We, Phasemation, released the Pure Audio Grade Headphone Amplifier, EPA-007x. Phasemation has been releasing the audio equipment for reproducing live music consistently. Also for EPA-007x, we aspire to have pure audio grade sound quality by adopting the high-quality sound technology specialized to music playback utilized to other Phasemation products.

This amplifier is compatible for balanced headphones due to the dual monaural construction. Unprecedented natural lateralization is provided by the recently-developed dump controller.

Product Concept

Main feature

1. Dual Mono Amplifiers consisting of Discrete Components in All Stages

High-sensitive headphones reflect sensitively in the freshness reduced by passing through devices. In EPA-007x, an operating amplifier is not used in order to prevent reducing freshness; so carefully-screened devices are adopted in all stages. The dual amplifiers have independent power supplies; therefore balanced cable type headphones
Completely separating L and R lines can be driven.

2. Adopting Damp Controller for Providing the Damping Force to Headphones

The damping force matching the headphones having on impedance variation of 16 to 500 ohms can be set by the damp controller adopted in EPA007x. In addition to contact degree of the head pad, by driving the headphones with an appropriate damping force, a pesante bass tone can be created; and the audio image existing at the head point is moderately alleviated; therefore your stress can be alleviated when listening for a long time.

3. Adopting the Protection circuit for Protecting Headphones

The cut-off protector which prevents propagating pop noises generated when the power switch is set ON/OFF and protects the headphones in an abnormal action is adopted.

4. Resonance-free, vibration-free and interference-free chassis made of aluminum in all

The unit consists of the front panel made of aluminum steel shavings to be a nonmagnetic material, (the 2mm thick chassis and top cover.) By exhausting heat from the chassis faces, the enclosed structure without slits is achieved.
