Unison Research Unico Nuovo Integrated Amplifier

Unison Research Unico Nuovo Integrated Amplifier, like the Unico Primo, is based on a 'single triode stage per-channel' design distinguished through the use of dual ECC83 (12AX7) valves with a new biasing solution and a parallel double-triode design. By doubling the number of triodes and employing a parallel configuration, the Unico Nuovo acheives a more refined sonic performance than its predecessors.

Biasing Solution

The new biasing solution - based upon a design previously found in high-end phono stages, called "ionic bias" - involves the Unison Research-designed power supply working in tandem with the "level shifter and signal follower" stages that come after the triode stage to deliver an accurate, audiophile sound from this hybrid amplifier. This innovative layout allows for non-manual adjusting of the bias as the valves bed-in and age, to ensure a longer and more reliable performance.

Bipolar Transistors

In the driver stages, the output devices are fed by a symmetrical current mirror stage, made with bipolar transistors. This method allows for minimal phase displacement and a more valve-influenced sound delivery. The output devices themselves are Power MOSFETs laid-out symmetrically, and both receive power from the same power supply stage with a special configuration to ensure the required voltage is always delivered. In total, this design allows for greater channel separation and balance, higher efficiency and greater musical detail.

MM/MC Phono Stage

The Unico Nuovo is supplied in the UK with a built-in MM/MC phono stage for simple connection to a turntable. The back panel is also equipped with a low impedance stereo output for connecting to a powered subwoofer (or any other Line level input). The supplied RC2 remote control adds convenience when controlling from your listening position.

Front Panels

The aluminium front panels on all Unico series products are clean and stylish thanks to a new sandblasting and anodising process. The sandblasting consists of hammering the aluminium plate with microscopic ceramic balls at room temperature to give the surface a homogeneous and opaque finish. The anodizing process facilitates the growth of a thin film of aluminium oxide on the surface, which enhances the mechanical resistance and hardness of the surface. The end result is truly stunning to help round off this prestigious piece of equipment.

Design Principle

Many years have passed since Unison Research started a small revolution in the world of hi-fi, presenting the market with its masterpiece—the Act integrated amplifier. Unison Research has since continued to run tests and experiments with the spirit of a technician in love with music, aspiring to find those hidden laws and secret that transform an amplifier into a magic box that can liberate music and give it vitality. The Unison Research Unico Nuovo remains firmly at the vanguard of integrated amplifier design, offering audio performance at the highest level with pleasing aesthetics at an affordable price.
