I haven't measured IMD on my KPA500 either since I don't own two generators that
are clean enough with the necessary power to do so.
I would suspect, however, that the amp is cleaner that a K3(S) driving it.

As to running the amp at 500 watts, or 600 watts or 700 watts, thus just
before fault power, I would need to examine the IMD products to be confident
the amp is "clean". A solid state amp which is being over driven just a wee
bit can get really nasty on the air and real fast. The product is splatter on
either side of the operating frequency. Avoid this and sacrifice a few watts
of output power.
As to the KPA1500, I have no experience or knowledge. But I would say it
follows the same rational of operating and efficiency.
