Can include some BNC adaptors if asking price is paid. Can post at cost price. Condition: As New / Mint Payment Method: Cash on Pi
Like new is exactly how I’d want to see one of these, and at A$575 this looks fair to slightly strong versus the old new price of about A$760 equivalent from QuantAsylum’s retired-listing pricing, with used examples I’ve seen usually landing lower when the box is just the unit. It’s not a steal, but it’s close enough to retail that clean condition and accessories matter a lot.
The appeal here is real: the QA402 is a compact two-channel audio analyzer with serious measurement chops for DACs, amps, and phono stages, and its full-scale input/output flexibility makes it genuinely useful on a bench. If it includes the original leads, calibration file, and USB cable, that supports the ask; if it’s just the bare unit, I’d want a bit more discount.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
RCA traces its origins to 1919, when the Radio Corporation of America emerged from a U.S. government-backed reorganization of the Marconi Wireless Telegraph Company of America, prioritizing national security in radio technology. Born in the United States amid post-World War I innovation, the company lacked a single notable founder but was propelled by visionaries like David Sarnoff, who foresaw radio's mass-market potential. Its heritage spans a century of pioneering milestones, from acquiring the Victor Talking Machine Company in 1929—bringing the iconic "His Master's Voice" Nipper dog trademark—to launching early television at the 1939 New York World's Fair and shaping Nashville's recording scene through RCA Studios.
Historically a titan in consumer electronics, RCA focused on radios, phonographs like the famed Victrola, records, and later innovations such as eight-track tapes and magnetic recording. Today, under VOXX International, the brand emphasizes accessible audio-video accessories, including speakers, turntables, headphones, and portable systems, rather than specialized hi-fi components like amplifiers, DACs, or high-end cables.
RCA holds a venerable position as a vintage icon and entry-level mainstay, evoking mid-20th-century American living rooms rather than high-end audiophile pursuits. Its reputation rests on reliable, value-driven performance for everyday listeners, appealing to nostalgia seekers and budget-conscious buyers over niche boutique or collector-grade exclusivity.
