[citation][nom]wortwortwort[/nom]The current design of the Big O has you paying $7799 (Yep) ...That comes to a total of $3605.
From this estimate, it would seem that they charge 116% to assemble it. That is ridiculous in the extreme.[/citation]While I have no interest in such an expensive system, you need to look at other factors. You aren't just paying for them to assemble components. They have to be compensated for their time researching components, compatibility, benchtesting, offering a warranty/support, advertising, payroll, and everything else that goes into running a business.
Same philosophy applies to pretty much any manufacturing process. Do you really think it costs $250K in "materials only" to build an exotic sports or luxury car? Of course not. You're also paying for all the R&D that went in to the product. And, yes, for some exclusivity. And then on top of all that, no one runs a business to "break even", so there's the markup so they can make a profit. No profit = No business. No business = No product.
What I listed are just a few of the things (re: "overhead") that the home enthusiast doesn't have to contend with.
