Offered is „Phono One - Kirsche, incl. Netzteil“ by Unison Research as exhibit from the category „Phono Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 1631647377 ends on 06.11.2026 at 06:32 o'clock.
The Phono One has a strong reputation as a serious, all-tube phono stage, and €2,349 lands below the usual used and even many current retail asks I found for the model. With a second-hand ask around €3,200 and new pricing commonly around €2,849–€2,300 in the sources, this listing looks good value rather than ambitious.
What makes it appealing is the classic Unison mix of rich tone, solid gain for MM/MC use, and real-endgame build quality; it’s the sort of phono stage people buy to keep. Included cables and accessories are a plus, and at “good” condition this reads as a sensible buy if it’s fully functional and still quiet. If the power supply and tubes are healthy, the package has genuine upside for a vinyl-focused system.
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.
