Unison Research was founded in 1987 by a group of passionate audiophiles led by Giovanni Maria Sacchetti. After completing his studies in electronics, Giovanni devoted twenty-five years to teaching while at the same time designing and developing amplifiers for Unison Research, including the legendary SIMPLY TWO, achieving great international success in a relatively short time. Designed and produced to high performance and quality standards entirely in Italy, Unison Research is now recognised as the Italian leader in the production of tube amplifiers, and among the top ten in Europe.
