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.

....and even had your fraudulent representations deleted by the forums thoughtful and purposeful moderator's....

I do recall a number of your threads were also deleted.

As to fraudulence, I look at a bit differently. As soon as I mentioned my rationale for wanting to skype - because seeing and hearing you lends credibility to the authenticity of your interest - and that it is a  possibility you are merely a 14 year old school girl without the financial means and/or legal authority to enter into any agreement - did I validate your insincerity. 
I have a higher end sound system (McIntosh and Revel Salon 2's). I had a bunch of friends come over and they all brought various speaker cables. High priced down to cheap junk. Fairly scientific, no beer until the test was complete. We did blind testing. We really embarrassed ourselves. A dozen cables from $50 to $1000 and we were all over the board. All I'm saying is perhaps you should test several cables prior to purchasing. You may be surprised at what you don't hear.
Love to spend 10k on cables because they sound way cool.

They sound even cooler once you've reversed their direction.
