Unison Research are an Italian hifi manufacturer, specialising in valve technology and offering a performance that brings the listener as close to their music is possible. Perfectly matched with vinyl, Unison Research models deliver a warm and compelling performance.

This prestigious level of experience comes with decades of designing and engineering high-quality audio products. The Performance is an excellent example of Unison Research's skill and prowess, as a single-ended Class A integrated amplifier with a parallel internal layout. This results in a superlative level of sound staging and a truly legitimate valve experience.

Large, thermic radiators can be found on either side of the unit, while two stainless steel screens act as a cover. This cover is amagnetic, with low heat conduction meaning that the heat generated by the six high-quality KT-88 valves do not reach the circuitry below, meaning that both the integrity of the sound and that of the durability of the product remain intact.

The Performance uses a dual mono configuration in its layout. This means that inside the chassis of the unit are two identical amplifiers, running completely independently from each other. This in turns results in a drastic reduction of the possibility of interference between the two channels. 

An array of outputs and inputs can be found on the rear panel, including speaker terminals capable of 4 and 8 ohm loads. A power output is also present, designed for the Simply Phono. Tape Out/In connections are also present.
