  • Unison Research’s unrivalled ability with Single-Ended valve designs is well known around the world. The SH is the company’s first headphone amplifier to benefit from such extensive knowledge and ability.
    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 something truly stunning.
