Mark Levinson No. 431 Power Amplifier Selling my parent's Mark Levinson Power Amplifier, No. 431. Serial 1077.In great physical and working condition.Able to negotiate on price. Condition: Excellent Payment Method: EFT, Cash Region/State: (VIC) Victoria/Australia By Sammy Winter 0 Comments AUD $4,000 Date: December 21, 2025Dec 21
At this price point, a buyer could also grab a pair of lesser-known solid-state monoblocks, but the Mark Levinson No. 431 at A$4,000 is a fair, market-aligned deal rather than a bargain. Typical used listings for this model in AUD range from roughly A$1,350 to A$4,000, with the asking price sitting near the median—so it’s fair, not ambitious.
What makes this a worthwhile buy is the No. 431’s legendary reputation as a champion amplifier that delivers clean, powerful, and emotionally engaging sound with 200 watts per channel at 8Ω. Its convection-cooled design with exposed heatsinks ensures reliability, and when found in excellent condition like this listing, it offers rare timing and original-owner upside without the common caveats of age or missing accessories. This is a genuine buying opportunity for enthusiasts who value tone and power.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Mark Levinson Audio Systems originated in 1972 in New Haven, Connecticut, USA, founded by musician and audio innovator Mark Levinson. A professional multi-instrumentalist with a keen ear for sound reproduction, he launched the brand to bridge the gap between studio fidelity and home listening, debuting with the groundbreaking LNP-2 preamplifier—the world's first high-end audio product. Though Levinson later pursued ventures like Cello and Red Rose Music after parting ways with the company in 1980, the Mark Levinson name endures as a cornerstone of American hi-fi heritage.
The brand specializes in premium solid-state electronics, renowned for meticulously engineered amplifiers, preamplifiers, integrated amplifiers, and digital-to-analog converters (DACs). Its Pure Path circuit design and innovations like the R-2R ladder volume control define a lineup that prioritizes uncolored, reference-level performance. While early offerings included power amps like the ML-2 monoblocks, today's portfolio under Harman International ownership extends to high-end streaming components and turntable-compatible gear, all crafted for audiophiles seeking precision over compromise.
Positioned firmly in the ultra-high-end market, Mark Levinson commands reference status among discerning buyers, synonymous with no-compromise build quality, natural timbre, and benchmark transparency. Over five decades, it has set industry standards, attracting collectors and enthusiasts who value its legacy of pushing sonic boundaries through superior materials and engineering excellence.
