USB supports MQA
MQA working principle

1) Clean up the recording

When the analog sound is converted to a digital signal,time blurring will occur, blurring transient signals over time. As a result, our ears cannot tell where a single sound comes from, the comparison between recorded music and "live performances" is unremarkable!. MQA can eliminate this distortion and create a true 3D sound field, which is different from any sound you have ever heard.

Before using MQA: Common digital audio filters will damage the time resolution, There will be a "hum" before and after the transient.

After using MQA: Compared with 24\192 recording, MQA reduces the number of vibrations before and after by more than 10 times.

2) Encapsulate the sound

Once the blur in the recording Is removed, MQA will use what we call a "musical origamiMprocess, Cleverly makes this large resolution file easy to manage and can compatible with any service or playback device.

MQA Decoder: This will expand the MQA file once to provide better sound quality than CO quality, Products with MQA decoder hdsshrimp and music streaming service providers and Roon other media player.

MQA Renderer: Use the product with MQA renderer to complete the final deployment. Renderer including USB DACS and some head- phones and other portable products.For example, SU*85 can connect to the MQA Core signal and complete the expansion of the MQA file.

MQA Full Audio DAC: Products with MQA full decoder can fully expand the file to provide the best sound quality. Playing at this level, you will hear the original sound created by the artist in the recording studio, with precise files and specific DAC compensation and management.
