Audio Research DSi 200 Integrated Amplifier (Solid State) Rare High Definition Series integrated amp from the most recognised and revered high end electronics brand in audio history. This model has flown under the radar a bit because it's not a valve model like the ones that earned ARC its reputation. Nevertheless, anyone who has lived with this amp will recognise that it leaves little to be desired in comparison with tube models, and typically surpasses them in aspects like bass impact and control, while requiring no maintenance. Audio Research call this model a fully balanced "hybrid solid-s
Against your recent AUD comps, A$3,780 sits well above the 75th percentile of A$3,301, so this is an ambitious ask rather than a fair-market buy. It’s roughly A$495 over the top quartile and A$895 above the median A$2,885, so I’d only lean in if the unit has unusually strong provenance or extras.
That said, the DSi200 is a serious integrated: a big, authoritative solid-state amp with the kind of control, scale, and effortless drive Audio Research buyers tend to chase. If it’s clean, fully original, and comes with remote, packaging, or proof of recent servicing, there’s real upside for a buyer who wants to skip the hunt and get straight to listening.

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.
