Astell & Kern AK70 MKII 64GB Silver Portable Hi-Res Music Player. Available with Online Finance and Free Delivery.
The AK70 has been reborn as the AK70 MK2 through Astell&Kern's accumulated know-how.
The advantage of a dual DAC player has now become available to everyone. Its separated channel circuit design offers less noise and interference, yet adds more fidelity and audio output power, to create a bigger sound stage with clearer imaging when paired with your favorite cans or speakers.
Higher audio output with the same refined Astell&Kern sound signature.
With a substantial power output of 4.0Vrms from the balanced output, the AK70 MKII can drive a wide range of heavy, hard-to-drive headphones without a problem thanks to Astell&Kern's latest audio design technology.
While maintaining the natural and neutral tone and sound signature Astell&Kern is famous for, the newly designed audio circuit creates authentic sounds by exceeding previous Hi-Fi Audio specifications, including SNR, Crosstalk, and THD+N, over previous models.
The powerful AK70 MKII's sound quality is sure to please even the most discerning music aficionado.
AK70 MKII delivers superb Hi-Fi audio quality in a pocket-sized portable, a must-have feature for listeners who want high quality sound any place and anytime. No need to compromise with lossy, compressed music anymore.
The ergonomic body design fits nicely in the palm of the hand, making operation a smooth, one-handed experience.
24-bit, 192 kHz Bit-to-Bit 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.
The AK70 MKII delivers original sound using the 2.5mm 4-pole balanced output that Astell&Kern first pioneered on the AK240 (and other manufacturers soon adopted). The balanced out provides a more powerful audio signal with less noise interference.
A simple USB connection will allow the AK70 MKII to be used as a digital music storage device and/or pre-amp to output digital audio through USB.
The AK70 MKII transfers DSD in native format through DoP (DSD over PCM) and converts DSD to PCM for output
for external USB Audio that do not support DoP.
* USB audio (Digital Out) output is available only when an external device can accept digital input through USB.
* DoP (DSD over PCM): This is the standard for transferring DSD data to a USB interface and sends DSD data by mounting them onto PCM data frames.
* The type of OTG cable to connect the AK70 MKII with a portable amp differs depending on the specs of the amp. An OTG cable is not included in the AK70 MKII package.
Connect to your PC/Mac computer, or other system, 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 favorite streaming service!
When using the AK70 MKII as a USB DAC, playback up to 24-bit, 96kHz is supported to deliver a much richer sound through a larger soundstage and resolution that goes far beyond the limits of an embedded sound card.
Want to easily play back DSD on your computer? No problem. Using the PC's embedded sound card usually requires a complicated process to playback DSD data, but with the AK70 MKII, simply install our DAC driver on your PC/MAC and play DSD with ease.
* AK70 MKII supports up to 24-bit 96 kHz with USB audio class 1.0 specs.
* DSD 64/128 is converted via DSD-to-PCM for playback.
AK Connect, a DLNA-based music control app, is available on the AK70 MK2 and smart devices including your phone or tablet.
