Love your electrostatic headphones but need more drive?

Look no further than the iFi audio Pro iESL – this flagship energiser will have them singing in no time.

The Porsche and the Pro

Imagine the audio equivalent of a Porsche engine of the flagship headphone world and you have the Pro iESL.

Electrostatics need high voltages to energise them to make sound. The Pro iESL is one such energiser and delivers the extra-high-tension voltage needed. The capacitor pack has around 35,000,000 kOhm insulation resistance, which means that self-discharge time (to 30%) is around 100,000 seconds or 27 hours.

It is one of the best energisers in the business (even if we do say so ourselves) and is compatible with all the great electrostatic brands – including Orpheus and Koss.

Big sound

If you like electrostatics, then you like ‘big’ sound.

The Pro iESL won’t disappoint. Coupled with our more traditional flagship amplifier, the Pro iCAN (or any other, but we like ours), the Pro iESL lowers distortion, separates vocals, orchestras and instruments.

It opens up the bass and leaves you with a wide, structured soundstage.

Audeze CRBN Electrostatic Headphones

Breakthrough Electrostatic Technology

Featuring the most advanced electrostatic technology in decades, Audeze proudly introduces the CRBN electrostatic headphone (pronounced “carbon”), which features a new Patent-pending polymer film with suspended carbon nanotubes to eliminate problems commonly found in previous electrostatic designs. Originally developed for MRI medical applications, Audeze has adapted those innovations for the audiophile version of CRBN, which top audio professionals have called the best sounding electrostatic headphone to-date.

580 Volt Compatibility

CRBN is compatible with “Stax Pro Bias” 580 Volt amplifiers such those from Woo Audio, Linear Tube Audio, Mjolnir Audio, Headamp, Stax (of course) and others. The cable is terminated with the industry standard 5-pin barrel connector for maximum compatibility.
