Unison Research Unico 150 hybrid integrated amplifier front view

Unison Research Unico Amplifiers

The Unico series is Unison Research's hybrid amplifier line, blending vacuum tube input stages with solid-state output power in every model. From the 75-watt Unico Primo integrated to the 220-watt Unico DM V2 power amplifier and fully balanced Unico Pre V2 preamplifier, the range covers integrated amplifiers, separates, and everything in between.

Each Unico uses Gold Lion tubes in a Class A input stage paired with MOSFET or bipolar output devices, delivering the harmonic richness of valves with the current delivery and speaker control of transistors. The flagship V2 separates introduce A.S.H.A. technology for seamless Class A to AB operation, while models like the Unico Due and Unico 150 add built-in DACs and phono stages for all-in-one convenience. All models are handcrafted in Dosson di Casier, Italy, by A.R.I.A. srl.
