Products - Amplifier / Pre-amplifier - Tube Amplifier
Product Brand : Unison Research
Product Name : Reference Power Amplifiers
Product Genre : Amplifier / Pre-amplifier
Condition : NEW

Many customers, already familiar with our the current products, have expressed the desire to see a new model in the catalog: an all-tube, pure Class-A power amplifier, with a power output much higher than anything so far seen from Unison Research.
With the aim of satisfying this requirement, the Unison Research team began to evaluate the possibility of producing an amplifier which would incorporate the best of what we have learned from many years of experience with valve amplifiers. The idea was certainly an ambitious one: to design a single-ended amplifier with twice the output power of the most powerful product in the catalogue, and make it truly worthy of inclusion amongst models that have made the Unison famous throughout the world.
Since this demanding project was to be developed entirely by the Unison team, it was necessary to make several important decisions concerning the overall design. Our first realization was that the Reference power amplifier needed to consist of a separate monoblock pair of amplifiers.
