Unison Research Unico Nuovo Integrated Amplifier

Now Including Phono Card (Factory Installed), a $120 value!

The Unico Nuovo builds on the heritage of the original Unico series, elevating Unison Research’s celebrated hybrid topology to new heights. Like the Unico Primo and earlier Unico P, the Nuovo is based on a single triode stage per channel, but it carves out its own place in the lineup through a series of significant design innovations.

Enhanced Tube Front-End for Greater Musical Refinement

At the heart of the Unico Nuovo is a pair of ECC83 (12AX7) valves, implemented in a parallel double-triode configuration. By doubling the number of triodes compared to the Unico Primo, and by applying a new biasing approach, the Nuovo achieves:

• More refined harmonic texture

• Improved micro-detail

• Greater dynamic nuance

• A smoother, more liquid midrange

This expanded triode architecture brings listeners closer to the emotional core of their music, while still offering the control and punch Unico hybrids are known for.

Innovative “Ionic Bias” System for Long-Term Performance

The Nuovo introduces a new ionic biasing solution, originally derived from high-end phono stage designs. This sophisticated system works in tandem with a Unison Research–designed power supply and the amplifier’s “level shifter” and “signal follower” stages to:

• Maintain perfect bias automatically as valves warm up and age

• Deliver consistent, stable performance over time

• Reduce maintenance and extend valve life

• Ensure optimal linearity and low distortion

You get the beauty of tubes — without the fuss.

MOSFET Output Stage with Symmetrical Current Mirror Driver

In the driver section, the output devices are fed by a symmetrical current-mirror stage using bipolar transistors. This method dramatically reduces phase shift and preserves the natural, valve-inflected character of the signal.

The power stage uses symmetrically laid-out MOSFETs, both receiving energy from a specially configured power supply to maintain exact voltage delivery. The result:

• Excellent channel balance

• Higher efficiency

• Increased control over difficult speakers

• Greater clarity and space between instruments

Together, these elements create a hybrid amplifier that feels fast, expressive, and remarkably transparent.

Premium Craftsmanship & Upgraded Chassis Design

All Unico series components now feature meticulously finished sandblasted and anodized aluminum front panels. This advanced process:

• Bombards the metal with microscopic ceramic spheres for a seamless, matte surface

• Adds a protective oxide layer that increases durability and hardness

• Enhances the clean, modern aesthetic of the Unico line

The Nuovo looks as elegant as it sounds — a visual complement to any premium listening space.

Why Choose the Unico Nuovo?

• Hybrid design that blends tube warmth with solid-state control

• Enhanced valve stage for richer tone and detail

• Automatic ionic bias for reliability and longevity

• MOSFET power section for power, stability, and musicality

• Outstanding build quality from Italy’s premier valve-focused manufacturer

The Unico Nuovo is ideal for listeners seeking a refined, engaging sound that balances warmth, detail, and authority.
