Pride and passion

Unison Research is the Italian leader in the production of valve amplifiers

Unison Research was founded in 1987 by a group of passionate audiophiles led by Giovanni Maria Sacchetti.

Since the first amplifiers (the now historic Triode20 and SimplyTwo) Unison Research’s high-fidelity systems have been a great international success

Under the guidance of Giovanni – able to combine electronic expertise, musical passion and taste for design – Unison Research has created amplifiers and systems that have become historic and of great value.

Unison Research is now recognized as the Italian leader in the production of tube amplifiers, and among the top ten in Europe.
