Against a new integrated or a smaller modern power amp at this level, £1,750 looks very good for a VT100. Typical used pricing for the VT100/VT100 Mk III family has been around £2,700-£3,000 in the wider market, so this sits below that and reads as a genuine buying opportunity rather than an ambitious ask.
What you’re buying is a classic 100W per channel Audio Research tube amp with the big, controlled, spacious presentation these are known for, plus balanced inputs and serious current capability for a tube design. If it’s clean, properly biased, and comes with recent tubes or service history, the upside is strong because these are substantial, long-lived amps; the main thing to confirm is condition and maintenance, since old tube gear is only as good as its bias, output tubes, and support circuitry.
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.
