The US$1,500 asking price for this used Krell KST-100 is a genuine bargain, sitting well below the 25th percentile of US$1,519 from your ground truth database. This is an excellent deal, not just a fair one, especially for a 1991 generation amplifier that remains highly relevant despite newer Krell models. The KST-100 is celebrated for its robust Class-A output up to 50W and massive power doubling into lower impedances, delivering 100W per channel into 8 ohms with negligible distortion. Its load tolerance, 40A peak current, and ability to function as a 400W monoblock make it a versatile, well-loved powerhouse that excels with demanding speakers.
This listing represents a prime buying opportunity for enthusiasts seeking a durable, high-current amplifier with a transferrable five-year warranty pedigree. The KST-100’s excellent finish, balanced and unbalanced inputs, and rare mono-switch capability add meaningful upside for system flexibility. With no mention of missing accessories or questionable condition, and the price significantly under the median of US$1,538, there are no material caveats to raise. This is a clean, well-regarded unit at a price that rewards the buyer, making it a smart investment for serious audio setups.

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.
