New, this was a serious multiroom amplifier rather than a bargain-basement component; at US$119 used, it sits well below the comparable-sales 25th percentile of US$143 and far below the US$261 median. That makes it a genuine bargain, assuming the “mint” description is accurate and it is tested.
The Z-660’s appeal is its unusually useful six-channel layout: 60 watts per channel, with adjacent channels bridgeable to three 120-watt outputs. It also offers RCA inputs and loop outputs, making it handy for distributed audio, multiple stereo zones, or a compact custom installation. The slim chassis and robust toroidal-powered design add practical value. At this money, confirm all six channels work, bridging operates correctly, and the required binding-post hardware or rack accessories are included—but a clean, functioning example is an excellent buy.

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.
