TRIODE 25

Integrated Amplifier

Three amplifiers symbolize the success of Unison Research: the Simply Two, the Triode 20 and the legendary Absolute. On the occasion of the 25th anniversary of the birth of Unison Research, we pay homage to these historic devices by offering the Simply Two and the Absolute in a limited and numbered “Anniversary” edition. We’ve also decided to offer a completely new version of the Triode 20 and named it, quite appropriately, the Triode 25.
