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.

Price means next to nothing, I look at it in categories because one companies mid range may cost more than another company's extreme product, and the cheaper one may blow that away because their extreme costs over $20,000.

So how about this more pertinent approach?
mid range
high end performer
ultra ridiculous, but appropriate for certain systems

Many companies that make a great range of the three haven't managed to create an ultra cable, and some of those are out into 40 and 50 grand.

Transparent, MIT, Nordost, Audioquest, Kimber, all make mid ranges from $1500 to a few thousand dollars, while there are companies making their top cable that blows them away for under $1000.
Tonykay, that would be nice if I did, unfortunately I do not, however, I can certainly hear a difference between every model, no matter the cost.
