Lots of class A power with incredible dynamics. Comes with original wood remote. Out...
This is a buyer’s market for this category right now, and the A$2,000 asking price for the Unison Research Unico Secondo is a genuine bargain. While the original UK retail was £1,860 (roughly A$3,600), typical used pricing for this hybrid integrated in Australia sits between A$2,400 and A$2,800. At A$2,000, you are well below the 25th percentile, making this a strong deal for a well-loved model.
The Unico Secondo is highly regarded for its energetic, vital sound that blends tube warmth with MOSFET power, delivering 100W into 8Ω with exceptional dynamics. Its optional phono stage adds meaningful versatility for vinyl lovers, and the double ECC83/12AX7 tube input stage ensures rich tonality. If this listing is from an original owner in clean condition with accessories included, it’s a rare opportunity to secure a high-performance hybrid amp at a price that reflects true value rather than seller optimism.

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.
