Snopro,
I run a pair of Zu Audio Essences with my Manley 300b amplifiers. I run my amps single ended, meaning they put out 11 watts. The Essences are not as efficient as the Druids, still, the Manley amps drive them with gusto. You should not have any problem driving the Druids with the Frankensteins. You should be able to listen at your preferred volume levels and still have plenty of headroom left.
I don't know if you have considered this, but I strongly suggest you acquire a Zu subwoofer with the Druids. I use a Zu Mini-Method with my Essence speakers. Zu subs are lightning quick and integrate seamlessly with speakers. My Mini-Method sub is an integral part of the system. It is key in delivering a full spectrum presentation of the acoustic image. I could not live without it.
