Angeboten wird „Absolute 845 Integrierter Röhrenverstärker – Rarität & Top Zustand!“ von Unison Research als Gebrauchtgerät aus der Kategorie „Vollverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 5097954054 endet am 23.08.2026 um 08:49 Uhr.
This is a fair ask, and it’s slightly under the market’s center of gravity. At €5,250, it sits just below the €5,282 median and essentially on top of the €5,259–€5,304 interquartile band, so it reads as sensible pricing rather than a bargain or an ambitious ask.
That makes it interesting if the unit is genuinely clean and fully functioning, because this is a respected high-end tube integrated that’s prized for scale, tone density, and that big, effortless 845 presentation. In good condition, the upside is mostly in avoiding the usual tube-amp headaches: verify service history, valve age, and that it comes complete with all the original bits you’d want for a serious keep-it-for-years buy.
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.
