Unison Research Simply 845 single ended valve amplifier

Unison Research is a italian manufacturer, with an extensive catalog ranging from amplifiers to loudspeakers, all of which are top-notch and highly regarded worldwide. Numerous are the tube products, in which the manufacturer has always been able to distinguish itself. The amplifier under test, a novelty in the catalog, is characterized by the use of a single 845, which is extremely high-performance and capable of delivering, by itself, a fair amount of output power. The sound that characterizes it is fascinating and enveloping, and has always won over without appeal any audiophile who has come in contact with it. Simply 845 is a mature product, impeccably constructed and manufactured and with many original circuit solutions, not the usual copy-paste of already known schemes in short. The price is the mathematical consequence of all these considerations, and should be evaluated considering many factors, including the hand-polished real solid wood finish.
