Driving 1 ohm

Hi,

I'm actually driving my recently refurbished Acoustat 2+2 electrostatic speakers with a Conrad Johnson MF 2500A. My Acoustats have been completely modernized with new more rigid frame, new electronics in the interface, Medallion transformers and other tweaks.They really get down low with a lot more dynamics than before.

A lot of electrostatics owners will often chose pure Class A amplifiers to drive the load these speakers command. The 2500A plays beautifully and doesn't get very hot at the task.

My question is : am I slowly damaging the amp without noticing it ?

" am I slowly damaging the amp without noticing it ?"

Not really - you do put some additional stress on this amp but if it did not failed during initial period then it was designed properly to deal with the stress so enjoy and don't think about it. If you amplifier will ever fail it will be due to lightening or other 10,000 reasons why amplifier cam fail.

Good Luck

It depends on how loudly you play the amp.

Thanks Simon !

Rwwear, not very loud, we can still speak at normal level while playing music. Most of the time, below half the volume dial on the preamp. But.......even at a moderate volume level, on good recordings, the bass level will drop at a point that a vibration sometimes continuous, can be felt. Those speakers are really something else now. And it is specifically that kind of effect that makes me cautious about the amp.
