Astell&Kern PPM42 includes MQA technology, which enables you to
play back MQA audio files and streams, delivering the sound of the
original master recording.
The PPM42 Now Playing status shows green or blue light to indicate
that the unit is decoding and playing an MQA stream or file, and
denotes provenance to ensure that the sound is identical to that of
the source material. It glows blue to indicate it is playing an MQA
Studio file, which has either been approved in the studio by the
artist/producer or has been verified by the copyright owner.
