Singxer
Singxer SU2 with Farad Super3
Best digital audio upgrade for discerning audiophiles.
The Singxer SU2 is a high-performance USB digital audio interface featuring the latest XMOS xCORE-200 series chip and Xilinx CPLD/FPGA for advanced digital audio processing. It boasts an ultra-low jitter clock system with Accusilicon clocks, achieving femtosecond-level jitter. The interface offers a variety of outputs including XLR AES/EBU, coaxial RCA and BNC, and HDMI I2S. It also supports an external 10MHz clock input and can function as an independent master clock. The included Farad Super3 power supply utilizes super capacitor linear regulation for improved audio performance.

Know before you buy
The Farad Super3 uses super capacitor linear regulation to provide a significantly cleaner, more stable power source than a standard power supply. This reduces electrical noise, which helps the Singxer SU2 achieve its full potential in jitter reduction and overall signal clarity.
If you are using Windows, you will need to download and install the specific drivers from the manufacturer's website. MacOS, Linux, and Android devices generally support the interface natively without additional driver installation.
The Singxer SU2 features internal switches that allow you to configure the I2S pinout for different DAC manufacturers. It is pre-configured to support popular brands like Denafrips, Holo Audio, and PS Audio, but you should verify your specific DAC's pinout requirements in the user manual.
Yes, the SU2 includes a dedicated 10MHz clock input, allowing you to connect an external master clock for even greater timing precision. Additionally, the unit can function as an independent master clock for other devices in your system via its MCLK/WCK output.
The I2S output via HDMI supports the highest resolution capabilities of the unit, handling PCM audio up to 768kHz and native DSD up to DSD1024. Other outputs like AES/EBU and coaxial are limited to 192kHz for PCM and DSD64 via DoP.
Yes, the Singxer SU2 is compatible with Android devices running version 4.2 or later, provided the device supports USB OTG functionality. You will need a compatible USB OTG adapter to connect the interface to your mobile device.
