Astell & Kern AK70 MKⅡ

Setting new standards is not new for Astell & Kern, and the newest premium portable audio player AK70 MKII is no exception. Based on the award-winning predecessor, the upgraded AK70 MKII audio player has been equipped with dual DACs and higher audio output while retaining the same smooth and compact design.

Astell & Kern AK70 MKII is the first model in the range to be equipped with a dual DAC at this price-point. Its separated channel circuit design offers less noise and interference, but adds more fidelity and audio output power, to create a bigger soundstage with clearer imaging. The powerful AK70 MKⅡ’s sound quality is sure to please even the most discerning music aficionado.

Superior resolution audio in a pocket-sized portable, AK70 MKII is a must-have for listeners who demand high quality sound any place and any time. The ergonomic body design fits nicely in the palm of the hand, making operation a smooth, one-handed experience.

Portable listening redefined.

Astell & Kern AK70 MKII

High Fidelity Playback
The AK70 MKⅡ plays any resolution of digital files up to 24-bit/192 kHz, bit-for-bit.
32-bit audio and single or double rate DSD can also be played, but it will be converted to PCM or downsampled.

Balanced Listening
The AK70 MKⅡ delivers original sound using the 2.5mm 4-pole balanced output that Astell&Kern first pioneered on the AK240. The balanced out provides a more powerful audio signal with less noise interference.

USB DAC
Connect to your PC/Mac computer, or other systems, via a USB cable and use the AK70 MKⅡ’s hardware to provide better sound quality. The AK70 MKII, when used as a USB DAC, will bring out more detail and provide a better listening experience than your computer is capable of delivering, even when listening to your favourite streaming service.

AK Connect
AK Connect, a DLNA-based music control app, is available on the AK70 MKII and smart devices including your phone or tablet. You can easily control playback, volume, streaming over Wi-Fi and more with this free app from Astell&Kern.
