A perfect example of Italian style and design, the innovations contained in the Unico integrated amplifier designs are universally appreciated and recognized.

The Primo is a stereo integrated amplifier that offers elegant lines and details, thanks to carefully considered surface finishes and proportions. Solid construction, careful selection of components and precise assembly are part of an almost artisan approach to amplifier design, reflecting our origins in Treviso. Unison Reasearch has concentrated all of our experience, knowledge and ambition into a small amplifier—one that includes all the technology and passion that one usually finds in the finest flagship products.

Many years have passed since Unison Research started a small revolution in the world of hi-fi, presenting the market with its masterpiece—the Act integrated amplifier. Unison Research has since continued to run tests and experiments with the spirit of a technician in love with music, aspiring to find those hidden laws and secret that transform an amplifier into a magic box that can liberate music and give it vitality. We developed many new ideas so that the secret formula for a good amplifier could be completed, resulting in a new version of one of our most famous and beloved products.

The Unison Research Unico Nuovo remains firmly at the vanguard of integrated amplifier design, offering audio performance at the highest level with pleasing aesthetics at an affordable price.

The Unico 150 amplifier has been designed to suit both high-end audiophile and highly scientific criteria. This dual-approach to development has led to the creation of a product that is different to anything Unison Research – or any other manufacturer – have developed before: a powerful, great-sounding amplifier with only three stages (two tube stages and one power MOSFET stage).

Unico 90 is a class AB hybrid integrated amplifier with zero feedback, as the most precious valve amplifiers uses only two stages. The heart of the Unico 90 circuit is found in its hybrid structure. All of the gain, and subsequently the “character” of the amp, is determined by the only tube stage made with ECC83 and ECC 81in particular multiple-parallel-totem-pole.
