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.

Get the best sounding stereo you can afford. It's perhaps one of the saner things you can do with your money. Get the best (read most comfortable, sleep inducing) bed you can afford. Give as much as you can to those organizations that promote the most public and environmental welfare.Treat yourself and other to the good things in life.
 Who knows how much longer we have? Enjoy it while it, you last.
I spent over $3000 on some AC duplex (for the stereo of course). Most recent spent $100 for four resistors which happened to be on sale for 50% off.                   
So just how much SHOULD I be spending for interconnects? (naturally this is a rhetorical question, but I am sure I can get some answers... FYI my last two IC spending sprees cost me $9000.)
A rich man has about as much chance of entering audio Nirvana as a donkey has of passing through the eye of a needle. 

No mater what side of the fence your on with cables looks has something to do with it as well.

 why would I want some ugly lamp cord between your amps and speakers specially if you have substantial money invested.

regardless of how good something sounds if the component is homely to look at it will generally not stay long. Beauty is of course the eye of the beholder.  

 Likened to plain steel wheels on a Ferrari yeah they work but really don't look the part.
