When new, the Krell S-300i sold for roughly US$2,500, so US$950 is a strong used-market price. It lands exactly at the median of the three recent comparables, but remains comfortably below the US$975 75th percentile and well above the US$740 25th-percentile bargain threshold. In other words, fair rather than a steal—but certainly not overpriced.
The appeal is serious power in a relatively compact integrated: about 150 watts per channel into 8 ohms, with the current capability to reach roughly 300 watts into 4 ohms. Its substantial transformer, balanced input, solid preamp section, home-theater bypass, and useful control connectivity make it a versatile partner for demanding speakers. At this price, a complete, fully functioning unit with its remote and original accessories is worth pursuing; verify display, remote operation, input switching, and that it runs hot but normally.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
