These are very rare; 2 versions - KAS-1 and KAS-2. They were the first Krell amps to use the Auto-Bias circuit and could drive anything, including Apogees.
The KAS series amps, to me, sound much better than their current line. The current line of Krell amps are not as tough as they used to be, because the trend in speakers these days in high impedance and easier to drive (ie, Avantgard Horn vs Apogee ribbons).
