The Pro Series iESL electrostatic headphone amplifier from iFi AUDIO
offers transparency and an ultra-wide frequency range. It works with all
Stax, Sennheiser Orpheus, and electrostatic headphones.
Drive Your Electrostatic Headphones to the Max and Use with a Headphone Amp:
iFi Pro iESL Energizer Charges Your 'Phones, Supplies Needed Extra
Voltage, Yields Incredible Transparency
Drive your electrostatic headphones with the iFi Pro iESL Electrostatic Headphone Energizer and experience the phenomenal transparency, ultra-wide dynamics, and
natural musicality for which the style is renowned. Offering perfect
bias, impedance, and termination matching with every electrostatic
‘phone around, Pro iESL paired with a high-end
headphone amplifier supplies the proper extra-high-tension voltage
required by electrostatic headphones – something conventional amplifiers
cannot offer. Pro iESL "energizes" the electrostatic
plates in your ‘phones, giving them the power they need to operate at
peak potential. A hand-wound permalloy core transformer, capacitive
battery supply, and bias voltage generator do the work so all you have
to do is listen to what you've been missing. iFi Pro iESL is the flagship your electrostatic need and deserve. 100% Music Direct Guaranteed.
Please note: iFi Pro iESL is strictly for use with electrostatic headphones and needs to be paired with a headphone amplifier.

Pinstripe Permalloy Core Transformer (PPCT) Making a transformer with the wide bandwidth and low distortion needed in iESL
makes for a very challenging proposition. iESL's custom transformers
use complicated hand-wound, multi-section windings with vertical and
horizontal sectioning. They exceed the standards set by Siemans
(Germany) and Peerless (USA). With a bandwidth of < 5Hz to > 60kHz
(-3dB), transformers in the iESL far exceed the requirements of even
the JAS High-Res Logo.
Capacitive Battery Power Supply The battery supply is always 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. It's an essentially perfect
bias voltage source with no electronic noise at any frequency. The
headphones are, in essence, powered by the battery bank and not the
mains.
Wima Capacitors
German made, 1,000-volt rated Wima capacitors feature high insulation resistance and
minimal current leakage. The whole capacitor pack has around 35,000,000
kiloOhm insulation resistance, meaning that self-discharge time (to
30%) is around 100,000 seconds, or 27 hours. This allows you to always
listen on battery (not mains) power.
Vishay MELF Resistors
MELF's offer superior SMD resistor performance in terms of accuracy,
stability, reliability, and pulse load capability. Cylindrical
construction provides the optimal power rating and pulse load capability
need for iESL.
