£995 looks like a strong buy for a Unico Primo in today’s used market. New pricing has sat around the £1,700–£2,700 level depending on finish and market, so this is roughly in the lower half of used value and a lot easier to justify than a fresh purchase. For a current-model, well-known hybrid integrated, that’s a very sensible asking price if it’s clean and fully working.
What makes it appealing is the sound: the Primo is one of those amps people buy for its mix of tube sweetness and MOSFET grip, with proper drive, good bass control, and enough power to suit a wide range of speakers. The remote, dual speaker posts, and generally substantial build add to the value. At this price, I’d mainly want confirmation that the tube stage is healthy, the remote works, and there’s no evidence of noisy controls or intermittent input/output issues.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Unison Research, an Italian hi-fi icon, traces its roots to 1987, when it was founded in Treviso by Giovanni Maria Sacchetti, a visionary electronics engineer and music enthusiast born in 1945. Sacchetti, who balanced a career in teaching with amplifier design, assembled a team of dedicated audiophiles driven by a singular passion: delivering profound musical pleasure through superior sound. From its inception, the company emphasized handmade craftsmanship entirely within Italy, evolving under subsequent leadership like Giovanni Nasta while honoring Sacchetti's legacy of innovation in tube-based audio.
The brand excels in valve amplifiers, its core strength, with legendary models like the Triode 20—the first integrated amp Sacchetti designed—and the Simply Two, which sold over 30,000 units and propelled global acclaim. Early offerings included the Glowy preamp and Ruler power amp, pioneering designs such as the first stereo amplifier using the 845 triode. Today, Unison Research offers a focused lineup of preamplifiers, power amps, integrated amplifiers, and select speakers in partnership with Opera Loudspeakers, prioritizing pure analog warmth over digital peripherals like DACs or headphones.
Positioned as a high-end boutique leader, Unison Research reigns as Italy's top tube amplifier producer and ranks among Europe's elite ten. Audiophiles worldwide revere its products for their emotional depth, artisanal quality, and timeless appeal, cementing a niche among discerning buyers seeking authentic, soul-stirring hi-fi that transcends mere technical specs.
