At US$1,349, this sits right on the median of your recent comp set, so it reads as fair market rather than a bargain or an ask that needs pushback. With the 25th percentile at US$1,225 and the 75th at US$1,392, the number is firmly in the normal trading band for this amp.
That makes sense for a Krell piece like this: the KAV-400xi is well-liked for its grip, drive, and muscular, clean presentation, with enough current delivery to make tough speakers wake up. A clean, complete unit can be a very satisfying buy if you want solid-state authority without moving into truly exotic pricing; I’d mainly want to confirm provenance, remote, and that it powers quietly and runs cool, since age and service history matter more than cosmetic perfection at this level.
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.
