AK380 AMP vs. Other AMP


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.
