S.M.S.L SU-9 Ultre AK4191+AK4499EX MQA High-Performance DAC SU9U Decoder

• 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 asingle sound comes from, the comparison between recorded music and “live performances”is unremarkable! MQA can eliminate this distortion and createa true 3D sound field, which is different from any sound you have ever heard.
• Encapsulate the sound. Once the blur in the recording ls 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.
• CD Player + MQA-Enabled DAC. Your CD player's digital output (optical or coaxial) can be fed to an MQA decoder. The MQA decoder can restore the original high-resolution signal heardin the studio and confirm it, using the authentication signature. SMSLSU-9 ULTRA support MQA CD.
