Angeboten wird „LS28 preamplifier“ von Audio Research als Gebrauchtgerät aus der Kategorie „Röhren-Vorverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 636442880 endet am 13.06.2026 um 14:45 Uhr.
€5,190 is slightly below the median of your comparable set, which sits at €5,521, so this reads as a fair-to-good buy rather than a bargain. It is comfortably inside the main market band and not far from the center of pricing, especially versus the €3,377–€7,928 interquartile range.
What makes it attractive is the LS28’s reputation as a very listenable line-stage: clean, open, and musically refined, with the kind of low-noise, full-bodied presentation that fits revealing systems well. A “good” condition example at this price can be a sensible entry if it’s serviced properly, but I’d still want confirmation of smooth control operation, quiet output, and recent maintenance on a piece from a brand where age-related service history matters.

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.
