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.

Dlstephenson,

Can you tell me what amps you have heard? What you seem to be describing is quite different to my own experiences. thanks.
Nealhood,

I fully understand your comments on the Atmas. I have owned both the S-30 and the M-60s in the past (not for the SoundLabs, obviously). However, the biggest single push towards the possibility of the Class D amps is the ability to leave them on at all times. You see, what I did not explain was that, at this time, I'm pretty much forced to listen in short intervals of an hour or less. No amp is going to sound anywhere near its best for least 1/2 hour after a start from cold. I'm just plain tired of having to shut things down at the same time things are starting to sound good.
Warnerwh,

I have also owned the Innersound ESL (driving the Eros, as a matter of fact). I think it's a very good amp, and - especially used - a fantastic value. What I never got from the ESL was the harmonic richness of tubes, something I value highly. A couple of reviews of the various Class D amps have suggested that that richness is characteristic to a degree. Here, I'm specifically thinking of Srajan Ebaen's review of the H2Os. Coming from a long time tube addict such as Srajan, I found his comments to be rather striking.
Jafox,

Now that's what I needed - a directly applicable opinion. I wonder if the H2O M250 Signatures would be better? These are actually my top contenders at the moment. The CATs are great amps, but they have the same downside as any other tube amp for me at this point in time (see above). With all due respect to Harrahlv, Bryston is not my particular cup of tea either. I actually have 3 'conventional' solid state candidates for amplification as well - Ayre V-1xe, Edge NL-12, and McCormack DNA-500. This may be a long road.....
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.
