Unison Research Unico Pre v2

The Unison Research Unico PRE v2 delivers an unparalleled acoustic experience by remaining true to the natural sound of music. With its dual-mono topology and zero global feedback architecture, it exemplifies the essential principles of high-fidelity audio reproduction.

---

At the heart of the Unico PRE v2 lies a carefully crafted hybrid architecture that fuses the acoustic virtues of vacuum tubes with the precision of solid-state electronics. Utilizing a pair of ECC83 / 12AX7 Gold Lion valves in the first amplification stage, this preamplifier establishes a sonic character characterized by signal purity, exceptionally low distortion, and quiet operation, effectively minimizing noise floor and maximizing dynamic range. The subsequent solid-state stages complement the valve section, enabling robust signal processing even under adverse conditions. Additionally, the balanced design extends to the integrated DAC section with a Sabre ES9018K2M converter, optimizing phase coherence and harmonic balance across both analog and digital inputs. By employing high-precision resistors for volume control, Unico PRE v2 ensures impeccable channel matching and signal integrity, making it an exemplary choice for discerning listeners seeking authentic audio fidelity.

Key Features

• Zero Global Feedback Design: This approach minimizes inter-modulation distortion, preserving the integrity of audio signals across all frequencies.
• Dual-Mono Topology: By using separate circuits for left and right channels, the configuration enhances stereo imaging and minimizes crosstalk.
• High-Quality Volume Control: The precision resistors used allow for fine adjustments in volume levels, which maintains consistent channel balance and audio fidelity.
• Integrated DAC with Sabre ES9018K2M: Leveraging advanced digital-to-analog conversion, this DAC supports high-resolution audio with minimal latency and distortion.
• Selectable Load and Gain Settings in Phono Stage: Customizable configurations ensure optimal performance with different MM and MC cartridges, maintaining the quality of analog playback.
• Extensive Connectivity: With various input types including RCA, XLR, USB, and Toslink, the Unico PRE v2 can seamlessly integrate with a wide range of audio systems.
