I recently visited a Pass dealer, who explained that Pass amps are more alike than different, but are rated differently. IOW, the class A amps do indeed cross over to Class B beyond their rated class A power. A Pass class A model rated at 100 watts/channel will deliver, perhaps, 300 watts, but in class B. The rating merely tells you how many class A watts you'll get, not the amp's peak output capability. I'd speak with a Pass dealer or even Nelson himself before you decide.
