Our Thoughts RADAR AI

At kr 8,000, this looks like a very strong buy for a Classic 150 if it’s genuinely working and reasonably presentable. Comparable asking prices I found cluster around the equivalent of roughly kr 35,000–kr 40,000, so this sits well below normal used-market territory rather than merely “a bit keen.”

That’s a respected ARC design with real heft and proper tube-drive charm: big, authoritative, and refined enough to make demanding speakers interesting. The upside here is obvious if it’s complete and stable—especially with original packaging, fresh tubes, or recent service history. Because these are old and heavy tube amps, I’d still verify bias stability, channel balance, and that there’s no transformer hum or noisy caps before jumping, but the price leaves plenty of room for sensible maintenance.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Audio Research

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.
