"The Elecraft KPA500 amplifier also works efficiently into a load SWR of 1.5:1"

Any such claim is at best misleading.   There may be some 1.5:1 loads that that the KPA500 will be happy with but there are other 1.5:1 loads that it will object to, to the point of giving multiple PA DISS faults.  1.5:1 SWR does not define the load characteristics.   A 1.5:1 load could be pure R or it could be a complex impedance.  The efficiency, PA dissipation, and risk of fault trip are not defined by the SWR.
