Offered is „S6 MKII 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 594701371 ends on 23.12.2026 at 06:23 o'clock.
A clean-looking Unison Research S6 at €2,720 sits right on the median of recent used asking prices, so it reads as fair rather than a steal. It’s comfortably below the upper end of the market, where comparable listings are around €4,366, so there’s no reason to expect a discount beyond normal negotiation.
The S6 is well liked for its rich, spacious valve sound with real grip and drive for a tube integrated, plus attractive build quality that still feels special on a rack. At this price, the appeal is strong if the amp is healthy and complete; just make sure the tubes are in good shape and that any original remote, crate, or paperwork is included, since those add real value.

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.
