JDS Labs OL DAC USB and Optical Edition

JDS Labs decided to set the highest bar with OL DAC, by far outperforming ODAC and eclipsing the sea of alternatives beyond just benchmarks. OL DAC's external AC power supply ensures 100% consistent noise performance, relay muting eliminates power-up transients, and it's the only DAC at its price point with both USB and optical inputs.

Fantastic value.

Optical and USB Inputs
OL DAC provides the basics. Its USB Audio Class 1 engine is plug-and-play with all operating systems, and optional optical input expands connectivity to home entertainment. Mode is easily selected by a front mounted slider switch.

Differential Summing Output
The differential output of the AK4490EQ DAC is summed by a low noise amplifier, with DC coupling throughout. Directly drive any load.

Externally Powered
OL DAC is powered by the same circuitry developed for JDS Labs' flagship EL DAC, using an AC power adaptor and 9 linear regulators to ensure consistent rail voltage and super low ripple (no USB power).
