Evolution Series amplifiers continue the quest to 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 are shared throughout the Evolution Series amplifiers.
