Your Sound, Elevated

The Unison Research Unico 150 is a heavyweight hybrid masterpiece that breathes life, scale and emotion into every note — not just by playing music, but by revealing it. Imagine an amplifier that takes total control of your speakers and releases sound with both authority and elegance. With 150 watts per channel and a minimalist tube-tube-power signal path, the Unico 150 is, in the words of one reviewer, "among the very best and most versatile amplifiers I've ever had in my home."

Massive Power, Total Control

With 150 watts per channel into 8 ohms (220W into 4 ohms), the Unico 150 effortlessly drives both efficient and demanding speakers, delivering deep, taut bass and room-filling scale while staying composed and interference-free. Two tube stages (ECC83, 6H30) feed a Class AB MOSFET power amplifier, pairing inviting tonal richness with rapid, lively dynamics — no sluggishness, just a muscular presentation that's also engaging and nuanced. It reaches optimal linearity in under 10 minutes, so there's no long warm-up before the music flows.

Imaging You Can Step Into

Reviewers report spectacular spatial realism: piano and orchestral recordings conjure layers of backstage space and hall ambiance, with precise imaging that places each instrument in its own pocket of air. A minimalist three-stage signal path (tube-tube-power, local feedback only) and a dual-mono layout with independent power supplies and balanced XLR inputs deliver robust channel separation and effortless system integration. Six line inputs (3 RCA, 2 XLR, 1 bypass RCA), tape and sub outputs, and bi-wiring-capable binding posts round out a genuinely flexible, reference-grade integrated.
