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 ?

If they were Apogees or Kappa9's, a rugged SS amp would be the way to go but for ESL's, Ralph is right.

Another option is "monostrapping" or parallelling an identical pair of stereo amps. That would double the current and wattage and halve the output impedance. Some manufacturers don't approve of this method.
