NAD Electronics 218 THX Power Amplifier This is a 25 year old amp but it is virtually unused and in its original box. See here for Stereophile's glowing review: https://www.stereophile.com/solidpoweramps/899nad/index.html 225W into 8 ohms but able to be bridged to yield 780W. If anyone is interested in supplying 1560W to your speakers, I actually have 2 of these bad boys (the second one is without a box). Let me know and we can discuss a price. Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.03% Damping factor: 200 Gain: 29 dB Input sensitivity: 1.5V Signal to noise ratio: 1
This is a buyer’s market at this asking price: A$1,000 sits below the 25th percentile of your comparable AUD listings at A$1,068, so it reads as a strong deal rather than merely fair. Against the median of A$1,137, the discount is meaningful, and it is comfortably under the upper quartile at A$1,206.
That makes it an appealing buy for anyone after a respected high-current-power amp with real hi-fi credibility and THX pedigree. The upside is straightforward: solid build, serious drive, and the kind of controlled, authoritative presentation that suits demanding speakers well. With condition listed as unknown, I’d just want confirmation it powers up cleanly, has no channel imbalance or relay issues, and hasn’t been abused thermally; if those basics check out, this looks like a tidy pick-up.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
NAD Electronics was founded in 1972 in London by a group of European audio importers frustrated with the hype surrounding Japanese hi-fi products. Led by visionary American executive Martin L. Borish and brilliant engineer Bjorn Erik Edvardsen, the company emerged from a quest to deliver high-performance audio at accessible prices. Their breakthrough came with the NAD 3020 integrated amplifier, the best-selling hi-fi amp in history, which embodied a philosophy of stripping away non-essentials to prioritize pure sound quality.
The brand focuses on core hi-fi categories, excelling in amplifiers—pioneering Class A/B, Class G, and hybrid digital designs—alongside integrated receivers, AV processors, turntables, CD and cassette players, and modern streamers. While not venturing into speakers, headphones, or cables, NAD emphasizes source components and amplification that integrate seamlessly into home theater and custom installation setups, always upholding principles of innovation, simplicity, performance, and value.
Today, as part of Canada's Lenbrook Group and sold in over 80 countries, NAD holds a commanding mid-tier position in the market, revered by audiophiles for affordable excellence rather than ultra-high-end excess. Its "Truth in Power" legacy earns cult status among knowledgeable buyers seeking reliable, award-winning gear that punches above its price, blending vintage heritage with contemporary streaming and hybrid tech.
