Overview
The Unico 150 amplifier has been designed to suit both high-end audiophile and highly scientific criteria. This dual-approach to development has led to the creation of a product that is different to anything Unison Research – or any other manufacturer – have developed before: a powerful, great-sounding amplifier with only three stages (two tube stages and one power MOSFET stage).

Unison Research was founded in 1987 by a group of passionate audiophiles led by Giovanni Maria Sacchetti. Born in 1945, Giovanni Maria Sacchetti devoted himself at an early age to the study and design of hi-fi systems, combining his interest in electronics with a passion for music inherited from his father, an expert pianist. After completing his studies in electronics, he devoted twenty-five years to teaching while at the same time designing and developing amplifiers for Unison Research. Our experience has increased over the years, along with our continuing research of high performance and high quality standards. This has led Unison Research to both historical achievements and great value when it comes to the development of our products. Best of all, we have achieved this through a completely Italian operation…from design to production. Unison Research is now recognized as the Italian leader in the production of tube amplifiers, and among the top ten in Europe. All Unison Research products are characterized by an elegant style, and the care with which wood and metal parts are selected for each design. It’s a quality that is recognized and appreciated worldwide. We firmly believe that a system of high-fidelity music reproduction should not only be a pleasure to hear, but to see as well.
