maybe but to run with your example there isnt a whole industry built around marketing expensive beans to stupid people
i guess theres these http://en.wikipedia.org/wiki/Kopi_Luwak and no matter how good it might taste youre still drinking something that came out of an animals arse but the vast majority of coffee (and indeed most other products) wont break your bank and to stick to coffee when you consider it had to be shipped halfway round the globe youll find it has a ridiculously low profit margin compared to audiophile equipment
whereas on the other hand you have audio equipment containing electronics you could pick up for a couple of bucks and solder them together yourself sold for hundreds if not thousands
and even if there were or is a measurable difference in the products it usually bears zero correlation to the pricing
also im fairly certain if you actually took the time to do the measurements youd probably be able to find that for every single component in your audio setup with the possible exception of the speaker enclosures theres a replacement model from china that either contains exactly the same pcbs as the one you bought or causes an either impossble to measure or at least inaudible degradation for a tenths or hundredths of the price
someone also meantioned earlier in this thread that there are apparently people who believe that scratching cds in a certain pattern will make them sound better or that cd demagnetizer which assuming its not a joke product im sure someone out there has spent money on
first of all its clear that you could sell anything to these people no matter how ridiculous and secondly to tie this back into the claim that cds sound worse clearly this highlights that people havent got the faintest idea how any of their audio equipment actually works
to conclude and summarize when buying coffee your observation bias wont cost you hundreds or thousands of euros in stupidity tax
Ohh for christs sake, get that sand out of your vagina already. Insults... pfff! You're the one who called me an idiot if i may remind you.
And we're at the same point again... i would have liked to further discuss the topic, since it's actually an interesting one. But i see you're still in the same old mood of yours, so i'm not even going to bother.
