USB is not a great audio interface.
The possibility of ground plane noise and interference transfer is immense, and the device you've linked to is powered over USB, which is a poor starting point.
Been around the doors a couple of times and have to agree with Chris, USB would probably not be my first choice.
You really need to "fix" it before it sounds good as a digital connection, very sensitive to hash on the 5V mains line and prone to timing errors.

Most effective quick fix I remember was converting it to SPDIF at source, best sounding way to do this was using a Musical Fidelity V-Link 192 converter.

By the way You don't need USB to listen to DSD (sorry Chris ) as it can be done over PCM based connections like SPDIF, AES if the dac or software uses the DoP protocol to package DSD inside PCM.
