For buyers, this looks like a fair-to-good buy in a market where the typical used ask sits at US$1,098 and the 25th/75th percentile runs US$882–US$1,333. At US$999, it lands a bit below the median and comfortably inside the main trading range, so it is not a bargain-bin score but it is priced sensibly enough to move on if the unit is clean.
The S300i is well regarded for its punchy, controlled presentation, good bass grip, and a refined-but-not-fussy integrated amp character that suits a lot of real-world systems. If the cosmetic condition is solid and it includes the right remote, it has good upside as a long-lived, high-current amp from a respected era; the main buyer concern is simply verifying full functionality and completeness, since unknown condition matters more at this price than at a steep discount.
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.
