Class D Amp For 'Stats?

For a number of reasons, I am considering the purchase of a Class D amp (or amps) to drive my Sound Lab A-1s. Most uses of such amps detailed here and elsewhere seem to have been with 'conventional' speakers, which obviously present very different impedance loads than a full range electrostatic (approximately 40 ohms in the bass, dropping to 2 ohms at the highest frequencies). I would be most interested to hear of members' experiences.

Congratulations.

Brian at EssentialAudio (also his A'gon name) has much experience with the JC-1s driving the SL speakers. He also has a lot of experience with the Atmaspheres and the CAT's. So I suspect he would be a good source of advice to get the most out of these.
