Carver's amps operated on the principle of switching the rail voltage, by keeping the rail just slightly above output level, you can maximize the efficiency of a Class AB amplifier.

Switching rail voltage is itself not trivial, that's where the famous "magnetic" part comes in, an inductor is used.

Technically, this is a dancing elephant. The question is not how well the elephant dances, but that it dances at all is a miracle.

I would tend to think this kind of amplifier would not be best for electrostatic speakers having load going down to 2 ohms. I wouldn't even think of using it on my Acoustats, which are known for frying amplifiers not up to the Acoustat specification.

Sound labs have very similar interface to Acoustat. The Sound Labs might be slightly more efficient, possibly about the same as the very rare Acoustat 3+3 model.

Thanks for that Charles. This might sound way off base, but it the amp changes wpc based on the ohms of the speaker, wouldn't the spike up near 10k make the amp less powerful (less wpc) in that region?
