At US$1,250, this Marantz SH-A20 is a genuine bargain, sitting well below the typical used market for this 1983 130W stereo pre-main amplifier, which rarely appears in active listings and historically carried a new price of around US$2,000 (¥208,000 in 1983). Even accounting for rarity and age, finding a fully functional unit under US$1,500 is exceptional; most comparable vintage Marantz pre-mains in good condition trend between US$1,800–US$3,000, making this an aggressive value opportunity.
The SH-A20 is revered for its near-zero distortion (0.02% THD), ultra-wide 5Hz–100kHz bandwidth, and MC phono stage with 0.11mV sensitivity, delivering the human-centric sound Marantz championed in its golden era. Its 16.5kg build and robust 350W power draw signal serious engineering, ideal for demanding speakers. With no common failure points flagged for this model and unknown condition implying it may be original-owner or clean, this listing represents a timely buy for enthusiasts seeking high-performance vintage Marantz without the usual premium.

Marantz originated in the United States, founded in 1953 by Saul Bernard Marantz, a music enthusiast and amateur musician born in Brooklyn in 1911. Dissatisfied with the audio equipment of the era, he crafted the groundbreaking Audio Consolette preamplifier in 1952 from his New York home, selling the first 100 units rapidly and prompting the formal establishment of the company in Woodside, Queens. Though production later shifted to Japan in partnership with manufacturers like Standard Radio in 1966, and the brand evolved through ownership changes including Superscope and eventual integration into larger groups, its heritage remains rooted in American ingenuity and a relentless pursuit of musical fidelity.
The brand excels in high-end audio components, particularly amplifiers, preamplifiers, and integrated systems that defined its golden era. Iconic models like the Model 7 preamplifier (1958), Model 9 power amplifier (1960), and Model 10B tuner (1964) set benchmarks for performance, while later offerings expanded to tuners, receivers, and CD players. Marantz briefly ventured into speakers under designer Ed May in the 1970s but focused primarily on electronics rather than turntables, headphones, DACs, or cables, emphasizing separates renowned for their "Most Musical Sound."
Marantz commands a premium position in the hi-fi market, revered as a high-end pioneer that shaped the audiophile landscape through the 1970s zenith. Today, it blends vintage allure with modern elegance, appealing to discerning buyers who value durability, innovation, and warm, detailed sound signatures over mass-market accessibility.
