Unison Research Unico 90 Integrated Amplifier

The hybrid design combines a pure Class A tube input stage with a Class AB Hexfet output stage. This gives you the warm, organic texture associated with tubes while maintaining the power, efficiency, and control of solid-state amplification.

By eliminating global feedback, the amplifier avoids the phase shifts and timing errors often introduced by feedback loops. This results in a more natural, open soundstage and improved transient response, making the music feel more immediate and less processed.

The Unico 90 delivers 100 watts per channel into 8 ohms and 160 watts into 4 ohms. This is sufficient to drive most high-quality bookshelf and floorstanding speakers comfortably, even those with more demanding impedance loads.

Yes, the Unico 90 features six line inputs in total, including both balanced (XLR) and unbalanced (RCA) options. This allows for flexible integration with a wide variety of high-end audio components.

Yes, the unit is equipped with binding posts that support 4+4 bi-wiring. This allows you to use separate cables for the high and low-frequency drivers, which can help improve clarity and separation in your speaker system.

The unit measures 43.5 cm wide, 44 cm deep, and 18 cm high, and it weighs 20 kg. Because it is a powerful amplifier, ensure your shelf is sturdy enough to support the weight and provides adequate ventilation for the internal components.
