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 SU-9 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

• The SU-9 supports MQA decoding on the USB interface.
• SU-9’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.
• The SU-9 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.The SU-9 LED next to MQA logo glows magenta to indicate that the unit is rendering an MQA stream or file. This delivers the final unfold of the MQA file.
• When playing an MQA file, the sampling rate of the original master recording is displayed.

Instructions

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

• 47kHz Cutoff
• 50kHz Cutoff
• 60kHz Cutoff
• 70kHz Cutoff

SOUND COLOR
There are 9 sound color settings in SU-9.

• Rich1、 Rich2、 Rich3
• Tube1、 Tube2、 Tube3
• Crystal1、 Crystal2、 Crystal3

This setting is usingthe DSP of ES9038PRO,to make some different sound color, all of these settings will not change the frequency res ponse curve.When set to “Standard”, this setting will be bypassed.

PRE MODE
Volume control enable or disable.

• V ol Fixed : In this mode, volume is fixed on max output level, and the SU-9 will ignore the volume operations.
• Vol Variable: In this mode, volume can be adjust by remote controller, and make SU-9 a pre-amplifier.

DPLL

MIN ~ MAX
(A total of 15 kinds, the default is 7 kinds. The larger the number is, the stronger the range to adapt to jitter, and the smaller the number, the better the performance against clock jitter.)

BRIGHTNESS

• LEVEL 1 ~ LEVEL 6
