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.
