At the International CES Expo in Las Vegas, Krell introduced the most revolutionary design change in its 33-year history: iBias™, a patent-pending new technology that uses the Class A circuitry preferred by audiophiles yet consumes far less energy than a traditional Class A amplifier does. Because iBias technology eliminates crossover distortion, it allows the low-level details, subtletie...[more]

The integrated amplifier CSA29 combines the benefits of both valves and transistor amplification using the synergic design concept that has made Copland hybrid amplifiers widely acclaimed.The amplifier uses two valves in the input differential stage, allowing the notably smooth and transparent properties of the valves to blend with the power and dynamics of the transistor electronics.  The am...[more]

The Definition Series of amplifiers represents an unusual type of "solid-state hybrid" design in which a massive, highly regulated, linear analog power supply is combined with a truly "green" discrete analog switching-MOSFET output stage for highly efficient power conversion and low power consumption. The analog power supply and all-discrete MOSFET output stage are pure Audio Research expressions ...[more]

The Fully Balanced Integrated Amplifier (FBI) is a large-format integrated amplifier that offers all the power and control afforded by big Krell amplifiers in a convenient, integrated package that is simple to operate. A new Current Mode preamplifier topology features an Evolution CAST input for pristine signal integrity. A balanced, 300 watt/channel amplifier delivers the dynamic contrasts for...[more]

The KAV-300iL Integrated Amplifier provides essential power and control for audiophile music systems. It offers a high level of sound quality, with a smoothness and surety of operation matched by few other components at any price.The KAV-300iL is an ideal component for audiophiles who hold quality, performance, and convenience as their highest goals. Highlights Maximum power output of 200 Wat...[more]

The Krell KAV-400xi is a high performance integrated amplifier that combines the hallmarks of Krell engineering design-Class A amplification, balanced circuitry, unique technology, Krell build quality, and impeccable sonic performance into one, beautifully styled component. Sonically, the KAV-400xi features a prodigious bass response, an open, natural sounding midrange, and highs that are extended...[more]

AUDIOPHILE GRADE INTEGRATED AMPLIFIER Employing a massive 750 VA toroidal transformer and 38,000 microfarads of capacitance, the S-300i sets the performance standard for integrated amplifiers. At 150 Watts per channel into 8 Ohms and 300 Watts per channel into 4 Ohms the S-300i is built to meet the demands of today's latest loudspeaker technology. A KRELL Class A, direct coupled design, ful...[more]

It was all a bit of shock back in the ‘90s when Krell suddenly introduced a neat little integrated amplifier in the form of the KAV-300i - such a contrast to their tradition of big, beefy power amps. But once past the scepticism we all realised, perhaps to our surprise, that this slim and unassuming device actually had a good measure of Krell’s unique signature: control, dynamics an...[more]

The Vanguard’s amplifier incorporates a massive power supply with a 750 VA toroidal transformer and 80,000 microfarads of storage capacitance. The tremendous amount of energy on tap provides 200 watts per channel into 8 ohms and 400 watts into 4 ohms. Two quiet, thermostatically controlled fans permit the use of a surprisingly compact chassis. The preamplifier section of the Vanguard ...[more]

The Digital Vanguard incorporates a 200-watt-per channel amplifier and a Class A preamplifier, enclosed in a chassis that borrows its design and construction from the new Krell Foundation preamp/processor, Connect stream player, Illusion preamp and iBias amplifiers. Digital support has been included with USB, HDMI, coaxial, and optical inputs as well as Ethernet audio and Bluetooth streaming. ...[more]
