1990

The KSA-250 (quickly followed by the KSA-150) introduces the innovation auto biasing. It uses robust construction techniques, which are quickly imitated by other companies in the field. A new progressive-start circuit eases the power surge of the mammoth amplifier’s turn-on.

The Krell factory strives to meet continually rising demand without restraining on Dan’s uncompromising standards of quality construction and exhaustive testing. Its dealer base grows with the expansion of the high-end market.

1992

The Krell Audio Standard two-chassis, monaural power amplifier establishes the performance and esthetic standards for power amplifier design. Its fully-regulated power supplies, Sustained Plateau Bias, zero feedback, and remote power switching capability, each an engineering breakthrough in this class of equipment, help make it the world’s premier amplifier design.

1993

Krell introduces the Krell Audio Standard 2 monaural power amplifier and the S-Series of stereo amplifiers: KSA-50S, KSA-100S, KSA-200S, and KSA-300S.

1996

The Full Power Balanced Series of power amplifiers extend Krell’s innovation of Sustained Plateau Bias II and automatic biasing. These power amplifiers deliver Class A operation and massive power output, with perhaps the finest sound quality yet achieved. All three models continue the Krell tradition of fully balanced amplifier design.

The KAV-300i Remote Controlled Integrated Amplifier, the world’s first high-end integrated amplifier.

The Krell Audio + Video Standard Surround Preamp/Processor, the world’s first high-end home theater Preamp/Processor.

The KAV-500 Five Channel Audio Video Amplifier, the first high-end home theater amplifier.

The KPS-20i Integrated Transport and Processor, the award winning CD player/processor by which others are judged.

The Full Power Balanced 250M, 350M, and 650M Monaural Power Amplifiers. These amplifiers expand the Full Power Balanced amplifier category and provide solutions for audiophiles and home theater aficionados who appreciate the performance benefits and system integration that monaural amplification provides. The Full Power Balanced 650M received the prestigious Golden Note award of excellence by The Academy for the Advancement of High-end Audio in 1998.

The KPS 25s Krell Playback System. This integrated component expands on the heritage established by the Krell KPS-20i CD player/processor. The KPS 25s incorporates a reference caliber analog preamplifier, with a professional-grade compact disc transport mechanism and an advanced digital-to-analog converter to provide unmatched sound reproduction from compact discs and other audio sources while providing convenient installation and operation. The disc transport's electronic shutter automatically activates to block stray light from affecting CD playback performance. The KPS 25s Krell Playback System received the prestigious Golden Note award of excellence by The Academy Advancing High Performance Audio & Video in 1998.
