The Evolution Series culminates more than two decades of cutting edge
audio design. When envisioning Evolution, Krell had one solitary goal -“ to
hand craft a preamplifi
er and power amplifi er that, simply put, were the
best sounding products ever built. The result is a synthesis of almost
impossible contradictions; a unique blend of beauty, grace, and the
effortless power synonymous with the Krell name.
Evolution One Amplifi er
The Evolution One is a Class A, 450-watt monaural amplifi er that utilizes proprietary current gain topologies from input
to output allowing the audio signal to remain in the current domain throughout the entire amplifi er thereby avoiding
unnecessary current to voltage conversions that add distortion, require heavy feedback and severely limit bandwidth.
The Evolution One circuitry is virtually devoid of feedback and sports a bandwidth an order of magnitude greater
than any conventional design. Coupled to this circuitry is a power section that is virtually limitless in its capability to
drive any speaker to its full potential. With all of this unrestricted power on tap, the Evolution One employs advanced
microprocessors that constantly monitor operating conditions and can automatically adjust the operating parameters
or shut the amplifi er down to prevent damage to the input stages or loudspeakers. $50,000
Evolution Two Preamplifi er
The Evolution Two monaural preamplifi er is a Class A design that was built to absolute perfection inside and out. The
audio signal path operates in full balanced mode from input to output and the proprietary Krell CAST inputs further
ensure absolute integrity of the audio signal. Nothing was overlooked when designing the Evolution Two; not even the
volume control that features a 16-bit balanced resistor ladder which uses low-resistance, high-linearity solid-state
switches and discrete precision resistors for the purest line stage possible. Although the Evolution Two embraces the
simplistic pleasures of a high-end two channel preamp, it also features sophisticated RS-232, IR and 12-volt controls
for better integration into a state-of-the-art home environment. $40,000
Ferrari and Cartier say you enjoy luxury and know quality.
Krell says you never compromise.
