Hi Snopro,
I have used the Frankensteins Mk2 with my Zu Def Mk4's for several months. The Franks were revelatory for me in this system. I was using Atma-Sphere M-60's. The tone density, palpability, 3D imaging, micro dynamic shadings, and overall coherence (space and musicians cut from a single cloth) were all improved. Transparency is also very very high. Unless you routinely hit peak SPL's greater than 105, you won't even think about not having enough power. I'd be far more worried about hearing loss if those SPL's were normal for your listening sessions.
The Franks are top notch amps (and extraordinary values) that I would continue to use if only I hadn't stumbled on a little better match for my system, Audion Black Shadows.
