Bridged amp with electrostatics..


Is there any problem to use bridged amplification power with electrostatics?
I've heard that bridge amplifiers are very powerful but they can't see an impedance load very well.
Are there any other problems with this match?

"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.
That's right Gregadd, the amp in question is the MF KW500 integrated and it is built in as bridged...I still look for sombody that has a bridged amplifier/s that uses for electrostatics, what are the precautions?
Thanks all of you.
Sorry I may bring some confusion; I am keen to buy a MF KW amplifier, there are two models. One is integrated delivering 650W and theother is a power amplifier only delivering 750W; both are bridged per se,by design and non-reversable.
My speakers are Martin Logan SL3; I don't mean blow the speaker by too much power (altough it may occour).
I don't understand why it is not safe to have grounded tweeters or crossovers when using a pair of bridged amplifiers.
I think electrostatics are grounded speakers, yes?
So, what to do to use them both?
Thanks...
Hi Ngiockey, I want to use some amp from Musical Fidelity KW range,as I already own a KW DM source system to great effect; my speakers are Martin Logan SL3's.
Reading some reviews of KW 550 amp,the reviewer says not to ground the loudspeakers using that particular amp or there will be a massive failure.
I don't understand what he does mean by that, any suggestion will help.
Thanks
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
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!
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
