    The AK70 is designed with an oblique angle on one side of the body so that it can fit the contour of the user's thumb, the finger used most frequently when controlling the screen with one hand.

    The volume wheel is designed to be protruding slightly from a concave surface so that you can control volume with a simple motion of sliding your finger up and down. With slim 13-mm thickness and 132-gram lightweight, the palm-sized device is easy to carry anywhere.


    The AK70 has adopted a pastel-color anodized aluminum casing, which makes it look high quality with its light mint color and glossy silver tone. The smart-looking exterior and smooth color make the device look more casual and simpler.

    The AK70's DAC, based on market-proven CS4398 chips of Cirrus Logic, has been used for years in Hi-Fi audios and the second-generation Astell&Kern devices. The AK70 plays back 24bit 192kHz signals into bit-to-bit type. 32bit audio is downsampled using a sample-rate converter. In addition, DSD 64/128 can be played back through conversion to PCM.

    • USB DAC

    • Metal Touch Sensor Home Button



    Diverse Output Types - Balanced

    The AK70 supports the 2.5-mm 4-pole balanced output (2.3 Vrms) that has been in use since the second generation of the Astell&Kern players.

    Unlike the unbalanced type, the balanced output type is capable of removing noise (common mode noise) that can occur in “signal + inverting amplifier signal” and has the strength of increasing output due to its double transmitting signals. The AK70 can be used with a variety of balanced earphones and headphones made for Astell&Kern. It can also support the 3.5-mm 3-pole unbalanced output (2.3 Vrms), with compatibility with a variety of Hi-Fi earphones and headphones.


    Diverse Output Type - USB Audio

    The AK70 supports USB audio digital out, first among Astell&Kern devices.

    You can connect diverse digital-input portable amps through USB to the AK70. The AK70 can transfer DSD in native through DoP. It can also convert DSD into PCM for output for portable amps that do not support DoP.

    Diverse Output Types - USB DAC

    The AK70 can be used with a USB DAC that can double as an embedded sound card by connecting with a PC/Mac through the USB port.

    In the case of using the PC's embedded sound card, one may have to go through a complicated process to play back DSD data. In contrast, the AK70 can do so simply by connecting with the PC.

    In the case of using the AK70 as a USB DAC, it can support up to 24-bit 96 kHz bit to bit, providing much richer sound through superior ambience and resolution way beyond the limits of an embedded sound card.

    AK Connect

    Astell&Kern has further enhanced DLNA functionality via the AK Connect app.

    Wireless networking DLNA (version 1.0) connects to a NAS or PC, and is easily controlled with a smartphone or tablet through AK Connect.

    Source files on a PC or NAS can be freely transferred and streamed without the hassle of turning on the computer and physically connecting with a cable.

    If on the same access point (AP) network, music files on a PC or NAS can be played back via DLNA.

    Pressure-sensitive Metal Capacitive Touch

    The AK70 features the same metal touch interface as the AK300, AK320 and AK380.

    The Metal Touch functions as a home key and interfaces with the device via pressure-sensitive touches.
