Offered is „Unison Research P30K Röhrenendstufe Röhrenverstärker - High-End!!“ by Unison Research as second-hand device from the category „Tube-Poweramp“ on audio-markt.de - the online market place for high-end. The advert with the number 7780829169 ends on 18.11.2026 at 13:08 o'clock.
This is a buyer’s market for this category at the moment, and this asking price looks like a strong deal. At €1,629, it sits well below the €2,062 median and under the €1,565–€2,981 spread’s middle ground, so it reads as attractively priced rather than merely fair.
That makes it especially interesting if the unit is clean and fully functioning, because these big Unison Research valve power amps are valued for their rich tone, scale, and musical ease rather than brute measurement-chasing. The upside is strongest if it comes from a careful owner with good packaging, recent service history, or original accessories; those details matter more than cosmetic perfection on gear like this.
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.
