The Crimson "E" Series Power Amplifiers

Crimson CS640E-III and CS620E-III power amplifiers have an uncanny way of reproducing music with a startling sense of reality and solidity. A way of presenting the recording the way it was intended in its full, dynamic glory.

As with all our products, we design these amplifiers by ear, listening to every single component, every change in circuit design at every step along the way. Our objective is to deliver the impression of real, live musical instruments in your home.

We believe that if we have done our job correctly, you will forget that you are listening to a power amplifier at all.
