The blue AK100II Portable High Definition Sound System from Astell & Kern is a pocket-sized audio system capable of studio Mastering Quality Sound (MQS) support and playback. MQS is a high definition digital music format operating at 24 bits and sample rates from 96 to 192 kHz, which translates to distortion-free sound without data loss. MQS sources are commonly saved as a lossless 24-bit WAV or FLAC files during record production at the time of the mastering source. The AK100II also supports 5.6 MHz DSD playback by converting/downsampling to 176 kHz PCM.

The AK100II has an integrated single-channel Cirrus Logic CS4398 DAC and balanced output to provide exceptional sonic quality and detail. It can also be used as an external DAC when connected to a Mac or PC via USB. The player features 64GB of internal flash memory and a microSD card slot that supports up to 128GB from a separately sold card. This allows you to store a maximum of 192GB of high definition lossless music.

The 3.3" AMOLED touchscreen provides smartphone-style control over playback, while the brushed aluminum body and volume wheel provide a smooth analog feel. The built-in battery recharges via USB and lasts for up to 12 hours of playback. The AK110II ships with a protective case and micro-USB cable.
