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.

Muralman1, Distortion is distortion, whether it's tilting up, down, or elsewhere. Now if you find particular distortions either more or less objectionable, well, that's something else and all together more understandable. After all that's probably the basis that we all use to put our systems together in the first place. The point I was trying to make was that if digital amps are bright into low impedance loads then in your case it was unlikely to exacerbate the problem and could even help to neutralize one. It may just demonstrate that though opinons vary they may all be correct within given circumstances. It may be that digital amps like other technologies may be specificaly appropriate. Eldartford and A_rt may have identified specific attributes that currently may help in deciding whether or not this technology may be appropriate. Furthermore since this is a relatively new technonlogy we may not have seen all that digital amps have to offer. The future certainly looks interesting.
