U18 asynchronous USB interface
Yulong Audio proudly introduces the U18, an audiophile asynchronous USB interface that supports up to 24bit and 192KHz playback. Through extensive testing and validation by the Yulong tuning team, U18 achieves high fidelity sound so engaging and musical that it will keep you listening. By using very low jitter clock generators, U18 eliminates the digital sound typical from CAS, and serves as the finest bridge between your PC and DAC.
Base on the TE8802L, U18 has customized driver to support Windows (XP/Vista/7) and Mac OS X. It includes AES/EBU, Toslink and Coaxial outputs to insure compatibility with your DAC, while the I2S interface would allow more choices for the DIY lovers.
U18 automatically switches between USB power and external power. When powered through USB, its strong regeneration circuitry will provide low noise power source to ensure high voice quality. Still, the more demanding users can optionally use an external linear power supply to enable galvanic isolation with the PC power, to deliver an even higher audio quality."
