What customers say
The Singxer SU6 Digital to Digital Converter earns high praise for delivering transformative sound quality improvements in high fidelity systems. Users consistently note enhanced clarity, superior detail retrieval, and a wider, deeper soundstage compared to standard USB outputs. This stellar performance is often attributed to its precise clock implementation, resulting in a more natural and dynamic sound signature. While initial Windows driver setup may present minor hurdles, these are quickly forgotten due to the sonic benefits. The core sentiment centers on exceptional value; many reviewers feel the SU6 rivals or surpasses much more expensive devices, making it a highly recommended, cost-effective upgrade for serious listeners seeking to maximize their external DAC performance.
Know before you buy
The SU-6 acts as a high-performance bridge between your computer and your DAC. Its main job is to clean up the digital signal by drastically reducing jitter and re-clocking the data, which results in a more precise and stable audio signal for your downstream equipment.
Yes, the SU-6 features both HDMI and RJ45 ports for I2S output. This allows for a direct, high-fidelity connection to compatible DACs, supporting up to 384kHz PCM and DSD512.
Yes, you will need to install the appropriate Singxer USB drivers on your computer to ensure proper communication and support for high-resolution audio formats like DSD512.
The SU-6 is designed to take a single USB input and distribute it to multiple digital outputs simultaneously. You can use the AES/EBU, S/PDIF, and I2S outputs at the same time, making it useful if you have multiple DACs or recording devices in your setup.
These technologies work together to ensure the timing of your digital signal is incredibly accurate. By reshaping the signal and using a high-precision clock, the SU-6 minimizes timing errors, which helps your DAC convert the digital data into analog sound with greater clarity and detail.
The SU-6 comes with a power adapter included in the box. While it is designed to work well with the provided unit, it requires a 7.5V-9V DC input if you choose to experiment with aftermarket linear power supplies.
