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.

This sums up my whole point . He was a stranger i had just met . Why would i feel the need to tell him what cables he should be using ? Same goes here on the forum with your my opinion of what cables need to be used to get great sound . 
if you are referring to me kjanki you are mislead . I hear a sound signature in all cables that have been in my system . Not much more to say on that topic . Next statement please 
I'm NOT telling anyone, one must spend X amount to get a good sound.   Like I said, I think most members are just sharing their experiences.  It's your money so do as you wish.  Why do I care?
Exactly , Who cares ? i sure do not . Some others wish everyone would spend more money on cables for some reason . Are they affiliated or making money some how ? If it is a livelihood i understand the fever determination to have that stance . Otherwise it is just the get what i have mentality . 
Here is a way to explain the overpriced cables : Take and compare a $5000 amplifier with a $5000 cable . Lets take a close look at the materials and costs to build both . Amplifier - God knows how many actual parts ? Think of the labor involved in making it . Now look at the cable . You have a handful of materials to assemble . How many companies smelt and extrude the wire themselves ? If they outsource this they are paying materials and a hour of assembly , packaging .. ect
