"Astell & Kern’s digital expertise comes good in this entertaining USB-C cable DAC"

The Astell&Kern USB-C DUAL DAC CABLE has been designed as an extension of existing Astell&Kern DAP lines.Smartphone manufacturers are removing headphone jacks from their products. Without a headphone jack, how do you listen to music on your smartphone with the headphones and earphones you currently own? As streaming services begin to support high-quality, high-resolution audio, are wireless earphones and headphones able to provide the full audio playback experience?

Astell&Kern's development team have set out to create high-quality music playback with dynamic and realistic sound from your computer without an expensive high-end soundcard.

Dedicated Dual DAC with Hi-Fi, Ultra High Resolution Sound
The Astell & Kern USB-C DUAL DAC Cable features two Cirrus Logic CS43198 MasterHIFI DACs which supports native DSD256 and 32bit/384kHz playback.

Small but Powerful Output, Astell & Kern's Signature Sound & Design
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.

Plug & Play with Most Devices
The Astell&Kern USB-C DUAL DAC Cable features a USB-C connection, which can be found on the latest android-based smartphones, Windows and Mac computers.

Since the USB-C DUAL DAC Cable draws power from the playback device it is connected to, there is no need for a sperate charger. The USB-C DUAL DAC Cable supports any headphone or earphone with a 3.5mm connector.
