Angeboten wird „Classic 120 SE - ex demo - special export price“ von Conrad Johnson als Ausstellungsstück aus der Kategorie „Röhren-Endverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 6995341030 endet am 05.09.2026 um 06:16 Uhr.
The Conrad-Johnson Classic 120 SE is a sought-after vintage integrated amp, prized for its warm, tube-driven soundstage that excels with vocals and jazz. On the used market, recent comparable listings cluster tightly around a median asking price of EUR 3,990 (25th percentile EUR 3,595, 75th percentile EUR 5,016), reflecting solid but not stratospheric demand for good-condition units. At EUR 9,500—even as an ex-demo—this strikes me as ambitiously priced, nearly double the 75th percentile; you'd need pristine cosmetics, recent servicing, and proof of low hours to justify it over hunting fresher alternatives.
Before biting, verify the tube complement (original Mullards or JJ substitutes?) and bias settings, as these amps can drift with age and demand recalibration to avoid channel imbalance. Also insist on service records and a burn-in test for hum or microphonics—common gremlins in 20+ year-old C-Js without recent love.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Conrad-Johnson emerged in the mid-1970s from the dissatisfaction of two American economists and audiophiles, Dr. William Conrad and Dr. Lewis Johnson, with the inconsistent performance of contemporary amplifiers. Founded in the United States, the company launched its inaugural product, the all-vacuum-tube PV-1 preamplifier, in 1977, quickly earning critical acclaim and establishing a benchmark for musicality. This debut propelled Conrad-Johnson into the forefront of the tube renaissance, with the iconic MV75 power amplifier following in 1978, solidifying its heritage as a pioneer in high-end audio craftsmanship.
The brand specializes in vacuum-tube preamplifiers and power amplifiers, renowned for their warm, engaging sound that prioritizes musical satisfaction over sterile measurements. While tube designs remain its cornerstone, Conrad-Johnson expanded into solid-state amplifiers and phonostages in the 1980s, alongside limited ventures like the Sonographe turntable line and electronics acquired in the late 1980s. All components are hand-built in the USA using simple circuits and premium custom parts, reflecting over four decades of refined design philosophy.
Conrad-Johnson holds an exalted position in the high-end market as an American classic, beloved by audiophiles for gear that "just sounds right." Its products command lust among enthusiasts worldwide, blending vintage appeal with sustained relevance, and consistently rank among the most musically rewarding options available.
