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.
