Commercial Marantz Model 30 Integrated Amplifier (Solid State) The Marantz Model 30 Stereo Integrated Amplifier is a beautifully engineered, audiophile-grade amplifier, offered here as an ex-demonstration model in excellent condition. Delivering 100 watts per channel into 8 ohms (and 200 watts into 4 ohms), its fully discrete, dual-mono design combines Marantz’s custom HDAM-SA3 analogue stages with high-performance Hypex Class D output modules for exceptional power, control and musicality. Tuned by Marantz Sound Master Yoshinori Ogata, the Model 30 is voiced by ear for a rich, natural and enga
The asking price of AUD 3,390 sits above your comparable median of AUD 2,982—about 13.7% higher—and notably above the 75th percentile at AUD 3,317. That's ambitious territory unless this particular unit is in exceptional condition or includes desirable original packaging and documentation. The Marantz Model 30 is a respected integrated amplifier with solid build quality, but the "unknown condition" flag is a red one here. At this price point, you're paying near the top of your local market range, so condition really matters; a unit showing wear, age-related degradation, or requiring servicing could easily tip this into overpriced territory.
Before committing, verify the amplifier powers up cleanly without hum, distortion, or channel imbalance at moderate volumes. Check that all inputs and the volume pot respond smoothly without crackling. Inspect the chassis for corrosion or previous repairs, and confirm the output transformers aren't leaking. Ask whether it's been serviced recently or if the capacitors have been recapped—these aging components often need attention on vintage gear. Make sure any original remote, documentation, or accessories are included; their absence would further justify walking away at this asking price.

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.
