Angeboten wird „LS28“ 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 6605167395 endet am 17.08.2026 um 08:53 Uhr.
Against your EU comps, €5,199 lands exactly on the median, so this reads as a fair, market-level ask rather than a bargain or an inflated price. It is comfortably above the 25th percentile at €4,822, but still well below the upper end of the recent range at €6,623, which makes it a sensible buy if the unit checks out.
That price is reasonable because the LS-28 sits in Audio Research’s respected modern tube line: it’s known for strong resolution, a big, open soundstage, and the kind of dimensional midrange ARC owners buy these preamps for. At a fair ask, the value comes down to condition, tube hours, service history, and whether the original packaging, remote, and manual are included; those details matter more here than trying to squeeze a discount.
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.
