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.

Maybe when people get to a certain point the feeling is the only way to move forward is to spend more.  

Also so remember that no change in sound is better than a real one if the real one is for the worse.  

no doubt one cannot take the human factors out of the equation.  If a hifi plays and there is no one to hear it what does it sound like?  🤔
...the best cable is the cable that changes the signal the least.
I couldn't agree more. So it goes to say that despite protests to the contrary, all cables are not made the same and there are makes that get it right or better than most and it's all system dependent.

Lots of variables here, so in the end, it's your ears that decide what sounds best in your system and to offer advice on what works in your system shouldn't come under fire from others who don't know or appreciate the particulars.

All the best,

Many of us can agree that cables do indeed make a difference but the point of the thread was about expensive cables. I took this as a shot on manufacturers that hyper inflate the cost/performance ratio. 

Has anyone ever done or know of any info on a part cost analysis of any major brand cable makers ? I have seen breakdown of other gear before in professional reviews.

Manufacturing costs can be figured out for most consumer products made and sold .

Why the mystery for audiophile cables i ask ? Please enlighten me .
