About the SH
The Unison Research SH is a Class A, single-ended headphone amplifier utilizing a simple two-stage tube circuit with a passive volume control. It employs EL84 tubes in triode mode for the output stage and ECC83/12AX7 tubes for the input stage, delivering distortion typically below 0.15%. The amplifier includes a high-quality internal USB DAC based on the latest generation ESS Sabre DAC with jitter elimination, supporting PCM up to 384kHz and DSD up to 128x. It offers two parallel headphone outputs, one RCA line input, and one USB input. The design emphasizes sonic purity and linearity with a feedback factor of 16 dB and a damping factor of 3 on 20 ohm load. Dimensions are 22.5 cm x 12.6 cm x 32.2 cm, weighing 6 kg, with a power consumption of 45 W. The SH is noted for combining classic valve refinement with modern digital technology to produce a stunning sonic performance.
