Unico 150 Hybrid Integrated Amplifier

The Unico 150 amplifier has been designed to suit both high-end audiophile and highly scientific criteria. This dual-approach to development has led to the creation of a product that is different to anything Unison Research – or any other manufacturer – have developed before: a powerful, great-sounding amplifier with only three stages (two tube stages and one power MOSFET stage).

Unico 90 Hybrid Integrated Amplifier

Unico 90 is a class AB hybrid integrated amplifier with zero feedback, as the most precious valve amplifiers uses only two stages. The heart of the Unico 90 circuit is found in its hybrid structure. All of the gain, and subsequently the “character” of the amp, is determined by the only tube stage made with ECC83 and ECC 81in particular multiple-parallel-totem-pole.

Unico 90 integrated Amplifier Specifications

Output power: 100+100 W RMS su 8Ω / 160+160 W RMS su 4Ω

Frequency response: -1dB @ 12Hz e 45kHz -3 dB

Input impedance: 21Kohm // 300pF

Input sensitivity: 860mV RMS

Input stage: Pure A class, double triode totem pole ECC83 and parallel totem pole ECC81 This single stage due to the particular circuitry is able to amplify the input signal and drive directly the power stage.

Output stage: Class AB thermostable, complementary Hexfet (3 pairs for channel)

Number of stage: 2, This amplifier due to the particular circuitry is realized by only two stages: input stage and output stage, and use only local feedback
