Integroitu vahvistin

Unison Research® is celebrating with a special edition of our most successful products: Simply Italy, S6 and Triode 25. The Black Edition boasts advanced technical and sonic performance, featuring a new cosmetic design with a piano black wood front panel, black gun metal finish and updated lettering graphics.

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.

The Triode 25 Black Edition amplifier is able to meet the needs of the most demanding users, featuring:

• Triode and Pentode working mode (30 W and 50 W)
• Bias adjustable
• Feedback adjustable in two positions
• Unfiltered SUB output that maintains the sound timbre of the amplifier designed to be connected to active subwoofer
