch in performance. It is the only component I've owned during 45 engaged in this hobby that I've never considered selling.
I used to think passive preamps were superior to active preamps given right the setup, but
my recent evaluation of a modded old SS preamp has me a little befuddled. I've evaluated $10K+ active preamps in the past and was never impressed especially given their cost. In general, I've found passives to do better job. I know there's ongoing debate on this. But here's a very illuminating video on the subject by Bascom King, one of the legends of high end audio.
