tube amps and electrostatics

Just checked with two experienced sources. Your amp will work fine with Original Quads - use the 4-ohm tap.

Dabble, I believe your amplifier would work well with most hybrids, but not necessarily with full range electrostatics. The reason is that full range electrostatics usually have a very high impedance in the bass, often over 50 ohms, and your amp would not put out much power into this load and so would clip prematurely. Electrostatics typically have a very low impedance at high frequencies, but with the CJ this shouldn't cause a significant frequency response anomaly. And remember there is relatively little energy up around 20 kHz, so the amp is not likely to clip as a consequence. I sell Sound Lab electrostatics, and they have a couple of hybrids that would work with your amp. I think the Martin Logan and Inner Sound hybrids would work well also. Avoid used Acoustats or Martin CLS's as they will give your amps a severe pain in the output stage. Historically Connie J. EL-34 based amps work well with Quad 63's (& USA Monitors), which are full range electrostats. I have a few reservations about these Quads, however, and personally prefer the Originals. But, I have no experience driving the Originals with EL-34 based amps, so while I think it would work I don't really know. I'd like to ask some specific questions that might help me make a more educated recommendation. Don't worry, I'm not going to push my product at you. I am one of you, not one of them.
