Meet Astell&Kern's new sonic sensation

AK USB

Astell&Kern, the global leader in premium portable high-resolution audio devices, introduces the AK USB-C Dual DAC Cable, enabling music fans to experience the best sound quality possible from a computer or mobile device, while on-the-move. Joining the company's line-up of award-winning portable digital audio players (DAPs) and headphones, this ultra-compact audio accessory will transform the sonic performance from an Android smartphone, Windows 10 PC, tablet PC or MacOS computer.

With leading smartphone manufacturers continually omitting headphones jacks and including low-performance DACs, and with popular streaming services offering high-resolution quality tracks, enjoying high-quality music playback on-the-go or on your desktop is becoming increasingly difficult. This is where the AK USB-C Dual DAC Cable becomes an essential audio accessory: Plug the dual DAC cable into the USB-C input on your device, connect a pair of 3.5mm headphones and immerse yourself in dynamic and detailed sounds.

DUAL DAC

At the heart of the Astell&Kern AK USB-C DUAL DAC Cable sit two Cirrus Logic CS43198 MasterHIFi™ DACs which support high-resolution audio playback up to native DSD256 and 32bit/384kHz. With years of expertise in audio circuit and amplifier design, the company was able create a complex and highly integrated circuit design to fit into a diminutive, chewing gum packet-sized (17mm x 50mm x 10.3mm) chassis. Elsewhere, Astell&Kern's bespoke designed capacitors, that also feature in its range of high-performance DAPs, optimise the audio circuit to suppress power fluctuations and provide stable operation and best-in-class audio performance all from an ultra-portable housing.

The dual DACs are paired with an independent analog amplifier, designed to deliver a distortion free, live, warm and clear sound as the artist intended, while harbouring power to sufficiently drive a variety of high impedance headphones with a 2Vrms (Condition No Load) output level.

NOISE-SHIELDED CABLE

A custom-made, durable, 4-core cable is designed to withstand the vagaries of life on-the-go and to reduce signal interference for the cleanest audio possible. With Technora aramid fibre at its core to block external noise, thick silver-plated copper is wrapped around this centre strand, with a further layer of copper added in a spiral arrangement. The addition of copper wire helps to affect a clear and rich spatial sound, while separate shielding treatment is applied to the cable to block distortion and digital and analogue signal noise from the playback device.

PREMIUM DESIGN

As you would expect from an Astell&Kern the device, the AK USB-C Dual DAC Cable boasts a stunning, angled surface design that follows the 'light and shadow' concept employed throughout all Astell&Kern products. The smooth, polished metal zinc alloy body offers a reassuring premium feel and bulletproof protection for life on-the-road.

The Astell&Kern AK USB-C Dual DAC Cable is priced £109 and will be available from April from www.astellkern.co.uk
