why do people feel the need to buy expensive cable


I have tried expensive cables and one's moderately priced. I would say there were some differences but I can't actually say the expensive cables were better. IMHO I believe a lot of people buy expensive cables because they don't actual trust their ears and are afraid of making a mistake. They figure the expensive cables are better for the fact they cost more. If you have a difference of opinion or share the same thoughts, I would like to hear about it.

The Amazing Randi offered Michael Fremer $1 Million dollars if he could tell the difference between $20,000 high end cables and Monster Cable. The negotiations bogged down when The Amazing Randi and his team of intrepid pseudo skeptics became a little suspicious that maybe Mr. Fremer might actually be able to hear the difference, even with all the ridiculous stipulations of the Randi Controlled Blind Test.
Clearly, the big fat stiff cables are making up for other deficiences in other areas. 
The negotiations bogged down
Explain please.  What negotiations?  It seems there was an offer by A. Randi so the next step is for Fremer to accept or decline.  Did Fremer ask for best 2 out of 3?  Did A. Randi withdraw the offer?  What are you talking about?  Inquiring minds and all of that....

Because they are scientifically illiterate. People who fall for "audiophile grade" cables (or even worse, for example, "directional fuses") and similar audio trinkets are in the same league with anti vaxxers, flat earthers, lunar landing deniers, GMO panic mongers and 9/11 truthers. A bunch of sad but dangerous fantasists.
Ya gotta love it when someone actually thinks taters is a real person. You can’t make this stuff up folks. Enjoy it while you can.
