That is exactly why it's important that the ATU of a solid state
amplifier maintain a low SWR.

There IS a reason to be fanatical about a 1:1 SWR, although it doesn't
apply to an amp like the KPA1500.
If you are running a tube amplifier that requires tuning, and the
tuner always provides the identical load, you can tune the amplifier
once, record the dial settings, and quickly reset the amplifier tuning
"by the numbers" when you change bands.
But even a small change in load impedance might require manual
touch-up of the amp tuning. So it is nice to be able to preset the
tuner exactly.
