iQube Portable Headphone Amp V1

$449.00

North & South America Sales Only.

The iQube headphone amp version 1 is a lightweight, high efficiency (90-95%) Class D amplifier that runs on 4 AAA alkaline or rechargeable batteries. It has a user replaceable 8-fold output buffer for a (near to) load independent output behavior with a 4th order feedback loop for minimum distortion.

It also includes a fixed, phase-shifted carrier wave oscillator that decreases inter-channel distortion. The ultra low noise front end accepts any line level source without the need for impedance matching and top A-grade components are used.
