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.

It's all quite simple realy.  Would you take you 10 K McIntosh power amp and strap it with some 16g zip cord to your 20 K Martin Logan sound producers, I THINK NOT!  And on the flip side would you strap your 50.00 Radio Shack'y music box to your 10.00 bookshelf yard sale bonanza speakers with 1 K  audio cables,  NOT REALY!

Point being, match your dollars and system with the best cable that you feel good about, and let the sound carry you away.
I set a maximum amount to spend on cables, but am always happy to spend less...I would never say you need to spend x to get good sound...but I also find the best sound rarely comes cheaply...
I just went to hear some $15,000 PBN speakers this weekend at a fellow audiophile's house this . The wires he was using were ten dollars a foot . Needless to say the sound was superb .
I don't set a predetermine budget on anything and buy what sounds best to my ear.    My neighbor has $150K full loom of Stage 3 cables.    I respect his decision.   He's successful, earned the money and happy with the results.  Who am I or anyone to criticize his decision.

I don't find any member suggesting one has to spend x amount of dollars but just recommending different products.  Some happens to be expensive.
I'm  sure they did, great speakers...did you have a chance to compare cables on them?
