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.

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.  

Who gives a flying fig!  Buy what you want and enjoy.  Don’t be jealous if someone’s cables are bigger, longer and thicker than yours 😉

Geoff is definitely more than a few cards short of a deck 😝. He’s also wrong...a rich man can buy his audio indulgences over and over again until he accidentally enters Audio Nirvana!  A poor man has fewer options and needs to get it right the first time...IOW, the deck is stacked against him or her or it or whatever is PC today.  Of course Geoff would convince the poor guy his Bose would sound SOTA if only he would buy some of his audio trinkets and snake oil.  Actually, that makes Geoff worse than a rich man.  At least a rich man wants to have an honest chance at purchasing a slice of ANirvana, while Geoff lives off the poor, desperate wretches looking for a magic potion to convert their electronic grunge generators into heavenly sonic bliss!  I can respect the rich man for his capitalistic purity.  Geoff however, is far worse...for he sells empty dreams.  Then again, perhaps that defines a free society afterall.  Anyone should be able to pursue anything they want, no matter how foolish or baseless it may be.  Carry on dear patriot...let not your conscience be bothered.
