Unison Research


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 those 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, the company believed they could eliminate the problems so often associated with poorer quality 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. 

Over 25 years on, and Mr. Sacchetti is still involved in the core design and overall direction of Unison Research, but the introduction of new specialists and a close working relationship with the University of Padua has also seen the brand develop to include the class-leading Unico hybrid series. The introduction of the Unico range has also allowed Unison Research to introduce a series of highly-regarded source devices, including the hugely successful Unico CD.

The current Unison Research range is represented by the Valve and Unico series, with other accessories including phono stages also available. There's something available for any system, and all products maintain the historical reputation of putting both sound design and aesthetic appeal first. All internal components and almost all the external parts are locally sourced, while all R&D and assembly is still conducted in house; ensuring each item purchased has been hand-assembled and tested by an expert engineer with an intimate knowledge of good sound.

Pride In Design

From their first days, Unison Research's aim has always been to convey pleasure by listening to music. That's why, due to the realism they can offer, the company has always focused on either pure-valve or valve-hybrid electronics. It takes real passion to create products that provide the gift of timeless pleasure, and that's why the company's facility in Treviso Italy has a small family feel to it.

All Unison Research products are characterized by an elegant style, and the care with which wood and metal parts are selected from respected local suppliers (wherever possible) shines through in each finished product. It's a quality that is recognized and appreciated worldwide, and wouldn't be possible without the intimate knowledge the specialised production team has accumulated over the years.
