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.

Never mind Distephenson. Either he has limited experience with this new genre, or an inhospitable system hindering their proper function.

See my system review, at:

One will run into a lot of pitfalls when trying to implement the H2O (I have the Sig monos). For me, there is no doubt they are the best amps I have ever had in my system.

I have found any speaker cable that has anything but minimal insulation coating will cause dielectric polluting of the signal. Also, I am a fast non-upsampling convert. Preamps with a strong power supply do better.

This is a new technology, and that applies to all digital, and class D amps. It requires a rethink of system priorities to bring out the best. The potential is there.
Art, I imagine you forgot my speakers have an impedance of eight tenths of an ohm. One H2O owning fellow I know is trying out his on new ultra light ribbons at .4 ohms, and likes very much what he is hearing.
Unsound, you may have a good point. Apogees have historically been known as downward tilting sounding speakers, especially the Scintilla.

However, "bright" is a symptom I can't abide. I detest any sort of distortion. My speaker's highs are as sweet as a soft center Sees candy.

Currient11, Enjoy your Soundlabs. If there is anything I have learned, there are many avenues to enjoyment of music.
