The Objective Line began as an opensource amp design by blogger NwAvGuy. Through years of customer feedback, we've engineered several amps and DACs along the same technical philosophy and design spirit. OL DAC is fundamentally the best value brought to the series, and stacks with Objective2 and/or OL Switcher to form a versatile listening center.
OL DAC provides the basics. Its USB Audio Class 1 engine is plug-and-play with all operating systems, and optical input expands connectivity to home entertainment. Mode is easily selected by a front mounted slider switch.
Differential output of the AK4490EQ DAC is summed by an OPA2227, with DC coupling throughout. Drive any devices you wish, satisfactorily.
OL DAC is powered by the same circuitry developed for our flagship EL DAC, using an AC power adapter and 9 linear regulators to ensure consistent rail voltage and super low ripple. Never be bothered by USB hubs or OS power management configuration again!
