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.

The whole issue of low impedance Apogee speakers and the H2O's ability is irrelevant. Since this is not the case for the A1's, discussing an amp that handles sub 1-ohm loads is a "don't care" issue in this thread.

Pure and simple, if you have invested in a $15k speaker like the A1, you need to put the same amount of attention to find an amp of the same calibre to hear what you paid for with the speaker. Again, pure and simple - the H20 does not cut it to convey the many awesome strengths of the SoundLab speakers. We can talk all we want about driveability, but again, this has nothing to do with musicality - the portrayal of space, silence between the notes, dynamic contrasts, ability to play material with a high level of low frequency extension and not have the mids and trebles crumble at the same time, etc., etc., etc.

The CAT amp is not euphonic at all, and the one JL-2 will not generate that much heat. You really should try to hear this to get an idea as to what your speakers are capable of. And try to get the H20 on loan so you can even more greatly appreciate the CAT's ability. Once you hear it, the H20's will be gone.

Thanks to all of you who responded to my questions. The problem has been resolved - at least for now. This morning, I arranged to purchase Bob Crump's personal pair of JC-1s from his estate. For those of you who don't know, Bob lived in Houston, about 40 miles from my home.
Currient11, Enjoy your Soundlabs. If there is anything I have learned, there are many avenues to enjoyment of music.
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.
