The TOPPING HS01 is designed to eliminate ground loop noise and improve audio quality by electrically isolating a DAC from its connected computer. This device effectively mitigates hum in audio systems by reducing ground loop noise by up to 50dB in real-world applications. It supports high-speed USB 2.0 transmission, compatible with high-resolution audio formats including PCM up to 32bit/768kHz and DSD512 Native. Unlike many USB devices that experience latency between 5 to 20 milliseconds, the HS01 boasts an extremely low latency of only 0.29 microseconds, making it suitable for audiophile needs. The compact dimensions of the HS01 are 0.9 x 2 x 0.35 inches (2.3 x 5.3 x 0.9 cm). Included in the package are the TOPPING HS01, a USB cable, a user manual, and a warranty card.
