Unison Research TRIODE 25 Black Edition Valve Amplifier
Unison Research TRIODE 25 Black Edition Valve 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.
The new Triode amplifier 25 has experienced a long and painstaking design and testing period despite the considerable experience already gained in the construction of its predecessor, the Triode 20. The Triode 25 can operate in two modes: triode and pentode. The latter is capable of delivering a maximum power output of over 45 watts per channel with a load of 6 ohms with harmonic distortion extremely contained across the entire audio band.
To improve the Triode 25 at our special launch of the BLACK EDITION we worked on its strengths and we went even further to achieve higher sound quality.
The circuitry has been revised in the signal path and power management, again surpassing the milestones already achieved in the Triode 25. We reduced the distortion and increased the power.
Thanks to its specially designed circuit the power valves of Triode 25 Black Edition can operate either in triode or pentode mode.
The input selection circuit now utilizes the same advanced technology found in our most premium equipment. We’ve also paid extreme attention to the design of ground paths and channel separation to ensure optimal performance.
The valuable audio signal, where possible, travels protected in high-quality coaxial cables.
All the new Black Edition series are equipped with 3 digital inputs USB,SPDIF and Toslink
