Unison Research Unico 150 Integrated Amplifier

The Unico 150 from Unison Research builds upon the prestigious Italian manufacturer's Unico 100 model, a well-established integrated amplifier. Designed and engineered to the specific high standards of sonic performance and build quality set out by Unison Research engineers, the Unico 150 sits at the mantle of high-quality amplification on the market today. 

Utilising a dual mono design, the Unico 150 has enough power and control to feed even the most demanding of loudspeakers with your favourite music, leaving every punchy dynamic and fine nuance completely intact and sounding as the artist and producer intended. The Unico 150 boasts a huge 220W of power, per channel into 4 ohms. 

A vast selection of sources is catered for, thanks to the Unico 150's extensive range of inputs, including two balanced XLR as well as RCA connections. 4 + 4 speaker terminals allow for high-quality bi-wiring and subwoofer outputs allow you to integrate more depth and lucidity to your system if you should so wish. The input stage uses high-quality ECC83 (12AX7) valves within its circuitry, just one element that allows this high-quality amplifier to sit as one of the most capable valve amps on the market and a true testament to the warm, rich Italian sound that Unison Research has become world-renowned for being able to offer.
