Unison Research Valve Series

Unison Research was founded in 1987 by a small group of audiophile enthusiasts led by Giovanni Maria Sacchetti, an accomplished pianist with a deep understanding and passion for music. In these early days Unison Research produced a variety of unique amplifiers, but the constant search for improvements in sound quality led them to focus on integrated designs. Their belief was that an integrated amplifier brought not just convenience, but also the potential for better sound quality by linking the pre- and power-amplifier stages inside one device, rather than using external cables. What followed was the iconic Triode 20 and the world-renowned Simply-Two integrated amplifiers, which spear-headed a new standard in audiophile-grade valve systems.
