Unison Research Triode 25 black edition
To improve the Triode 25 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
