I've wondered why there are no amps with external power supplies. Espescially class A, where the heat can get to the caps. There were the Rowland batteries back in the day and the Coda System 100 that seperated the input section. Joule has it's variac. Almost forgot about that Mission/Cyrus optional PS.
Is it just a matter of packaging and financial restraints or is it market and tradition driven, expecting big boxes? Considering the weight and size of some the big amps, perhaps they would be better off in 2 chasis. It could also lead to a modular design and vertical upgrade path.
A while back, I came across some foot square by 4" heat sinks and I seriously considered building some DIY amps with external power supplies and EI trannys. The amplifier boxes would have been one foot cubes, two-thirds of which would have been aluminum fins. Of course, what stopped me is that I have no idea of what I'm doing.
