Angeboten wird „PH-9“ von Audio Research als Ausstellungsstück aus der Kategorie „Phonoverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 1384810242 endet am 02.09.2026 um 12:10 Uhr.
Condition noted as good, €6,400 is fair-to-strong rather than cheap: the PH9 is a current-model Audio Research phono stage with a much higher new price, and used examples still tend to sit well above this level when clean and working. With that in mind, this looks like a sensible buy if you want a serious step-up phono stage without paying new-retail money.
What makes it worth the spend is the PH9’s reputation for a big, composed, highly resolving presentation with real drive and tonal color, which is exactly why it stays in demand. A good-condition example at this price is attractive if it’s complete, quiet, and has healthy tube life; the main thing I’d verify is service history and whether any original packaging, remote, or spare tubes are included, since those matter more than minor cosmetics on a piece like this.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Audio Research Corporation, founded in 1970 in Minneapolis, Minnesota, by William Z. Johnson, traces its roots to his pioneering work in custom audio electronics during the 1950s and his operation of a specialty retail store through the mid-1960s. After a brief stint selling his designs to a larger firm, Johnson regained independence to establish ARC with a singular mission: advancing the state-of-the-art in music reproduction. From modest beginnings in the back of his shop, the company evolved into one of America's oldest continuously operating high-end audio manufacturers, now housed in a state-of-the-art 48,000-square-foot facility in Maple Grove, Minnesota.
ARC specializes in performance-driven electronics, renowned for vacuum-tube amplifiers, preamplifiers, and electronic crossovers that emphasize sonic purity over flashy features or aesthetics. Drawing on circuit designs rooted in the 1950s, the brand integrates tubes into modern contexts, delivering what it calls "high definition" sound through genuine technological advances. While not venturing into speakers, turntables, DACs, headphones, or cables, ARC's focused lineup prioritizes amplifiers and preamps that set benchmarks for musical realism.
Positioned at the pinnacle of high-end audio, Audio Research is hailed as a true originator of the genre, commanding respect among audiophiles for its unwavering commitment to excellence and innovation. Enduring the 1970s tube revival against solid-state dominance, ARC thrives via elite specialist retailers worldwide, standing alongside peers like Conrad-Johnson as a vintage-inspired yet forward-thinking force in the niche boutique market.
