AK HC2 Dual DAC Cable

Introducing the AK HC2 Dual DAC Cable, an uncompromising and ultra-compact way of transforming the audio of your iOS and Android smartphone and tablet and Windows or Apple laptop computer.

Following on from the AK HC1 (PEE51), this portable DAC arrives with a 4.4mm balanced headphone connection so audiophiles and music fans can seamlessly drive their high-resolution headphones of choice and experience original studio-quality sounds, whether on-the-move or listening from a desktop.


Despite measuring just 17mm x 50mm x 10mm, the AK HC2 USB-C Dual DAC is packed with cutting-edge features, carefully designed to deliver high-quality, low-noise sonics via its 4.4mm balanced headphone output.

Ultra-fine audio technology means Astell&Kern has been able to incorporate circuitry, components and power management in a supremely portable device without concession.

Superior dual DAC

At the heart of the Dual DAC Cable are two Cirrus Logic CS43198 MasterHiFi DACs – high-performance DACs that feature in Astell&Kern’s award-winning A&norma range of digital audio players, and support hi-res playback up to native 32bit/384kHz and DSD256.

DAC smarts

Most USB DAC products have the DAC positioned in the USB terminal connected directly to the device to process and output audio.

However, with the AK HC2, digital signals from the device pass through the dual-shielded cable to the audio circuit before being converted to an analogue signal by the DAC.

By processing the digital signal at a later stage, the sound performance is superior and noise-free sound compared to other USB DAC products.

Drives any headphones

The dual DACs are paired with a high-performance analogue amplifier, powerful enough to drive even high-impedance headphones without difficulty – and the 4.4mm balanced output means lower noise, higher output and clearer channel-separation every time.

Noise-free cable

A dual-shielded cable is designed to minimize noise interference and deliver a transparent sound as possible.

The copper core wire is coated with tin to prevent corrosion and strengthen tensile force for enhanced durability, while the woven cable is wrapped in an aluminum film to help block unwanted noise.

Astell&Kern is the ultimate Hi-Fi audio system

Astell&Kern is the ultimate digital music source that brings you Mastering Quality Sound or MQS. Astell means ‘Stars’ in Latin and Kern means ‘Center’ in German. We believe Astell&Kern is the center of music. Today, original music performances can be captured in digital almost exactly as they were performed due to new, advanced recording technology currently available. However, these high quality recordings are mainly listened to through inferior sound formats, such as MP3 or through streaming services. With the debut of the MP3 format, music lovers sacrificed sound quality for the convenience of being able to carry their music collection wherever they went. Because the MP3 format heavily compresses files for the sake of convenience, the vocals and instruments you hear are only an inferior version of the original. The soundstage and the ambience of the original performance often disappears when listening to compressed MP3 music. After pondering these issues, Astell&Kern was our solution to poor sound quality for the sake of portability, and our way in reviving the original sound quality of music, MQS, for music artists, recording engineers, and professionals. Astell&Kern's pursuit is to provide natural and original sound without distortion. It showcases the presence of the original recording with miniscule details you may not have noticed from other music systems, while playing back high-resolution music bit by bit, exactly as it was recorded. The ability to play back the exact recording of any live performance is what Astell&Kern is known for.
