We are now building in our Connecticut factory a new type of amplifier with musicality that surpasses that of Class A and the energy-efficiency of newer Class G and H designs. Our iBias designs deliver all of this in a surprisingly compact package – and it also incorporates Internet-based technology that will amaze both audiophiles and systems integrators. The new line includes seven mode...[more]

This design gives the Krell amplifiers lower internal impedance, which allows firmer, more precise control of your speakers. Krell CAST Circuitry delivers the purest signal when connected to Krell CAST equipped preamplifiers. Power Supply Highlights One 750VA toroidal transformer feeds amplifier modules that include the audio circuitry, rectifier, and power supply filtering mounted to an indivi...[more]

Circuitry Highlights Patent pending Krell iBias Class A technology allows our latest amplifiers to run in full Class A mode to full power while minimizing heat generation. All signal gain is realized in the current domain using discrete, proprietary, multiple-output current mirrors with extraordinary open loop linearity. There are no generic integrated circuits or op amps used anywhere. Current...[more]

From decoding the latest lossless audio formats, extensive digital switching, 3DTV pass-through, and more, the Foundation is fully compliant with the digital age. Yet the 7.1-channel processor also features balanced audio outputs, automatic setup and room EQ, and Krell’s legendary robust hardware. A slim new form factor exudes the Krell aesthetic, while allowing placement in smaller equip...[more]

The Krell Illusion preamplifier is a dual monaural circuit design with the left and right channels afforded their own power supply regulation and individual full chassis sized boards. All signal gain is realized in surface mount topology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. 1.5 MHz open loop bandwidth in a zero feedbac...[more]

Circuitry Highlights: the Illusion II preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero fee...[more]

Krell Industries has earned a distinguished reputation over the past 30-plus years for engineering innovation and product excellence. In 1999, the Krell engineering team headed up by Dave Goodman released the original KAV-300i integrated amplifier which stunned the world. At the time and conceptually, the original KAV-300i was the world’s first high-end integrated amplifier that delivered...[more]

All signal gain is realized in the current domain using discrete, proprietary, multiple-output current mirrors with extraordinary open loop linearity. There are no generic integrated circuits or op amps used anywhere. Current mirrors in the final gain stages use a new output power device that operates at a 73% higher voltage, delivers almost 10% more current, and offers 120 watts of additional ...[more]
