Audio Research Reference 110 Power Amplifier This beautiful Amplifier has been fully rebuilt with all new Mundorf capacitors, KT120 and 6H30Pi tubes. Has such a sweet warm sound with slam and authority. Awesome bass and amazing detail and resolution. One of the best tube amps i've ever heard. Condition: Excellent Payment Method: Paypal, EFT, Cash on Pickup Region/State: (VIC) Victoria/Australia By Audirvana 0 Comments AUD $5,500 Date: September 27, 20241 yr
The Reference 110 is a serious, well-regarded Audio Research tube power amp, and A$5,500 in excellent condition looks fair to slightly strong, not a bargain-basement steal but still very buyable. Recent used asks/sales cluster around A$5,500–A$5,900 in Australia, while overseas examples often land in a broadly similar band once converted, so this listing sits right around the middle of the market rather than above it.
That makes it attractive if the unit is genuinely clean and complete: the REF 110 is prized for big, authoritative drive, open mids, and that classic ARC balance of finesse and scale. At this price, I’d especially value original packaging, fresh tubes, and proof it’s been maintained properly; if those are in place, this is a solid enthusiast buy with real musical upside.
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.
