Astell & Kern PEE51 USB-C Dual DAC Cable
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?
How can you enjoy high-quality music playback or games with dynamic and realistic sound on your computer without an expensive high-end sound card?
The Astell&Kern development team set out to create a product that would answer these questions.
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.
With the USB-C DUAL DAC Cable, you can experience premium, high-resolution audio from your computer or mobile device.
Small But Powerful Output, Astell&Kern’s Signature Sound and Design
Astell&Kern’s expertise in audio circuit design has allowed them 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, optimise 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 and 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 separate charger. The USB-C DUAL DAC Cable supports any headphone or earphone with a 3.5mm connector.
The USB-C DUAL DAC Cable brings the famous signature Astell&Kern sound to your devices for a reasonable price.
- Both earphones and headphones that support 3-pole and 4-pole 3.5mm plugs can be used, but the in-line controller and microphone functions built into 4-pole earphones and headphones are not supported.
Noise-Shielded Customised Cable
Astell&Kern developed a custom-made, 4-core cable to express the sound you want to reveal through the cable and enhance durability against disconnection. The cable is reinforced to withstand up to 200N of tensile force using aramid fibre.
This cable is made by wrapping silver-plated copper wire and the copper wire in a spiral form around a center core made of Technora Aramid fibre to block external noise.
A separate shielding treatment is applied to the cable to block distortion and noise of digital and analog signals from the playback device.
The silver-plated copper wire used in the USB-C DUAL DAC Cable is thicker than typical silver-plated copper wire (0.3μm, usually 0.1~0.15µm). The addition of copper wire provides clear and rich spatial sound.
The USB-C DUAL DAC Cable uses the design concept of “light and shadow” that is used in all Astell&Kern products. The USB-C DUAL DAC Cable design is based on a single centerline that boldly crosses from right to left. The faces were arranged by adjusting the angle ratio so that the sharp faces of the upper four faces meet at one point. It is designed so that each side is reflected according to the movement of light.
To make the grip comfortable for one-handed use, the surface was created to be like a pebble that has been smoothly polished by the natural weathering effect of stone, rather than featuring the sharper angles typically found in existing AK products. This product design provides a nice, smooth feeling when holding the cable in your hand.
The weight of the metal material used reflects the same durability and solid feel compared to other Astell&Kern devices.
