The Unison Unico Primo is an 80-watt Class A hybrid integrated amplifier that skillfully combines artisanal tradition with advanced technology. Its elegant and modern design retains a handcrafted character that reflects the care and passion typical of the Treviso-based company, evident in the choice of materials, meticulous assembly, and perfect proportions. Every detail reflects a construction approach that prioritizes quality and reliability, making this integrated amplifier a concentration of experience and well-established technological innovations.

The hybrid circuit design of the Unico Primo combines the warm musicality of an ECC83 valve in the input stage with the precision and power of Class A Dynamic MOSFETs in the output stage. This design choice achieves the best of both worlds: the smoothness and naturalness of valve sound, with the definition, linearity, and bass control typical of solid-state devices. The result is a musical and engaging sound, characterized by even-order harmonics that capture the listener’s attention, with fast and precise response across the full audio spectrum.

Although an entry-level model in the Unico series, the Unico Primo carries the experience and vision of the brand’s flagship products. Its 80-watt Class A output delivers broad and controlled power, capable of naturally reproducing complex passages and wide dynamic ranges. The power supply section is enhanced with an encapsulated toroidal transformer and oversized filter capacitors, improving bass response, dynamics, and signal attack.

This integrated amplifier is designed to be versatile and functional, with a low-impedance active stereo output for connecting a subwoofer and the option to convert one of the line inputs into a phono input using an optional RIAA card. The Unison Unico Primo thus represents an elegant and refined synthesis of the best of the Italian brand’s sonic philosophy, making the legendary valve musicality accessible to a wider audience without compromising precision or technological innovation.
