Portable DAP (Digital Audio Player)

The Astell&Kern is the ultimate portable high-fidelity audio system capable of playing Mastering Quality Sound (MQS) from music mastering studios. MQS refers to all of the high resolution digital music recording studio formats up to 24-bit/ 44 – 192kHz. MQS delivers vast amounts of better music experience because MQS delivers 6.5 times of the detailed information in the same track.

Astell&Kern natively supports MQS (24-bit / 44 - 192kHz) which is the closest to the original sound that the original recording artist intended. Mastering Quality Sound (MQS) is an acronym of collective lossless & high-resolution audio source formats that typically comes encoded with 24bit, 44 to 192kHz of bit/sampling rates. Since MQS delivers about 6.5 times more detail than a conventional CD (16bit/44.1kHz), listeners can enjoy more a realistic music experience.
