What of your gross annual income is your system?

It's the old case of my eyes & ears wanting more than the wallet will permit. . . I realize that to the degree that music is important in your life will influence your spending on system components, tweaks and music. What % of your annual gross income would you say your system is worth? Moreover, how have you allocated your system investment (as a %) to amp, pre-amp, speakers, wires, source etc.? THanks for your input.
