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 4065556635 ends on 23.10.2026 at 08:51 o'clock.
This is a buyer’s market at this price: at €2,250, it sits just above the €2,216 median and a touch over the €2,236 75th percentile, so it’s fair-to-slightly firm rather than a bargain. It is not overpriced, but there’s no big discount here either.
What makes it worth a look is the Unico’s reputation for a smooth, musical presentation and strong build, especially for buyers who want a one-box digital front end with an easy, engaging sound. In good condition, that matters more than shaving a small amount off the median; just confirm transport health, laser behavior, and that it includes the remote and any original packaging, since those details help protect resale value on a higher-ticket used piece.
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.
