CLASS A TUBE HEADPHONE AMP W/DAC


Unison Research’s unrivaled ability with Single-Ended valve designs is well known around the world. The SH is Unison’s first headphone amplifier to benefit from such extensive knowledge and engineering capability. The SH uses a Single-Ended Class A design with only two stages and a passive volume control. The classic refinement of the valves combines with modern technology found in the internal USB DAC to produce a truly stunning sonic performance.
