Astell&Kern’s expertise in audio circuit design has allowed us to create a complex and highly integrated circuit chip on a small, six-layer PCB the size of 14 x 41 mm. In order to create a small device, micro resistors and tantalum capacitors, exclusively created for Astell&Kern were used. These same capacitors, which are used by AK DAPs, optimize the audio circuit to suppress power fluctuations, creating a USB DAC that provides stable operation and superb audio performance.The dual CS43198 DACs are paired with an independent analog amplifier, designed to provide true audio playback so you can feel the live, warm and clear sound as intended, without distortion. This is possible based on years of Astell&Kern’s expertise in AMP design. Although it is a small and simple cable type external DAC, it is able to sufficiently drive high impedance headphones with a 2Vrms (Condition No Load) output level.

To make the grip comfortable for one-handed use, the surface was created to be like a pebble that has been smoothly polished by the natural weathering effect of stone, rather than featuring the sharper angles typically found in existing AK products. This product design provides a nice, smooth feeling when holding the cable in your hand.The weight of the metal material used reflects the same durability and solid feel compared to other Astell&Kern devices.
