Right now this is clearly a buyer’s market for this category: at US$775, this is far below the US$1,319 25th percentile and well under the US$1,550 median, so it reads as a strong deal rather than a merely fair price. For a stout Krell stereo amp, that’s the sort of gap that usually gets enthusiasts’ attention fast.
The KAV-250a is respected for clean, authoritative current delivery, big dynamic swing, and that effortless grip on real loudspeakers that made Krell a reference name. If the unit is clean, stable, and truly working as it should, the upside is excellent. At this price, the main buyer focus is straightforward: confirm no channel imbalance, protection issues, or obvious service history concerns, and make sure it’s being sold as a complete, honest working amp rather than a problem hiding in plain sight.
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.
