Unison Research Unico Primo – Hybrid Integrated Amplifier

The Unison Research Unico Primo is one of the most celebrated hybrid integrated amps in modern hi-fi. Combining a tube preamp stage with a solid-state power stage, it delivers the warmth, liquidity, and musicality of valves with the control and dynamics of MOSFET architecture.
Perfect for listeners who want the soul of tubes without the maintenance or fuss.

Rich, Musical Hybrid Sound

At the heart of the Unico Primo is a 12AX7/ECC83 valve feeding a high-current Class AB output section.
The result is unmistakably “Unison”:

• Warm, natural tonal balance

• Smooth midrange with lifelike vocals

• Excellent bass authority and grip

• Refined top-end with zero harshness

• Stable imaging and wide, holographic soundstage

Whether you listen to classic rock, jazz, or acoustic recordings, the Primo brings a sense of realism and flow that pure solid-state amps struggle to match.

Beautiful Italian Craftsmanship

Hand-assembled in Italy, the Unoico Primo features:

• Solid aluminum front panel

• Precision-machined volume control

• Clean, elegant aesthetic suitable for any modern system

• Top-tier internal components selected for longevity and sonic purity

This is an amplifier built not just to listen to—but to live with for decades.
