[Elecraft] KPA500 vs. other amps

[Tony Estep]

This discussion just reiterates the general point that you can't make a pure
price comparison between a differentiated product and one that is not. The
maker of the undifferentiated product will maximize his profits when he
prices it at the marginal cost of production. But the maker of a product
with special desirable features will maximize his profits by pricing it
above the marginal cost of production by an amount that depends on the
perceived extra value, setting the price as high as possible while still
leaving the buyer with some "consumer surplus."
