  What kind of power wakes up electrostatic speakers
Is it wpc, high current, both or what? I've been aud-itioning amps with the Final Electrostatic 0.3's (86 db sensitivity). The manufacturer suggests a minimum of 50 wpc to get them going. So far, I've tried a Nakamichi Stasis (150wpc) and an Electrocompaniet AW250DMB(250 wpc).With both,the speakers sounded dull, yet the Parasound HCA 3500 (250wpc & high current)made them sing sweet as can be.
Could somebody be kind enought to explain to me how this stuff works. I need to purchase an amp to drive the Final 0.4's (the big brother to the 0.3's). I'd love to know what
to look for.
I appreciate in advance your help. The source for this
was a Pioneer PD S95.

Greetings Steakster -

Congrats on you Final purchase! That's one of the few electrostats I haven't heard.

First of all, the Nakamichi Stasis is prone to going into oscillation and self-destructing when driving electrostats. Nakamichi skimped on the output transistors and didn't use the ones designer Nelson Pass specified.

The thing an electrostatic panel likes is a high voltage amplifier. Don't worry too much about the ultra-low impedance at high frequencies (unless your amp is oscillation-prone like the Nak), as there is very little energy up there. It's the high impedance at the lower end of the panel's range, plus the capacitive load, that gives many amps a severe pain in the output stage.

Nearly all of the speakers I sell are full-range electrostats, and by far the best bang-for-the-buck amp I've found is the InnerSound ESL amplifier (good call, Bart!). If you don't have a local dealer, shoot me an e-mail and I'd be happy to arrange a no-risk in-home audition. By no-risk, I mean if you don't like the amp, you won't even have to pay the return shipping.

Best of luck to you in your search!

Duke
