Solid, Powerful
Suitable for headphones ranging from 16 to 150 Ohms, the E11K is potent enough to drive all but the most power hungry headphones. Use the low gain setting with high sensitivity IEMs, or switch it to high gain for full size headphones.

Audiophile Grade Design
The E11K offers superior sound quality through expertly selected components and design. Its pre-amplifier section is based on the TI OPA1642, with excellent layering, midrange resolution, and high frequency extension. The power amplifier section relies on the AD8397 for great bass control and smooth drive characteristics.

Sophisticated Bass Boost
A fully discrete bass boost circuit increases output by 3.5dB at 60Hz, producing a gentle swell of low end energy that preserves the overall sound field. The bass boost circuit is completely bypass when off to ensure low noise floor and purity of sound quality.

Craftsmanship
The E11K is handsome with an all aluminum body and chassis. Not only is it solid and sturdy, it also provides superior shielding from EM interference. A knurled volume knob is mated to a smooth turning ALPS potentiometer. Toggle switches are used for enhanced reliability and are easier to operate. A 1400mAh internal battery powers the E11K for up to 16 hours of use.
