Unison Research S6 Black Edition Valve Amplifier

To improve the Black Edition over the original and well respected S6; we worked on its strengths and we went even further to achieve higher sound quality.

Experience the S6 Black Edition in store with us at Yorkshire AV HQ.

The S6 Black Edition amplifier is able to meet the needs of the most demanding users, thanks to the following improvements:

• The circuitry has been revised in the signal path and power management, again surpassing the milestones already achieved in the S6.
• Power output is now 40W, 15% more than the standard model.
• The polarisation of the power output valves has been completely revised to eliminate the capacitor and cathode resistor.
• The input selection circuit has been implemented using the same technology designed for our most valuable equipment and extreme care has been taken in the design of the ground paths and channel separation.
• 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.
