i owned Tenor OTLs for three years with Kharma Exquisites. in fact, back in 2001 i was the first person that matched Kharma and Tenor. It was and is an ideal match. simple speaker with very minimalist crossover meets simple amp without an output transformer.
during my time with this great match i likely tried 10 or so active preamps in my system. i never found anything that improved on a resistive based passive. i used the Placette RVC. the Placette is so cheap i would highly recommend starting with one and then comparing it to some active preamps.
the purity of the Kharma/Tenor match will challenge any preamp to be as un-colored....to my ears no active preamp availible at that time could do that. to my ears the ARC pre would not be my choice...but it might be perfect for you.
it's possible that my current preamp; the darTZeel NHB-18NS might likely be one active pre that would improve on the passive but it's alot more money.
good luck.
