The Unico 90 is a near-perfect integrated amplifier, employing as few active amplification stages as possible to produce a clean musical signal that is true to the original source material. Where the more powerful flagship, Unico 150 had three active stages, the Unico 90 boasts lower power specifications but only uses a two-stage circuit with zero global feedback.

The Unico 90 is an integrated amplifier designed to accommodate a variety of sources via its three RCA and two XLR pair inputs. It’s also designed to work in almost any application, with its fixed and variable RCA outputs as well as the bi-wirable speaker terminals. The large casework is built to the same exacting standards as previous Unico designs, but the Unico 90 borrows the same three-plate front fascia introduced with the Unico 150, which adds an aesthetic enhancement over its predecessors. Operation is simple and effortless via the large front-panel controls or the supplied RC2 system remote; but the minimalist exterior belies the high-end technology hidden within.

Internally the Unico 90 employs lots of clever technology, including only two active stages, sophisticated valve configurations, premium components and dual-mono circuitry. The extensive R&D that went into designing the Unico 90 has resulted in a product with unrivalled cosmetic, scientific and musical appeal.

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.
