Why so expensive??

I'm siting here Looking at amps,preamps,speakers,etc...and wondering why some of this stuff cost so much.Don't get me wrong i have some crazy expensive equipment,but $350,000 for amps' come on give me a break.$100,000 for a pre-amp'please.There is no way in h#%* it cost even close to that for parts and build time.So why???What NUT whould buy something like this?Ohh it's the same Nut that just traded in his '06 lamborgini for a '08.God bless you folks with that kinda of cash.And by the way when your ready to trade up let me know i will take your used equipment for FREE since you blowing your money anyway.
Thanks in advanced for your used equipment..
