A Marantz SR770 at AUD 500 is hard to call a bargain without more detail, because this is an older AVR whose used value is driven more by condition, channel count, and whether it’s fully functional than by original pricing. For a legacy Marantz receiver in clean, proven working order, AUD 500 lands around fair-to-ambitious rather than obviously cheap; I’d want to see it closer to the low hundreds if it’s very plain or needs any attention.
That said, the upside is the Marantz house sound and solid build quality: these older units can still be very satisfying for 2-channel music or a basic surround setup if you’re not chasing modern HDMI/Atmos features. The key checks are all practical—remote included, all inputs working, no noisy relays or crackly controls, and no evidence of overheating. If it’s been cared for and the seller can demo it, it could still be a worthwhile buy for someone wanting a sturdy vintage-ish AVR.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
