I would join Jonnyb53 with his recommendation. If to use passive preamp then transformer based. I have had good experience with Promethius (spelling...) Ref 3. It was much better (and cheaper) then famed Placette
Still, I wish to point out that not a singke passive preamp was as good as high quality active preamps (I use tubed ones only) not inresoultion and detail - despite many testimonials and never ever dynamic range and bass extension.
Good Luck
