Unison Research S6 Black Edition

The Unison Research S6 Black Edition is designed to deliver pure acoustic fidelity through scientific principles of sound reproduction. Its advanced engineering ensures that the listener experiences audio without coloration or distortion, providing true-to-source playback.

---

The engineering of the Unison Research S6 Black Edition amplifier focuses on eliminating feedback and utilizing advanced polarization methods to enhance signal integrity. The amplifier operates in Class A with six KT77 output valves configured in parallel, driving the system with a power output of 40W. This configuration, combined with carefully selected Gold Lion valves and a bespoke output transformer, facilitates a broad frequency response extending from 15Hz to 30kHz, allowing for reproduction of low harmonics crucial to a realistic sound stage. The meticulous design includes an enhanced input circuit with micro relays that minimize noise and maximize channel separation, ensuring that the audio signal remains pristine throughout its path. Furthermore, the removal of electrolytic capacitors at the cathodes of the power valves maintains clarity and precision across the frequency spectrum, ultimately delivering an acoustic experience that prioritizes authenticity.

Key Features

• Dual Mono Amplification: Achieves independent power management for each channel, enhancing stereo separation and reducing distortion.
• Cathode Capacitor Less Technology: Eliminates phase shifting and low-frequency coloration, resulting in a more accurate reproduction of the audio signal.
• Unfiltered Sub Output: Maintains the timbre of the amplifier for low-frequency reproduction without unwanted filtering artifacts.
• Micro Relay Input Selection: Uses advanced relays for selecting inputs, significantly reducing crosstalk and noise between channels.
• High-Quality Coaxial Cables: Protects valuable audio signals, preserving integrity during transmission and minimizing interference.
• Enhanced Power Supply: Utilizes strategically placed polypropylene capacitors for improved transient response and dynamics, facilitating a cleaner signal path.
