All Evolution amplifiers feature massive power supplies with the Evolution 402 and Evolution 600 equipped with a 5000 VA power supply and the Evolution 403 and Evolution 900 housing 6000 VA power supplies.
The Evolution Series continues to expand, and now offers five powerful amplifier models. Stereo components include the new Evolution 302 as well as the Evolution 402 amplifier. The Evolution 403 is a three-channel amplifier and the Evolution 600 and 900 are monaural amplifiers. Two monaural amplifiers are required for stereo operation.
FEATURES:Active Cascode Topology eliminates global negative feedback, only nested local feedback is employed around individual gain blocks. The result is an extraordinarily open, liquid, effortless sound.
The signal path incorporates Krell Current Mode and CAST circuitry using proprietary multiple-output current mirrors in a complementary and balanced arrangement for extraordinary open loop linearity.
Evolution circuit topology breaks through bandwidth limitations of conventional designs resulting in near perfect performance in the audible range.
The power supply makes use of extensive electrical and magnetic shielding to keep radiated interference out of critical amplifier circuits. Internal high current line conditioning circuitry filters RF noise on the AC mains, as well as compensating for asymmetric power waveforms and DC on the mains.
The rails powering the amplifiers' low level and gain stages are regulated twice for total immunity from fluctuations in the AC mains and virtually noise-free output. Advanced microprocessor control monitors critical operational parameters.
