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.

Because in some cases, they sound superior.

In my system, I use a combination of PCs. 2 that were custom made at $175 each and the rest Nordost Valhalla, High Fidelity and Shunyata Sigma.

I build my AUDIO system base on SOUND QUALITY and NOT status, measurements ... I use my EAR and buy what sounds the best!!!
I'm off that particular merry go round. My system has only the very thin wires connecting the lightweight earphones to the portable player. I eschew all other cables, interconnects, power cords, digital cable, what have you.
If the question is about why people have a need to buy expensive cables, then why not ask a more general question? Why the need to buy expensive audio equipment? I don't think there's an actual need, but there is a desire. It may say something about themselves to others, but more importantly it's a self-affirming message to themselves. I deserve it, I can afford it and the world is good! Effectively it's comfort food for the soul.
