• Expandable Digital Path: Optional module adds network streaming, HDMI and high-resolution DAC performance.
Audition the Krell K-300i at our Lane Cove showroom to hear its combination of power, control and refined musicality.
With frequency response extending well beyond the audible band and vanishingly low distortion at full power, the K-300i presents music with scale, grip and composure.
The dedicated preamp regulation, precision volume architecture and Current Mode circuitry keep the signal path clean, while the substantial analogue output stage delivers the slam and low-level resolution Krell is known for.
Whether used as a purely analogue integrated or with the optional digital/streaming module, the Krell K-300i is a compelling centrepiece for a serious stereo system. Its 23.6 kg chassis and generous heatsinking reflect the engineering needed to deliver sustained high-current performance in everyday use.
Technical Specifications

A used Krell K-300i at A$6,900 sits just above the A$6,593 median and well below the A$8,062 75th percentile, so this reads as a fair-to-slightly-strong asking price rather than a bargain. It is not cheap, but it is still inside normal market territory for a serious integrated amp of this class.
The K-300i is well regarded for grip, authority, and a very controlled, spacious presentation, with enough current delivery to make demanding speakers wake up. If the listing is clean and complete, the value is in buying a heavyweight modern Krell without paying top-of-market money; at this level, original accessories, service history, and confirmed working condition matter, but there’s no obvious red flag from price alone.
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.
