S6 BLACK EDITION

Integrovaný zesilovač

Unison Research® is celebrating with a special edition of our most successful products: Simply Italy, Triode 25 and S6. 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 S6 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 S6. Power output is now 40 W, 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.

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

• Dual Mono amplification;
• Cathode Capacitor Less technology;
• Unfiltered Sub output that maintains the sound timbre of the amplifier designed to be connected to active subwoofer;
• Input selection circuit implemented using micro relays and Return GND technology;
• In addition to the 4 analogue inputs, inside the amplifier there's the new DAC3, which adds 3 more digital inputs; USB (PCM up to 384 kHz, DSD native up to 256x e DoP up to 128x), Tos-link e SPDIF up to 92 kHz as standard.
