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. These four new models utilize Active Cascode
Topology, a unique circuit technique that minimizes distortion by applying from 2
to 3 times more active devices to each gain stage. Evolution Series amplifiers
bring the real-life dynamics and transparency for which Krell is famous, to a whole
new level.
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
