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.

It's been suggested that speaker impedance variation with frequency might affect operation of the output filter of digital amps. Perhaps that explains why Magneplanar speakers, with their flat resistive impedance, respond so well to powerful digital amplifiers.
