that component which makes the greatest (positive) difference to the sound of a stereo system is worth the most dollar investment.
aside from the speaker, there is no formula for allocating funds to the other components which makes sense. if one's budget is sufficiently large the task of configuring components is easier than when funds are limited.
unfortunately it is not possible to assemble all combinations of components, so there is an element of luck and the opportunity to listen.
i see no advantage in developing a formula to allocate expenditures on individual components.
