The Unico Primo is a hybrid integrated stereo amplifier capable of delivering not less than 85W RMS continuous on a 8ohm load. As usual for Unison Research amplifiers, the declared power is actually lower in order to keep our promises in every condition. With real musical signals running through this amplifier, the maximum power will be even higher. Even though this is the entry level in the Unico line, it possesses many of the outstanding sonic qualities of our more ambitious amplifier models. Since this is a hybrid design that mates a powerful amplifier with an ECC83 triode, you get the best of both worlds with the Unico Primo: an amplifier that is powerful enough to drive most loudspeakers, and a sound quality that is usually associated with the finest valve designs.

The Unico Primo hybrid integrated amplifier is a beautiful component, both sonically, and visually. It combines the best of both worlds, with quiet operation, and a smooth, harmonically rich performance across the whole frequency spectrum. Regardless of source, it performed flawlessly in my system. Coupled with the CD Primo, it was a two of a perfect pair. Read More
