    Asynchronous USB

    With a true Asynchronous interface our Ultra Low Noise Femtosecond Master Clocks control the output jitter from the computer source. This provides the lowest noise digital source for the system DAC and unprecedented sonic transparency from any source file.

    Galvanic Isolation on Outputs

    The ULink provides galvanic isolation from the USB born noise through the transformer coupled SPDIF output or the high speed ST fiber output.
