Mitch4t,
As Gs5556 and Marakanetz have pointed out; the amplifier
class has nothing to do with whether the amp doubles its
power as the impedance is halved.
The doubling is a function of what the power supply and
output stage are capable of. You can have a Class A amp
that does not double - and you can have a Class A/B amp
that does double.
However, you may still see more Class A amps that double
than Class A/B. It's not a function of the amplifier
Class - but due to the fact that a manufacturer that takes
the philosophy of going Class A - accepting the down-side
of extra heat generation, etc in order to gain the
advantages of a Class A - might also provide the beefier
power supply and output stages needed to power double.
Class A and power doubling are not "cause and effect" - but
rather are both hallmarks of a design philosophy.
