Just reading through these answers quickly, and toting up the numbers in my head, I've come to the conclusion that 56.375% of the people pay 150% or more for their amp than their speakers. Then there's the 52.325% of people who exceed the cost of their amp with speakers costing in excess of 150%. But of course the extra 12.875% of the people have amp and speakers that each cost below $1000 (together or in combo) where the percentages get screwed up because small differences in numbers have a bigger result. Then there's the 3.25% of modders who can't decide whether to use the original retail price, the retail price plus component costs, or the "equivalent replacement cost" of the modded product.
All this goes to show is that I really don't know how to add, and that audiophiles go both ways (sexy beasts that we are).
Enjoy,
Bob
