Krell Industries Evolution 600 - Manual (Page 5)

A Letter from Dan D’Agostino
Dear Audio Enthusiast,
Thank you for your purchase of a Krell Evolution Series amplifier.
Evolution Series amplifiers continue my quest for amplifiers that deliver absolute
truth in music reproduction. Active Cascode Topology is a unique circuit technique
that minimizes distortion by applying from 2 to 3 times more active devices to
each gain stage. The attributes of this topology is shared throughout the Evolution
Series amplifiers.
Krell amplifiers are best known for their ability to drive any loudspeaker to sound
its best, without regard to impedance or efficiency. I believe that linearity, an
amplifier’s ability to output an exact duplicate of the input signal, is the ultimate
measure of that amplifier’s work. At Krell, I drive amplifier designs toward the com-
mon goal of linearity, through the rigorous application of Krell design principles
that focus our efforts on four major performance factors: distortion, bandwidth,
output impedance, and current capability. The Evolution Series amplifiers are a
synthesis of these factors.
The Evolution Series amplifiers use Evolution CAST technology, for superior per-
formance and very low noise.
I hope that you enjoy your new Evolution Series amplifier.
Sincerely,
Daniel D’Agostino
Chief Executive Officer
