Yeah, good stuff should cost a lot, no objection from me. If someone claims that his $5k one 8" driver can do what others cannot, I'll say okay let's hear it.
As an example of something completely different, I just bought $400 5.5" custom knife mostly for the kitchen, though it can be used for many things. And you know what, it's a big bargain, it cuts thru everything like hell and edge holding is incredible. The man who made it is considered to be on top five list of American bladesmiths.
Great speakers should cost at least $25k or so, I would think. That's the reason why I am not thinking for now to upgrade what I have. I would need about $10k to get a great used pair, anything less would give me some improvement but no satisfaction.
