Ground loop noise killer 

If you’re hearing hum in your audio system, the TOPPING HS01 may help. It’s designed to electrically isolate your DAC from your computer, eliminating the noise caused by the power flowing through the ground connection.

USB 2.0 high speeds

The HS01 supports high speed USB 2.0 transmission, which is compatible with high-resolution audio transmission such as PCM 32bit/768kHz and DSD512 Native.

Low latency

Unlike many USB devices, which have a latency of 5 to 20 milliseconds, the HS01 has a latency of only 0.29 microseconds, which fully meets the needs of audiophile applications.

Eliminate ground loop noise

The HS01 can reduce ground loop noise by up to 50dB in real world scenarios.
