Stereo Power Amplifier

Each Evolution amplifier enjoys the hereditary advantage first inherent in the Evolution One amplifier, from faceplate to binding posts.
Realized in monaural, stereo, and three-channel configurations, Krell Evolution amplifiers bring the engaging reproduction of music and movie soundtracks debuted in the flagship Evolution One to a potent new platform.

With virtually unlimited power available, delivered through the most refined circuitry yet conceived, Evolution amplifiers strike the fine balance between pure visceral response and delicate articulation.
Available in silver or black.
