Offered is „Sinfonia - Cherry“ 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 705535605 ends on 02.11.2026 at 06:11 o'clock.
This is a buyer’s market for high-end tube integrateds right now, and the €4,390 asking price for the Unison Research Sinfonia is a fair deal that sits just €6 below the median of €4,396 from recent comparable EUR listings. It lands comfortably between the 25th percentile (€3,460) and 75th percentile (€4,850), meaning you’re paying typical market value rather than overpaying or getting a bargain, but the price is solid for a unit listed as “new” in EUR condition.
The Sinfonia is well-regarded for its pure Class-A, all-tube design delivering 25–27W per channel with natural tonality and spacious sound, powered by premium Genalex Gold Lion KT88s and ECC tubes. Its dual-mono architecture, automatic bias, and Italian craftsmanship make it a timeless integrated for small-to-medium rooms. At this fair price, especially in near-new condition, it’s a buying opportunity for enthusiasts seeking refined tube sound without new-retail premiums (new retail is ~€6,600 for the LE Anniversary, and standard models often list near €6,500–€7,000).

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.
