krell audio standard

I do not think the standard audio krell kas and 2 are in pure Class A but rather slippery in Class

FYI, for KAS, the manufacture recommendation is 30A per mono.

Both KAS and KAS2 abilities to drive 1ohm or perhaps lower are still matched only by very few amps. They are pure class A hence runs very warm as space heaters, yet have that musical hearty class A sound. Being a KAS2 owner, I would STRONGLY recommend giving each mono a dedicated 20A line. Quite a few ill sounding Krell's I have heard suffered from outlet power/current starvation. Give your Krell's sufficient juice, and you will be rewarded correspondingly. Just my 2 cents and good luck!

The are the most musical amps Krell has ever made with endless current to drive any speakers. The KAS-2 are smaller version without the full size power supply and 50% less power.
