This is a class-D thread. No one is pushing anything. I am stating, quite clearly, that your "push" of EPDR as a relevant value is meaningless w.r.t. Class-D amplifiers. Given that EPDR is meaningless, we don't need to consider 0.9 ohm loading as you have pushed for the Alexia as it has not meaning within a Class-D discussion. The standard impedance which does not dip below about 2.5-2.6 ohms, is the relevant value for discussion.
BJT has nothing to do with a Class-D discussion, but since you bring up EPDR, EPDR is most damaging to a BJT amplifier in real world conditions because of secondary failure that MOSFETS, and tubes do not experience.
