Speakers for low power amps?

I don't know if they're available south of the border, but FAB speakers, especially the 97db efficient Model 1, are a lead-pipe cinch for low-power tubes. I'm toying with the idea of getting a pair to replace my Coincident Total Victories - looking to get a close to a "SET-driven electrostatic" as possible.

I have a pair of C&C Abbys, but for all that they do well they lack too much in the dynamics, extension and neutrality departments for me to consider them a serious speaker.

I've heard the FAB Model 1 at my hi-fi pusher's store, driven by my Wavelengths. They sounded fantastic - open, clean and very dynamic with great bass slam and faster than Anna Nicole Smith. The amps matched those speakers much better than my big Coincidents - even at a claimed 97db and a realistic 93, those 9 drivers per side need more current than the Tritons put out. The FAB 1's could be driven off a headphone amp...
