$20k is a magic number since it *CAN* be attainable for a lot of folks. $308/4weeks is $4k/yr. That's a major component purchase each year right there! In four or five years you'll have your $20k (or thereabouts) system.
As to milkman's observation of the $20k barrier - I think to a lot of folks the $20k barrier is pretty psychological. Much in the same way a $1k or $2k would seem to a non-audiophile. One $20k seems to buy a whole lot of performance without loosing everything completely to diminishing returns. And two it's a nice round number. But good observation milkman. But normally I would guess the ranges to be $10k and $40k. That's what I think I see.
