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.

I cannot imagine why you would want a Class D amp? Most class D use large amounts of Feedback to deal with transient response. I have not heard a Class D amp that does not sound mechanical except for subs, this is the one acceptable use that I can think of. What type of music do you listen to?
My experience is limited when it comes to Class D equipment. In the mid 80s I used a ML and enjoyed it, then replaced it with more power, as the dealer that I worked with suggested and traded to a Silver Seven. I really did not notice a change but was happy for quite a while. Just this year I sold all my equipment after listening to a VERY inexpensive Tube amp that was a SE class A. It just sounded more musical, but reality tells me that my hearing is less acute in my late 40s than it was when I was 20. After doing some research on how each class of Amplification works, I can understand why I felt that this tube amp seemed more musical – not more accurate.

Now the real question is why Class D? Perhaps to drive a very difficult load? Perhaps to bring enough power to a large listening room? Or I like the new Rock and Roll?

My question still stands. I really do not understand. But if you would like to give me your reasons for selecting your equipment then I can understand better.

I am certainly outclassed by your GIGA BUCKS system. I would guess it sounds absolutely unbelievable. My experience with SS equipment is obviously less high end. But that does not mean my opinion is less valuable. My object is not to offend but to participate in order to become more Knowledgeable.
