About Unison Research

Unison Research, founded in Italy, has a long-standing reputation for crafting high-fidelity audio equipment that marries traditional craftsmanship with cutting-edge technology. Each product reflects their passion for music and dedication to producing equipment that delivers both sonic excellence and visual beauty. 

Design and Build

The Preludio features a thoughtful design that prioritizes both aesthetics and functionality. The top plate, made from magnetic stainless steel, is designed to minimize heat conduction, ensuring that the internal circuitry remains unaffected by the heat generated by the 6550 tubes. This attention to detail extends to every component, from the circuit boards to the control knobs, resulting in an amplifier that is as reliable as it is beautiful.

Performance

Though rated at 14 watts per channel, the Preludio’s Pure Class A design allows it to perform like a 40-50 watt solid-state amplifier, driving most speakers with ease. It excels in delivering a natural and dynamic sound, making it ideal for acoustic music, jazz, and blues. The amplifier’s ECC82 valves in the input stage and 6550 output valves ensure a warm and detailed audio experience.

Versatility

The Preludio is equipped with four line-stage inputs, a tape input, and an output, offering flexibility in various setups. The inclusion of full remote control functionality enhances usability, making it easy to integrate into your existing system. While it may not suit those seeking a powerhouse amplifier for high-volume rock or classical music, it shines in more intimate listening environments.

Speaker Compatibility

With any valve amplifier, speaker choice is crucial. The Preludio pairs well with speakers that have a sensitivity of 90dB or higher and an impedance that doesn’t drop below 4 ohms. For those unsure about speaker compatibility, our team at The Listening Room is available to offer expert advice.

Design Aesthetics

The Preludio’s design reflects its Italian origins, with an elegant finish available in Cherry. The combination of wood and brushed aluminum details adds a touch of sophistication to any listening room. Positioned in the middle of Unison Research’s range, the Preludio offers significant benefits over entry-level models like the Simply Italy, while still remaining accessible.

We provide expert advice, personalized service, and a commitment to helping you find the perfect sound system for your space.
