Unison Research Unico Pre Hybrid Stereo Preamplifier

The Unison Research Unico Pre is a hybrid stereo preamplifier available at Vinyl Sound USA Inc. in Buffalo, NY, your authorised Unison Research dealer serving Western New York and the United States. Born from intensive engineering research at Unison Research's Treviso, Italy workshop, the Unico Pre combines a tube-driven Class A triode input stage using two ECC82 (12AU7) valves with a solid-state BJT output stage, delivering the harmonic warmth Unison Research is known for alongside the drive, control, and system flexibility of a fully engineered hybrid topology.

Built into the same two-element front panel architecture shared across the top-tier Unico line, the Unico Pre is designed to sit at the heart of a high-end two-channel system, whether paired with Unison Research's own Unico DM power amplifier or driving a third-party amplifier through its balanced XLR or single-ended RCA outputs. Connectivity is comprehensive for a component in this class: four line-level inputs (RCA and XLR), a dedicated tape input, a tape output, and a subwoofer output, all controlled from the included IR remote for volume and source selection. A flat frequency response from 10Hz to beyond 100kHz, 0dB negative feedback, and a 95dB signal-to-noise ratio keep the signal path clean while the tube stage adds the natural, engaging character Unison Research amplifiers are built around.

For listeners assembling or upgrading a preamp-plus-power-amp system, the Unico Pre offers a way into genuine Italian tube-hybrid design without stepping up to Unison Research's flagship Reference-series separates. Visit Vinyl Sound Buffalo to audition the Unico Pre alongside the rest of the Unison Research lineup, from the Unico integrated amplifiers to the Reference Pre and Reference monoblock power amplifiers.
