Is US$1,100 a bargain for this vintage preamp, or a trap? Given that the original 1991 LS2 retailed for US$2,495 and a similar vintage unit recently sold for US$1,300 with box and manual, this asking price sits below the 25th percentile of the typical used market, making it a genuine bargain for a well-regarded 1991 hybrid tube preamp.
This Audio Research LS2 is a worthwhile buy because it delivers the warm, musical sound of its era with a clean, low-noise hybrid design that pairs 6H30 triodes with FET coupling for excellent drive. Its upside includes the likelihood of original-owner condition and the rarity of a fully functional vintage unit from a respected American brand, offering immediate high-end performance without the need for modern upgrades.
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.
