Should you jump on a US$75 ask for this, or is it too cheap to trust? Against your own market data, it’s a strong bargain: US$75 is far below the US$1,200 25th percentile and a tiny fraction of the US$2,000 median, so this is priced like a quick move rather than a normal sale. That makes it the kind of listing a buyer should pounce on if the photos and details check out.
What makes it interesting is the combination of rarity and real-world usefulness: these external crossover units were bought to let a Magnepan setup behave properly, so when they’re authentic and intact they can be hard to replace. If it’s complete, unmolested, and still presentable, the upside is obvious at this price; just verify the exact model, connectors, and whether any damage or modifications are hiding in the fine print.

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.
