The timing matters because the M77 is an older, no-longer-new flagship-era Kondo line preamp, so value is driven more by condition, voltage, and completeness than by any “latest model” premium. At €800, this is dramatically below the usual used level for a Kondo M77, which has shown up around €18,800 used in Europe, and it would be a standout bargain if the listing is genuine and functional.
That price makes sense for a buyer who wants Kondo’s strengths: exceptionally refined tone, low-level detail, and that effortless, musical presentation the brand is known for. It’s especially appealing if it’s an original 230/240V unit, has the phono stage, and comes with proof of service or careful ownership. At this level, the main thing to verify is not sonic quality but basic health: tube condition, hum/noise, and whether all inputs, controls, and the power transformer are healthy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# Kondo Audio Note Japan
Kondo Audio Note Japan was founded in 1976 by Hiroyasu Kondo, a metallurgist and son of a Buddhist priest whose technical expertise and philosophical approach to sound reproduction shaped the company's identity. Based in Japan, the brand has maintained its independence and commitment to handcrafted manufacturing for nearly five decades, recently adopting the "Kondo" name to reflect its founder's central role in the company's vision and legacy.
The brand is renowned primarily for vacuum-tube amplification, particularly its legendary power amplifiers and preamplifiers. The 1989 Ongaku power amplifier stands as a watershed moment in high-end audio history, establishing Kondo's reputation for sonic refinement and technical innovation. The company also manufactures integrated amplifiers, preamplifiers like the iconic M7 Heritage, and proprietary capacitors—all produced through meticulous, point-to-point hand-wiring and manual assembly processes that prioritize component quality over production volume.
Kondo Audio Note Japan occupies the ultra-premium tier of the hi-fi market, commanding prices that reflect its artisanal manufacturing, exotic component selection, and uncompromising design philosophy. The brand appeals to dedicated audiophiles and collectors who value emotional engagement with music reproduction and are willing to invest substantially in equipment that combines technical excellence with aesthetic and sonic character. Its reputation rests on exclusivity, heritage, and an unwavering commitment to analog-era design principles adapted for contemporary listening.
