Unison Research Triode 25 Black Edition

The Unison Research Triode 25 Black Edition integrates sophisticated engineering to deliver high fidelity sound reproduction. It transforms electrical signals into immersive audio by precisely managing the power output and signal processing.

---

The Unison Research Triode 25 Black Edition utilizes a push-pull, ultralinear configuration to optimize power efficiency while maintaining low distortion levels. By allowing output valves to operate in either triode or pentode mode, it balances warm tonal quality with substantial power output—30 W in triode mode and 50 W in pentode mode. The amplifier features a revised signal path that enhances audio fidelity through component quality and design, while its adjustable feedback control allows users to tailor the response characteristics of the amplifier for various listening environments. The incorporation of digital inputs via the DAC3 adds versatility without sacrificing the integrity of the analog signal, which is protected by high-quality coaxial cabling. The design also emphasizes meticulous ground paths and channel separation, ensuring minimal interference and optimal stereo imaging.

Key Features

• Triode and Pentode Modes: Enables user-selectable power output—30 W for smooth, warm sounds in triode mode or 50 W for dynamic headroom in pentode mode.
• Adjustable Feedback: Allows fine-tuning of the amplifier’s response characteristics, effectively managing distortion and enhancing clarity.
• Subwoofer Output: Unfiltered output maintains the amplifier’s sonic signature while connecting to an active subwoofer for deeper bass performance.
• Micro Relay Input Selection: High-precision micro relays enhance input switching reliability and preserve signal integrity during source changes.
• Advanced Inputs: Includes 3 analog inputs and advanced digital connections (USB, SPDIF, Toslink) through the DAC3, enabling high-resolution audio streaming without loss of quality.
