With the Krell FPB 700cx, I can say with certainty that we have an amplifier that should find itself a permanent home in all but the most obsessive, tweaky and ultra-deep pocketed audiophile.
This is a proper serious amplifier and the asking price looks fair to very slightly soft against your local market data. With a median of £5,990 and a 25th–75th band of £5,522–£6,001, this listing lands exactly on the median, so it is priced right in the sweet spot rather than pushing into bargain territory.
What makes it worthwhile is the Krell name: the FPB 600 is one of those muscular, high-current stereo amps that earns its reputation on control, grip, and scale, especially with speakers that like real authority. In excellent condition, this is the kind of buy that can make sense if you want endgame-grade power without paying fresh-stock money. At this price, the main upside is simple: if the presentation is as clean as stated and it has been well cared for, it’s a confident buy for someone who knows they need the drive and build quality.
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.
