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.
- One-off Pinstripe Permalloy Core Transformer
- Bias Voltage Generator
