The Pro series iESL is the best way of driving electrostatic headphones.
The Pro series iESL is the best way of driving electrostatic headphones.The iESL Pro driven by either the iCAN Pro or your existing amplifier can go toe-to-toe with the best amplifiers out there for electrostatic headphones. Its defining characteristic is a transparency and an ultra-wide dynamic range that is totally natural.
Imagine that your electrostatic headphones are like the top of the range Porsche. A Porsche engine requires a lot more power than your standard car. So do electrostatic headphones! They need to be ‘charged’ or more accurately, ‘energised.’
Traditional amplifiers do not deliver the either the EHT (extra-high tension) voltage or the required audio voltage that electrostatic headphones need. A special ‘energiser’ is required to ‘energise’ the electrostatic plates in the headphones, typically a maximum output of 300V!
The Pro iESL makes use of 3 core components, all developed using the very best classic approaches combined with the latest in cutting-edge technology, to deliver the ‘perfectly matched’ headphone experience.
