Unico 90

Unison Research's Unico 90 sits at the top end of the Unico range borrowing a lot of its look and design from the flagship Unico 150 integrated amplifier. 

The Unico 90’s dual mono design gives this amplifier more power and control of your music. Boasting 160W (4Ω) per channel the Unico 90 is capable of driving some of the most demanding loudspeakers with ease and aplomb.

On the back of the Unico 90 flexibility is available in spades with a selection of inputs including two balanced XLR as well as standard RCA. There is also 4 + 4 speaker terminals allowing for bi-wiring, and a subwoofer output to add even more depth and enthralment.
