About MQA

MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. The D1se includes MQA technology, which enables you to playback MQA audio files and streams, delivering the sound of the original master recording.
Visit How it works https://www.mqa.co.uk/how-it-works for more information.

MQA files playback

1. The D1se supports MQA decoding on the USB interface.
2. D1se’s MQA playback does not require additional software. You can use foobar2000 or Audirvana for MQA playback as it supports ASIO or WASAPI audio output. When playing MQA audio, it is suggested to adjust the volume of the computer to the maximum for the best audio output.
3. The D1se LED next to MQA logo 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.
4. When playing an MQA file, the sampling rate of the original master recording is displayed.

DSD FILTER

There are 4 kinds of digital filtering in total. It’s the way that the digital operation means the clutter outside the audio Filter out, respectively

1. 47kHz Cutoff
2. 50kHz Cutoff
3. 60kHz Cutoff
4. 70kHz Cutoff

SOUND COLOR

There are 9 sound color settings in D1se.
