The Krell Legacy
“I design every Krell component to set the standard
for workmanship, style, and performance.”
Dan D’Agostino
High-end audio is a demanding pursuit—an ongoing quest for excellence in
music reproduction that drives equipment manufacturers to strive for the absolute
in design and performance. With a keen understanding of this passionate drive,
Krell Industries, Inc., was founded in 1980.
Over the past 2-1/2 decades, Krell has earned a distinguished reputation for engi-
neering innovation and product excellence. The company’s history is replete with
product introductions that have deeply impacted the high-end audio industry.
The most discriminating audiophiles and product reviewers have consistently
recognized Krell components for standard-setting performance.
The Evolution One amplifier brings Krell design to a new level, setting a standard for
performance that will not soon be matched. The shear breadth of this amplifier’s
dynamic range capabilities conveys a startling realism that transcends previous
designs. Seemingly unlimited frequency response, combined with unerring accu-
racy and fortitude, extend a tradition that began with the first Krell amplifier — the
KSA-100.
The KSA–100 was the first high-power, high-current, true Class A biased stereo
power amplifier available to audiophiles. It was the first Krell product, and its
resounding success established Krell as an important new technological contrib-
utor to high-end audio.
