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 hear 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.
