The AK380 high-definition audio player was designed with the objective of meeting the demands of professional music lovers. Accordingly, it includes high-end features such as a 32 bit / 384 kHz converter or a 20-band equaliser which can be adjusted in 0.1 dB steps. Moreover, the audio player is capable of playing any kind of audio format and can be extensively adjusted to personal preferences. The design hints at the particular features of the player: it was inspired by the interplay of light and shadow, which is meant to symbolise the motion of light and the finite nature of time.
