Description

Part of our classic line of tube amplifiers that include the Sinfonia and the Performance, the Preludio integrated amplifier continues the technical approach, sound and aesthetics of its larger siblings. While the Preludio’s appearance is certainly gorgeous, it is also extremely reliable due to its unique design solutions, quality materials and adherence to the highest of standards.

The Unison Research Preludio is a highly acclaimed, Italian-made single-ended Class A valve integrated amplifier (approx. 14W per channel) known for its superb midrange, lush vocals, and elegant aesthetic featuring cherry or mahogany wood accents. It excels with acoustic, jazz, and blues music, offering a surprisingly dynamic, punchy, and refined sound despite its lower power rating.
