Steve and Sean re Electrostatic Speakers
I have built a dozen or so conventional speakers and make no claim to have expertise with ESLs but from what I understand speaker wire is critical with ESLs.
Generally the load presented to an amplifier is completely different for an ESL. ESLs act more like a capacitor in the line while traditional magnetic speakers act like a resistor/inductor.
All cables have inductance, capacitance and impedance and, of course, the amount can be changed by design of the wire. An ESL is driven by a high voltage step up transformer INSIDE THE SPEAKER and it "leaks" inductance. This interacts with the capacitance of the ESL to form what is called L/C (inductance/capacitance) resonant circuit and this will cause a high frequency peak if it is not controlled(kept out of the hearing frequency). They spend a lot of time trying to build great transformers that do not "leak" much. Because inductance is such a big problem due to the L/C problem it is especially important that cables have low inductance too.
To sum it up: If your ESLs' seem to have an unattractive peak in the highs (are "bright") one thing to look at is the design of the cables.
This may seem to some to contradict my prior posts but it does not because well designed cables for ESL's can be had or made for chump change once you know what you are looking for.
as noted, I'm not a big ESL person and if my understanding is off base please give me an e-mail.
