Astell & Kern iRiver AK380 Portable Amplifier is having both excellent conductivity and specific gravity in the body material, the sound of excellent balance with a sense of depth and a sense of weight and possible by the acoustic properties of the copper. 

3,400 mAh Large-capacity Battery
An amplifier, which increases audio output, consumes a great amount of energy. Thus, the AK380 AMP features a 3,400 mAh large-capacity battery – identical to the one in the AK380 itself - to support up to nine hours of continuous unbalanced-output playback.
High Gain
The AK380 AMP supports 8.1 VRMS output when connected via high-gain balanced output. High-gain output is four times greater than low-gain output and supports high-impedance headphones. To protect earphones/headphones during high output, the volume is automatically adjusted when the amp is powered on or the earphones/headphones are disconnected. Furthermore, the gain can be easily adjusted via the AK380's settings.
Integrated Design
The AK380 AMP was designed as an extension of the light and shadow theme of the AK380. Continuing this design concept, the AK380 AMP retains the subtle changes and details in the emitted brilliance as light flows across its surface. The diamond pattern engraved into the volume wheel of AK380 is repeated on the amplifier's rear light for design continuity. The area of the amplifier in contact with the AK380's volume wheel reproduces the design's angle of reflection for comfortable wheel operation. The amplifier's light shining delicately through the gaps in the reflected surface visually accentuate the music’s mystique. Unlike conventional amplifiers, the AK380 AMP was designed from the ground up as a single entity when combined with the AK380. The wheel on the rear of the amplifier that connects the two devices is a representation of the volume wheel seen throughout Astell & Kern products and expresses our unique design identity.
