SMSL SU-1 MQA Audio Decoder for Hi-Res Listening

The SMSL SU-1 is a compact and high-performance digital-to-analog converter (DAC) that supports the latest MQA (Master Quality Authenticated) technology. Measuring just 96mm x 78mm x 27mm, this aluminum alloy CNC-machined device boasts an ultra-miniature design while delivering exceptional audio quality.

The SU-1 utilizes the cutting-edge AKM AK4493S DAC chip, which achieves a remarkably low distortion level of less than 0.00013% (-117dB). This state-of-the-art component, combined with the device's meticulous engineering and attention to detail, ensures an exceptional listening experience.

Regarding connectivity, the SU-1 offers a versatile range of input options, including USB, optical, and coaxial connections. The USB input is compatible with a wide range of operating systems, including Windows 7/8/8.1/10/11 (with driver), Mac OS X 10.6 and above, Linux (driverless), Android, and iOS. This broad compatibility ensures seamless integration with your digital audio sources.

The SU-1's output level is a robust 2.0Vrms, providing ample power to drive a wide range of audio equipment. The device boasts an impressive dynamic range of 121dB and a signal-to-noise ratio (SNR) of 121dB, ensuring a pristine and immersive audio experience.

The SU-1's support for MQA (Master Quality Authenticated) technology is a standout feature. MQA is a revolutionary audio codec that can "unfold" and restore the original high-resolution signal heard in the studio, providing listeners with a more authentic and engaging listening experience. This technology is particularly beneficial when used with MQA-encoded CDs, as the SU-1 can authenticate and decode the MQA signal, delivering the original high-resolution audio.

In terms of supported audio formats, the SU-1 can handle a wide range of bit depths and sampling rates. For USB input, it supports 1-bit to 32-bit PCM audio at sampling rates from 44.1kHz to 768kHz, as well as DSD formats from 2.8224MHz to 22.5792MHz. For optical and coaxial inputs, the supported bit depth ranges from 6-bit to 24-bit, with sampling rates up to 192kHz.

The SU-1's power consumption is remarkably low, with less than 5W during operation and less than 0.1W in standby mode. This makes it an energy-efficient choice for your audio setup.

In summary, the SMSL SU-1 is a compact and feature-rich DAC that leverages the latest MQA technology and the high-performance AKM AK4493S DAC chip to deliver exceptional audio quality. Its versatile connectivity options, support for a wide range of digital audio formats, and energy-efficient design make it an attractive choice for audiophiles and music enthusiasts alike.
