The Evolution 600e is equipped 2 2,200 VA transformers and 108,000 microF. This power source is the backbone for the output of the Evolution 600e. With this foundation, the Evolution 600e delivers 600 watts into 8 Ohms, 1,200 watts into 4 Ohms, and 2,400 watts into 2 Ohms. The FTC mandates that power ratings are quoted using a 1,000 Hz sine wave into a fixed 8 Ohm resistor with final power specification stated at 1% distortion. Krell engineering considers this specification too lenient and not indicative of what an amplifier is required to provide. Krell designs to a much stricter standard. Our power tests use a 20-20,000Hz signal into 8, 4, and 2 Ohm loads with our final specifications stated for .1% distortion.
