Bridged amp with electrostatics..

"With *any* bridged amp, both speaker terminals should be kept from ground."

Hallo Atamasphere, by this you mean I should not ground the main for the speakers, yes?
I'm sorry but I find hard to understand what I should do exactly.
Thanks for the patience.

You can run the speakers with the normal AC ground connection. The concern with most bridged amplifiers is that neither speaker terminal is at ground, so if you connect into a setup that does have one terminal grounded, a potential (pun intended :) exists for damage to the amplifier. The AC ground of your ESLs should have nothing to do with this. I've not heard of an ESL where the AC ground is the same as the '-' speaker terminal, but I suppose it could exist. Check with the manufacturer to be sure.

What ESLs are you using?

All the Best!

Hallo Atamasphere, I own a pair of Martin Logan SL3's with fully re-worked crossovers and re-cabled with Kimber silver cables.
I am planning to have a listen with Musical fidelity gear, their high-range sports bridged amplifiers so before I even think to go for a demo I want to make sure that nothing is going to go to the moon...! Ha ha ha!
However, I don't know how it may sound with the SL3's as they already tend to be on the bright side and I know bridged amplifiers tend to sound very clean, it may be too much for me.
anyway, I suspect I should contact the manufacturer for peace of mind.
We'll see....
Seeya!

The nature of ESLs is such that they have an impedance curve that decreases as frequency increases, causing a transistor amp to make more power in the highs. So you do want to be careful!

I see...thank you for all your time, I got a much better idea now.
I really like this forum, finally a proper place on where to ask for real hi-fi questions.
Ciao
