Offered is „Simply 845 Kirsche“ by Unison Research as new device from the category „Tube-Fullamp“ on audio-markt.de - the online market place for high-end. The advert with the number 9142347119 ends on 23.12.2026 at 06:02 o'clock.
At €6,000, this is a fair ask right in line with the current used market, essentially sitting on the median rather than presenting a bargain or a stretch.
That makes it a sensible buy if the condition is genuinely clean: the Simply 845 is a highly regarded 23W single-ended triode integrated with big, authoritative tone, excellent flow, and the kind of dimensional midrange and natural dynamics that reward efficient speakers. It’s also a distinctive, full-size statement piece with real enthusiast cachet, so a tidy example at this price is attractive. The main thing to check is the usual tube-amp housekeeping: service history, tube life, bias stability, and whether it’s complete with original packaging and accessories.
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.
