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.

There are volumes of research on why people buy luxury goods. High end audio is a luxury item and within high end audio expensive cables are even more of a luxury. The literature is pretty clear on a consensus view. Buying a luxury item makes someone feel good about themselves. Whether or not the cables out perform lesser priced cables is somewhat besides the point as long as the buyer perceives them as a good value. Whether or not someone else considers the purchase to be a good value is also besides the point. In some cases, external criticism of the purchases reinforces the purchaser's positive feelings.
By and large, according to many reviews and many comments by individuals, and regardless of whatever silly arguments naysayers might come up with, the more expensive cables are the best sounding cables. That is not to say that the most expensive cables on Earth are the best sounding ones, necessarily, but they should get you into the ballpark. By the same token, if you purchase some High Fidelity cables they should At the very least get you on the ball park. Of someone is sporting some $105,000 Rockport Hyperion speakers and a $102,000 Walker Audio turntable what's the harm in say $20,000 worth of cables? I don't begrudge anyone buying a $205,000 Ferrari California. Live and let die, I say.
The difference in performance between a $205000 Ferrari and an every man's Toyota is pretty clear.

The difference in performance between various wires is often not so clear. Other than price.

That's the difference.

I agree people can and should feel good about buying whatever they want. If they are happy in the end, all is well.

So its a reasonable answer to say the reason they do it is to make themselves happy, whatever the cost.

Audiophiles are notoriously hard to please when it comes to the toys they love most.

So there you go.

The merits of one cable versus another and the value proposition is a much different and more complicated story.

So there you go.

An easy path and a harder one.....
"Like i have stated before the price of copper is $5 a pound . So , it is not the price of the copper . What's left ? Only referring to copper cables as they are the most popular ."

Sorry. I thought you were speaking English. I should have known that a direct answer to a direct question wouldn't go over all that well. So what type of answer were you looking for, if not a direct one? If you can't come up with anything, we'll understand.
