For sale one PAIR of Marantz Model 9 mono block amplifiers (original version) in very good condition as pictured. Serviced (by previous owner) at Absolute Sound labs about 12 years ago. I have owned them since 2018 and the amps have performed just fine in my home since I purchased them in 2018. They are fantastic sounding and it has been a pleasure listening to them but time to move on. Included are 8 Sylvania EL34 6CA7 "OO" Getter Welded Plates Fat Bottle output tubes that Test Strong. Each amp weighs 67lb and are packaged securely and separately. Upon purchase, there will be shipping of 3 boxes total (2 with the amps and 1 with the tubes, front Marantz plates and literature).
The asking price of US$9,370 for the Marantz Model 6-G speakers is vastly ambitious, exceeding the 75th percentile of US$2,481 by nearly four times and sitting far above the median of US$1,000. This listing is not a bargain but a severe overprice compared to the typical used market, where comparable units often trade between US$600 and US$2,481.
Despite the Marantz Imperial 6 being a solid two-way vintage speaker that can sound lovely with upgraded tweeters and capacitors, the price here destroys any buying opportunity. The genuine upside of rarity or original-owner condition is negated by the inflated cost, making this a risky purchase unless the condition is mint and accessories are pristine, which remains unconfirmed in the listing. Buyers should avoid this unless the price drops significantly toward the US$1,000 median.
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.
