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 Research 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

"Tonally fun...Great spatial separation...the soundstage has depth and layering to it that's usually reserved for much more expensive components."
