  • 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 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 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 analogue 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 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.

    * iOS-based devices, such as iPhones and iPads are currently not supported. A dual DAC cable requires more current to run than a single DAC cable. Current iOS devices limit the amount of current exported and so don’t provide enough current to power a dual DAC configuration.
