About This Model
The Marantz ST320L is an AM/FM stereo tuner produced between 1982 and 1984, covering FM (87.5–108 MHz), MW (525–1605 kHz), and LW (150–350 kHz) bands — a notably broad tuning range that includes Long Wave, less common in tuners of this era. FM performance is well-specified for its class, with a sensitivity of 2.0µV, signal-to-noise ratio of 66dB, distortion of just 0.35%, and selectivity of 65dB, alongside a frequency response of 30Hz to 15kHz. The unit is built around a discrete semiconductor array of five ICs, 22 transistors, two FETs, and 16 diodes. In a slim 416 × 55 × 192mm chassis weighing 2.4kg, it fits neatly into a period or modern rack stack.
A great opportunity to own a Marantz ST320L at this price point.
The Marantz ST320L is a notable vintage tuner often paired with classic Coppia stereo amplifiers, prized for its clean FM reception and warm analog character. At US$56, this asking price is a massive bargain, sitting far below the 25th percentile of US$192 from 673 recent comparable USD listings where the median is US$415. This is an undeniable strong deal that buyers should not hesitate on.
This unit represents a top-tier buying opportunity because well-regarded Marantz tuners like the ST320L deliver excellent sound quality and reliable performance when maintained. The listing notes "Excellent" condition and a passed 7-point functional test, meaning the internal components are likely intact and ready for use. With no material caveats given the rock-bottom price and verified working status, this is a rare chance to acquire a beloved vintage piece at a price that defies typical market norms.

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.
