I'm not sure your premise is true. It's been a very long time, but AFAIK class A doesn't require more devices, it requires a great deal more heat dissipation. Keep the heat controlled, and you can use the same number of devices.
Your limiting factor is still the rail to rail voltage and the current capability of the devices. That doesn't change going class A, I seem to recall.
However, practical limitations on the effectiveness of heat sinks may be a limiting factor. This is one main reason the early Krell's had built in fans. :)
Best,
Erik
