About Unison Research

Unison Research, founded in Italy, has a long-standing reputation for crafting high-fidelity audio equipment that marries traditional craftsmanship with cutting-edge technology. Each product reflects their passion for music and dedication to producing equipment that delivers both sonic excellence and visual beauty. 

Refined Circuitry and Design

The Unico Due’s electronic circuitry has been completely redesigned, incorporating key improvements while maintaining the qualities that made the Unico range a legend in the audio industry. Enhancements include a significant increase in filter capacitance and a new shielded and encapsulated power transformer. The power distribution system optimizes space and circuit solutions, ensuring improved assembly and service capabilities. The heart of the preamplifier stage centers on two ECC83 double triodes, configured as a gain stage followed by a cathode-follower. This setup, selected after extensive listening tests, ensures low output impedance and efficient power stage driving.

Build Quality

The Unico Due is constructed with meticulous attention to detail, focusing on both power supply and signal management. The power output stage supply is designed to handle high-value, impulsive currents, utilizing large-value capacitor banks placed close to the power transistors. The supply tracks on the PCB are generously sized, with the ground return tracks carefully designed to ensure optimal performance. All audio signal paths feature high-quality components, including gold-plated connectors, sealed micro-relay switches, and low-tolerance metal film resistors. The result is a robust and reliable amplifier built to last.

Sonic Performance

The Unico Due is engineered to deliver a sound that is dominated by its valve section, providing a warm and engaging listening experience. The solid-state power output stages are configured with a “super symmetrical” design, reducing distortion at low listening levels and ensuring transparency across all conditions. The amplifier’s dynamic Class A biasing keeps the transistors partially active, even at low volumes, preserving sound quality and depth.

Versatility and Compatibility

The Unico Due is designed with versatility in mind, offering multiple input and output options to accommodate various audio sources and setups. It features three analog line inputs, a USB digital input, and a low-impedance subwoofer output. Additionally, one of the analog inputs can be configured as a phono input for turntable enthusiasts, making the Unico Due suitable for a wide range of audio systems.
