The Astell&Kern MQS Portable System, the ultimate portable Hi-Fi music player

The Astell&Kern is the ultimate portable high-fidelity audio system capable of studio Mastering Quality Sound (MQS). Feel the phenomenal realism of music though 24bit/192kHz high-resolution, lossless Mastering Quality Sound (MQS) that cannot be heard through CD standards. When compared to CDs, the music files used during the mastering process in studios (24bit/192kHz) contains 6.5 times more information and results in a more original, precise and enhanced sound.


  • Meets 100% of Hi-Fi audio specifications
  • Equipped with the world’s first portable Wolfson WM8740 24bit, 192kHz high-performance DAC
  • Can be used as an external optical DAC
  • Touch equalizer (EQ) easily manipulated by the fingertips
  • A user interface with an analog feel

What is MQS? 24bit, 192kHz high-definition sound is considered as studio quality. This is also referred to as Mastering Quality Sound (MQS).
The Astell&Kern natively supports MQS (24bit, 96kHz-192kHz) and is considered as the digital music format with the most amount of information. MQS (Mastering Quality Sound) can be downloaded from GROOVERS, HighRes Audio, HDTracks and other high-definition audio file download sources.

The MQS Portable System is a portable sound system that does not need to encode MQS files for playback.
With MQS (Mastering Quality Sound), the difference can be heard and felt because the sound is distortion free and there is no data loss within the 24bit source when compared to MP3s and CDs (WAV). MQS music and sounds are commonly saved as a lossless 24bit WAV or FLAC files during record production at the time of the mastering source. The Astell&Kern is a MQS Portable System that does not need external MQS encoding, which results in a more refined and pure sound.
24bit 192kHz is the standard specification during sound mastering music production in the studio. After the mastering process, sound sources in CDs are downgraded to 16bit/44.1kHz and MP3s are downsampled to 320kbps – 128kbps. Original sound sources can be lost or distorted during downsampling.

One of the world’s highest performing 24bit/192kHz stereo DAC
The Astell&Kern is the world’s first portable device equipped with the Wolfson WM8740 DAC. Users familiar with LINN, ARCAM, and other high-end audio equipment (AV Receivers) actually have been listening to the Wolfson WM8740 high-performance 24bit/192kHz Stereo DAC at home.
With one of the world’s highest level of signal-to-noise ratio (SNR) and the lowest level of the total harmonic distortion (THD) performance, the WM8740 has the reputation of producing the richest and warmest sounds. And with the integrated WM8740 DAC, the signal to noise ratio of 113 found in the Astell&Kern AK120 significantly improves sound quality.

4 generations of MQS Albums supported on Micro SD cards
The additional memory card slot holds an important point. 24bit album recordings will soon be released with music files stored in Micro SD memory cards. For a mainstream album, LP (vinyl) records would be considered as first generation, second generations are cassette tapes, and Compact Discs (CDs) is the third and current generation. Fourth generation albums are considered as MQS albums that are released in high capacity Micro SD memory cards. Comfortably enjoy two albums at once through the dual memory card slots of the Astell&Kern. The Astell&Kern supports MQS high-resolution music stored on Micro SD cards. >
