Reclock the digital signal from your computer and connect to your DAC
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.

Computer Audiophile, April 2013
"Computer audiophiles seeking great performance without financial hardship should include the uLink on a small list of great converters with unique features, great design, and great sound quality. I highly recommend the Bel Canto uLink USB to S/PDIF converter and award it a place on the [Computer Audiophile Suggested Hardware] List without hesitation."
Sound Stage! HiFi, Sathyan Sundaram, March 2014
"For those with DACs lacking USB inputs, the uLink provides an easy and musical way of adding computer-based audio to a system. More important, as an asynchronous USB converter, it improves performance at the lower and more common sample rates of 44.1, 48, 88.2, and 96kHz in clearly audible ways, reducing noise and thus increasing clarity. It’s perhaps surprising that sending signals through an additional step and an additional box full of circuitry can provide superior sound..."
