The Douk Audio U2 PRO is a USB digital interface — a bridge that takes audio from a computer over USB and hands it to your DAC through the DAC's digital inputs. It's a specialist piece of kit for people connecting gear that doesn't speak USB directly, or who prefer feeding their DAC through a dedicated digital output stage.

It suits hi-fi hobbyists with an existing DAC that lacks USB input, or system builders who want to separate the USB conversion step from the DAC itself. At under $85, it's an inexpensive fix for a specific problem in a digital chain.
