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.

I have owned stats for 14 years now, Beveridge and Martin Logan. I have made the switch over to tubes and am currently running a Decware Integrated SET @ 7W. Yes, 7W! Gets much louder than it has any right to, not to mention sounding infinately more engaging than the 150W SS amp it replaced. One factor to keep in mind is that most tube amps (Deware is a notable exception) like to drive higher impedance speakers.

Good luck, Paul
Travis, they were sent in for review at the time; they were properly burned in. Coda, Innersound, Boulder are all detailed oriented, energy loaded at the transient-type SS amps - quite similar. Not sure that's a great comparison...

Paul, 7W!!? You've got more courage than me! :0)

Seriously though, Paul, you might find a nice balance with the Berning - and maybe a bit of tube rolling the inputs yo siut.
A friend of mine recently was trying to upgrade the amplifier to drive his Martin Logan CLS speakers, he was driving them with a Quad 606 (original version) and it was sort of managing OK. He was really looking for a substantial upgrade and he tried a Krell 300i which was onsale.

The Krell was not in a position to drive them at realistic levels even at full volume. The Quad somehow was playing much louder and still had room to spare. We were really surprised. Switched his two CD players, three speakers, and the two amps. None of the equipment had any problem including the Krell which was driving the Maggies as well as large dual concentric Tannoy speaker. We were unable to figure out why Krell on Martin Logan CLS sounded like a 25 watter. Nothing made sense to us.

What could be the reason for such low volumes on the CLS? Is Krell 300i a bad match for CLS? Is the power supply of just 400v in Krell not able to cope with the load? Is it the matter of voltage versus current?

Can anyone shed some light on this issue for our better understanding?
Hey, Asa, you heard what you heard. I've never heard the new QUADs so no comment. I'm still glad I found the InnerSound for my 3.6s, though.
