Astell & Kern AK70II Portable Hi-Resolution Audio Player (64GB)

The AK70 has been reborn as the AK70 MK2 through Astell&Kern's accumulated know-how. The Mk2 model incorporates a higher output stage whilst still being a pocket-sized portable audio player that is capable of playing any digital audio up to 24-bit/192 kHz, bit-for-bit, to ensure the highest audio quality as its outputs. Under the hood is a dual DAC which separates the left and right audio channels from input to output, offering less noise and interference - creating a larger sound stage with clearer imaging when listening with your favourite headphones or speakers.

Who is Astell & Kern?

Astell&Kern have only been around since 2013, but have already developed a reputation for building some of the highest quality portable media players on the market. They firmly believe that compact does not have to mean poor quality sound, and all of their players support high bit-depth, lossless formats as well as having enough power to drive demanding headphones. This philosophy of quality also extends to construction, and the company are famous for creating products that are built to last.
