Offered is „Unico Due“ by Unison Research as exhibit from the category „Fully integrated Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 829311201 ends on 20.11.2026 at 09:15 o'clock.
At €2,250, this sits right on the money for the recent used market: basically the median of €2,268 and comfortably within the tight €2,247–€2,276 band. That makes it a fair buy rather than a bargain, but not an ambitious ask.
The appeal here is straightforward: Unison Research pieces are usually bought for their musical, polished presentation and build quality, and the UNICO line has a solid reputation with listeners who want a smooth, engaging digital front end. In good condition at this price, it looks like a sensible opportunity for someone who wants the sound and the brand without paying a premium; just make sure the usual CD-player basics are healthy—disc loading, tray action, and stable playback.
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.
