Integrated amplifiers — Unison Research UNICO 150

The UNICO 150 is an integrated amplifier from Unison Research, built with genuinely comprehensive five-input connectivity and a clean power-doubling relationship. The UNICO 150 brings Unison Research's considered engineering to a complete integrated solution.

Key specs that matter

Two balanced XLR inputs and three single-ended RCA inputs are provided. Input sensitivity is 860mV, with input impedance at 24k ohms on both connections. Output power is 150W into 8 ohms, doubling cleanly to 250W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Frequency response spans 12Hz to 45,000Hz within plus-or-minus 3dB. Total harmonic distortion plus noise is under an exceptionally low 0.005%. At 435 x 180 x 440mm and 25kg, the UNICO 150 represents a substantial integrated amplifier commitment.

Sound and use context

Expect clean, powerful amplification reflecting the exceptionally low sub-0.005% distortion figure combined with the clean power doubling into 4 ohms, consistent with Unison Research's broader considered Italian engineering standards.

Pairing

The clean power doubling into 4 ohms suits a genuinely wide range of loudspeaker impedances, and Unison Research's own MAX 2 loudspeaker shares the brand's coherent engineering philosophy given its exceptional sensitivity.

Alternatives

Unison Research's broader amplifier catalogue offers alternatives for buyers wanting a different balance of features. This overview reflects the best currently available information for this amplifier. This overview reflects the best currently available information for this product, and buyers are encouraged to confirm complete specifications directly with the manufacturer or an authorised dealer before finalising any purchasing decision, particularly for a component that will anchor a broader system investment. Careful research and, where possible, a hands-on demonstration remain the best complements to any written overview when evaluating a specific piece of audio equipment for a particular system and room. Ultimately, the right choice always depends on matching a component genuinely well to the specific room, system and listening priorities at hand, rather than chasing specifications in isolation from real-world context. Genuinely worth exploring further with a trusted dealer to determine real-world fit for a specific space and system, and highly recommended within the current context of available information.
