CES 2016: Unison Research SH Tube Headphone Amp

Colleen Cardas Imports was showing off Italian firm Unison Research's sexy and affordable SH ($1700) headphone amp and DAC. This is a single-ended, class-A tube amp using ECC83/12AX7 for the input stage, and EL84 triodes on the output. The DAC accepts digital signals on USB input only with word widths to 32 bits, and PCM up to 384kHz and DSD up to 128x using the latest generation ESS Sabre DAC.

On quick listen it sounded lovely, and the look is terrific with two options mixing Italian cherry wood and black anodized aluminum. At under $2000 this thing seems to be a really good deal. If you'd like to audition one, go to this page at Colleen Cardas Imports to find a dealer near you. "Unison Research" will be a little more than half way down the page.

Here's Marc Phillips to give you the run-down.
