A true high current amp will double it's output as speaker impedence halves. Some of the early Krells would double their load all the way to .5ohms. Some of the Apoggees were .5ohms.
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 ?

Rwwear, ESLs do not respond well if the amplifier can double its power as impedance is cut in half. It will result in no bass and too much highs. This is why tube amplifiers are often preferred for ESLs, despite the misguided attempts of several ESL manufacturers of making the speaker's impedance really low in an attempt to make them work better with transistors. The result is often a speaker that neither tubes nor transistors can actually make sound right. For speakers like this tubes and a set of ZEROs are usually the best solution.
