A$4,850 looks like a strong deal versus the current used market: it sits well below the A$6,454 25th percentile and far under the A$8,057 median, so this is priced on the attractive side rather than merely fair. For a Krell KSA 100s, that kind of gap is meaningful in a market where comparable examples are already asking materially more.
The appeal here is straightforward: this is one of Krell’s classic high-current muscle amps, prized for grip, scale, and the ability to drive difficult speakers with real authority. If the unit is clean and fully working, the upside is getting that kind of heavyweight, old-school performance at a sub-quartile price. I’d mainly want confirmation on service history, channel balance, and whether it has been recapped or needs attention, because age and heat-stressed parts matter more than cosmetics on this model.

Krell Industries, founded in 1980 in the United States by Dan D'Agostino and his wife Rondi, emerged from a passion for pushing audio engineering boundaries. Based initially in Bridgeport, Connecticut, and later settling in nearby Orange, the brand drew its name from the advanced alien race in the 1956 film Forbidden Planet, symbolizing limitless technological power. The company's debut at the 1981 Consumer Electronics Show with the KSA-100, a high-power Class A amplifier, sparked immediate demand and established Krell as a force in American hi-fi innovation.
Krell specializes in high-end amplification, with its power amplifiers—epitomized by flagships like the Master Reference Amplifier—earning legendary status for their raw dynamics and precision. The lineup extends to preamplifiers, surround sound processors, digital-to-analog converters, CD and Super Audio CD players, loudspeakers, and subwoofers, all engineered for uncompromised performance in music and home theater systems.
Positioned firmly at the pinnacle of the high-end audio market, Krell commands respect among discerning audiophiles for its cutting-edge circuitry, massive power supplies, and relentless pursuit of sonic excellence. A top-tier brand alongside legends like Levinson and Threshold, it appeals to buyers seeking reference-level gear that defines the genre, even amid recent ownership transitions following Rondi's passing in 2024.
