Angeboten wird „Absolute 845 Integrierter Röhrenverstärker – Rarität & Top Zustand!“ von Unison Research als Gebrauchtgerät aus der Kategorie „Röhren-Vollverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 8784153705 endet am 13.08.2026 um 14:29 Uhr.
The timing matters a bit: this is an established high-end integrated from an earlier era, so value is more about condition and provenance than chasing a newer replacement model. At €5,250, it lands just under the €5,279 25th percentile and below the €5,301 median, so this reads as a solid buy rather than a merely fair ask.
That’s the right zone for a piece like this: Unison Research’s big 845 integrateds are admired for their authoritative, spacious sound and the kind of triode drive that still feels special. If the listing is genuinely good and complete, the small discount versus the median makes it attractive; for a tube amp of this caliber, clean cosmetics, recent service, and included accessories matter more than shaving another few hundred euros.
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.
