We reviewed your comments and we listened to your requirements to redesign this product. We now take it one step further by improving all key aspects of the base concept.

The brand new XU2S USB Digital Audio Interface is shipping now!

Upgrading your DAC to the highest level with this no-compromise interface will further refine your listening experience!

USB audio playback interface - revisited

The XU2S USB Digital Audio Interface is an easy-to-integrate OEM solution for high-end USB audio playback systems, supporting USB Audio Class 2.0.

USB streaming is based on an asynchronous protocol, clocked by ultra-low jitter on-board oscillators. Using this concept, the design benefits of a local high quality master clock to achieve highest quality, jitter-free digital audio playback. Electronic parts have been carefully selected for the best performances. The oscillators have been developed in collaboration with a Swiss clocking devices manufacturer. All local voltage regulators are very low noise. AES/EBU and S/PDIF transformers are best in class. Full galvanic isolation avoids any interference issues between the audio device and the USB host. Critical components are powered by an external source to ensure optimal performances. The interface can also be configured to work with bus power only, convenient for using the board as a simple USB to S/PDIF mobile interface. Additionally, connections on USB side are protected against short transient electrostatic discharges.
