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 thr
oughout the Evolution
Series amplifiers.
Krell amplifiers ar
e 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
measur
e 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-
for
mance and ver
y low noise.
I hope that you enjoy your new Evolution Series amplifier.
Sincerely,
Daniel D’Agostino
