This looks like a fair ask, rather than an obvious bargain. At £2,995 for one FPB 250M, the price is defensible for a clean, fully working example, though the UK market is thin enough that condition and provenance matter more than any precise percentile. It would be notably stronger value if this is a recently serviced unit or includes original packaging and documentation.
The attraction is serious current delivery: 250 watts into 8 ohms, 500 into 4, and a design comfortable driving demanding loudspeakers. These are powerful, transparent, fast-sounding amplifiers with the authority and scale associated with classic Krell, while the non-CAST 250M version can be particularly appealing when used with conventional balanced or single-ended equipment. At this money, confirm quiet operation, healthy bias and regulator indicators, clean relays, and sensible heat behaviour; a demonstration into your speakers is well worth arranging.
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.
