Our audio upgrade kits offer a selection of the best quality modern production items along with high quality new old stock valves to give you an improved sound and a cost effective upgrade. We have over 30 years' experience with using and listening to high end audio amplifiers and over 25 years in improving the valves. These kits have been put together after many hours of listening tests to confirm the valves performance in any given application.

Unison Research was founded in 1987 by a group of passionate audiophiles led by Giovanni Maria Sacchetti. These amplifiers have taken electronics and craftmanship to a new level. My first encounter with these amplifier was the remarkable Simply Four amplifier. This amplifier gave international success and established Unison Research.

Our revalve kits are born out customer feedback from years of suppling valves for these beautifully designed and made amplifiers
