Astell&Kern AK HC2 (featured)

Editor’s brief: Plugging your wireless headphones into your device is the simplest foot forward for audio, but sometimes you want extra oomph. So, some of us would use a wired heaphone instead. And for the added punch, why not plug something like a Astell&Kern HC2 Dual DAC cable and get even better audio you deserve? Read more below.

SINGAPORE – The AK HC2 Dual DAC Cable from Astell&Kern is an uncompromising and ultra-compact way to transform the audio of your iOS and Android smartphone and tablet, as well as your Windows or Apple laptop. This portable DAC is the successor to the PEE51(AK HC1), and it features a balanced 4.4mm jack for headphones, allowing audiophiles and music lovers to connect their high-resolution headphones without any hiccups.

Making the most of the high-resolution audio offered by the most popular streaming services may not appear straightforward due to the fact that digital-to-analogue conversion circuitry in laptops, tablets, and smartphones remains a secondary focus, and headphone jacks are becoming a rarity in smartphones. However, this is now possible, and the AK HC2 is the tool that will get the job done quickly and efficiently.

Superior Dual DAC, circuit design

Astell&Kern’s award-winning A&norma series of digital audio players, which feature Cirrus Logic CS43198 MasterHiFi DACs, are at the heart of the AK HC2 Dual DAC Cable. These DACs are capable of playing high-resolution audio up to native 32bit/384kHz and DSD256.

A high-performance analogue amplifier is paired with the dual DACs, making it possible to drive even high-impedance headphones with ease. Additionally, the 4.4mm balanced output ensures lower noise, higher output, and clearer channel-separation in every situation. Custom capacitors improve the audio circuit by dampening power fluctuations, boosting the quality of the output, and reducing the power needs of the host device.

Durable, dual-shielded cable design

The digital-to-analog converter (DAC) of most USB DAC products is physically located in the USB terminal, allowing for direct connection between the device and the DAC for audio processing and output. However, with the AK HC2, digital signals from the device travel through the dual-shielded cable to the audio circuit, where they are processed by the DAC before being output as an analog signal. The sound quality is better than that of competing USB DAC products thanks to the delayed digital signal processing.

A dual-shielded cable is built to eliminate outside noise and provide as uncolored an audio signal as possible. The woven cable is wrapped in an aluminum film to help block noise, a persistent issue in audio playback, and the copper core wire is coated with tin to prevent corrosion and strengthen tensile force, increasing durability.

Roon Tested

The AK HC2 is Roon Tested, meaning that subscribers can take advantage of Roon’s management and sonic features; users can also adjust the volume with the help of a specialized Android control app, which is a nice touch.

Light and shadow design

The AK HC2 keeps with the unique and recognizable aesthetic of other Astell&Kern products. A polished and sturdy aluminum body guarantees durability and a premium feel and build, while the angled surface mimics the ‘light and shadow’ vocabulary found across the Astell&Kern product line.
