Conventional amplifiers have serious problems when forced to drive electrostatic loudspeakers. Roger Sanders has developed the first amplifier specifically designed to drive these unusual speakers. Electrostatic loudspeakers (ESLs) are very different from conventional magnetic speakers and place unusual and difficult demands on the way amplifiers deliver power to them.A magnetic speaker presents a resistive/inductive load to an amplifier, while an ESL appears mostly as a capacitor. We have developed both the ESL amplifier and the Magtech amplifier to meet these demands.Our new pre-amplifier has been designed to match the faceplates of our amplifiers.
