Technology
Active Cascode Topology
A unique circuit technique that minimizes distortion by applying from 2 to 3 times
more active devices to each gain stage thereby reducing the load on individual
devices and improving circuit-wide linearity.
Krell Current Mode
A proprietary Krell circuit topology in which the audio gain stages of a component
operate in the current domain rather than the voltage domain. This unique technol-
ogy provides the component with exceptional speed, and a wide bandwidth.
