Unison Research S9 Integrated Valve Amplifier

Swipe To Cycle Images

The latest version of the classic Unison Research S9 integrated amplifier offers more power and a new aesthetic form, all without sacrificing its impressive tonal characteristics or its strong performance to price ratio. The result of Unison Research's extensive experience in the design and manufacture of integrated amplifiers, the S9 is the perfect symphony between these both of these elements. The output stages of the S9 are similar to its predecessor, but the functional aesthetics and the use of different tubes take the S9 to a new level of performance.
