Quad vs. Martin Logan?


How does Quad and Martin Logan compare? How about other Electrostat manufactures Innersound, Magnepan etc?

I have heard great things about Quad and the company seems to have a great tradition. Did Quad create Electrostat technology? I have no dealer close to me (far, far away) and I would like to have some feedback so that I might plan an audition when traveling soon.

Thanks for sharing your time!

Electrostats really have that victorian look to them - plus the open voltage. It's ALliiive...
Though I admire Maggies, once my ear latched onto the "stretched tight plastic film midbass" sound, it's been hard to overlook it. But some listeners find that sound attractive (drum head like tightness, maybe) and enjoy it. No moving coil system sounds anything close to that, no matter its size or price. So IMO, the taunt tympanic diaphragm is creating its own sound. Again, Maggies are deserving of their admiration (I tip my hat to their excellent American made innovative heritage) but that one weakness keeps me from enjoying them. Their ribbon tweeter is superb.
For my part, and based upon the Electrostatic speakers that I have operated over the years, I would, personally, place them in the following order of fidelity.

A. Martin Logan CLX (with and without Descenti's to taste), Sound Lab A-1/U2, Quad ESL 57.

B. Quad ESL 2905/2812, KingSound King III.

C. Quad ESL 63.

I retain the ML CLX Aniversary/Descenti combo and a couple of pairs of ESL 57's.
