Bridged amp with electrostatics..

Although you would like to use Musical Fidelity, maybe a Bryston 14BSST would do the trick. It is bridged and has excellent reviews, class A sterophile, etc Click on www.bryston.ca for imfo and reviews.

I read in one of those reviews that they used the 14 BSST with your SL3's with excellent results. I run ML Oddessey's with a Simaudio moon W-5 , which is an excellent match as well, although it isn't bridged. Hope this helps.

I can't see how it would be possible to bridge an integrated amp like the KW550.

I mean it is already built in bridged...

So are you looking for an amplifier that is based on a bridge circuit then?

Atma-Sphere, BAT, Einstein, Joule Electra are a few that come to mind.

Yes, but they mention not to ground any crossover or tweeter as bridged amplifiers have both red and black terminals "live". I'm confused if I could use an amplifier like that or what I should do to prevent any damage.
Cheers
