C-J amp with Genesis panels

A customer asked if a C-J 60 watt amp would drive the front panels of his Genesis speakers (not sure which model). He has a separate amp for the bass. Anyone have any experience with this?
Arnie Nudell used an ARC tube amp to voice his IRS and Genesis speakers but I can't remember which model. I'm pretty sure it was quite a bit bigger than 60 watts.

In my experience with the 350's, matching with the bass amp requires something with strong bass. Also, while the ribbons are a fairly easy, purely resistive, 4 ohm load, they do like power.
