Since electrostatic headphones needs to be charged or energized, iFi has came up with a product. The Pro iESL is an electrostatic headphone driver that has transparent characteristic and wide dynamic range that is totally natural. Since, traditional amplifiers do not deliver either EHT (extra-high tension) voltage or the required audio voltage that electrostatic headphones need, such amplifiers are needed. The Pro iESL makes use of the 3 core components, all developed using the best classic approaches combined with the latest technology to deliver a perfectly matched headphone experience.
The custom transformers use had-wound, multi section windings with both vertical and horizontal sectioning with a bandwidth of < 5Hz to > 60kHz (-3dB). The capacitive battery power supply are charged up to the required voltage and then the charger circuit is turned off completely, leaving the capacitor bank to float at the required bias voltage with no electronic noise at any frequency as the headphones are powered by the battery bank and not the mains. The iESL includes quality components like Wima Capacitors, Vishay MELF resistors and much more. The device can also be used to elevated the performance of flagship dynamic headphones resulting in a much higher level of smoothness and airiness.
