The KSA-150 is rated as delivering 150 watts per channel into 8 ohms. The amount of Class A power is adjusted for the finest sonic performance with a minimum of generated heat and energy consumption. The amplifier’s maximum power into 8 ohms is 220 watts per channel. The KSA-250 is rated as delivering 250 watts per channel into 8 ohms. The amplifier’s maximum power into 8 ohms is 320 watts per channel.

That every Krell product uses Class A circuitry in all gain and supply stages is a foundation of our design philosophy. A second design commitment that relates to amplifiers is that every unit be capable of doubling its output into successively lower impedances. The KSA-150 will deliver 300 watts per channel into 4 ohms, 600 watts per channel into 2 ohms and 1,200 watts per channel into 1 ohm. The KSA-150 is fully capable of driving impedances below 1 ohm. The KSA-250 will deliver 500 watts per channel into 4 ohms, 1,000 watts per channel into 2 ohms and 2,000 watts per channel into 1 ohm. The KSA-250 is capable of driving impedances below 1 ohm.
