The Genesis is bi-amped, but the bass amp comes with the system and is an active servo driven system. I've not heard the Wolcott's with this system, but I have heard the Genesis with other amplifiers. I think the tubes would be excellent with the 200s, particularly since the ribbons tend to be a little on the harsh side (201s were improved somewhat). That being said, I do not know the impedance curves of the 200s and you should find them out as Audiokinesis has pointed out.
