MQA (Master Quality Authenticated)
The DMS-550 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The DMS-550 LED glows green or blue 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.
