Is US$1,575 a smart entry for a Krell KST-100, and does it beat the current used market? Yes, this asking price is a solid deal, sitting just US$37 above the median of US$1,538 from your two recent comparable listings and well below the 75th percentile of US$1,556. It lands in the upper end of the fair range but remains competitive given the KST-100’s reputation as a 100Wpc Class A/B powerhouse that delivers massive current (±40A) and powers everything from B&W to Magnepan with ease.
This amplifier is cherished for its load tolerance, delivering 200W into 4 ohms and 400W into 2 ohms while maintaining under 0.1% THD. Its high-bias design offers the warmth of Class A up to 50W before switching to efficient Class A/B, making it a rare, original-owner-era gem from the early 1990s that still excels today. At US$1,575, it’s a genuine buying opportunity for enthusiasts seeking a robust, high-current stereo amp without the premium of newer Krell models.

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.
