UNISON RESEARCH UNICO NUOVO PHONO

Hybrid integrated stereo amplifier. Version with built-in phono stage 

Unison Unico Nuovo is a hybrid Class A stereo integrated amplifier, produced by the Italian brand recognized as a benchmark in the Hi-Fi sector. This model combines the musicality of vacuum tubes with the precision of solid-state devices, delivering 95 Watts RMS thanks to a reinforced MOSFET output stage and a preamplifier based on the ECC83/12AX7 dual triode. The electronics, the result of decades of experience and continuous experimentation, retain the hybrid topology of the historic Unico series, refining every detail to achieve a coherent and uniform sound quality across the entire audio spectrum.

The elegant and slim chassis, available in silver or black finishes, reflects Unison Research’s artisanal philosophy: every component is carefully selected, favoring locally sourced materials from northeastern Italy, and every assembly and testing phase takes place in the Treviso laboratories. The top ventilation slots ensure efficient heat dissipation while maintaining a refined and minimalist aesthetic, perfectly aligned with the rest of the Unico range. The front panel houses two essential knobs for volume and input selection, each accompanied by a discreet LED, while the wooden remote control allows all functions to be managed with elegance and solidity.

The amplifier’s hybrid architecture leverages the musicality of tubes in the preamplification stage, providing warmth and detail in the mid and high frequencies, and the power of MOSFETs in the output stage, responsible for precision in the low frequencies and the ability to deliver energy dynamically. The power supply section, composed of an encapsulated toroidal transformer and powerful filtering capacitors, enhances dynamics and low-end response, while the auto-bias circuit of the tube stage delivers finer nuances and optimal gain control.

Unison Unico Nuovo thus represents a concentrated expression of Unison Research’s design philosophy: high-level integrated electronics engineered to offer Hi-End performance, outstanding musicality, efficiency, and accessibility. It is an amplifier that unites tradition and innovation, with a simple yet sophisticated design and artisanal care that makes it immediately recognizable and perfectly integrable into any high-quality audio system.
