The Topping HS02 is a high performance USB isolator and noise filter with dual connection. As it's fully isolated, it will not allow new interference when using an additional power supply, the audio signal is perfectly isolated from any ground loops. It has dual input and output connections: USB-B and USB-C on the input side, USB-A and USB-C on the output side. A switch on each side allows you to select the desired input and output. The HS02 also supports high sampling rates up to PCM 32bit 768kHz and DSD512.
