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.

What i do not get is some members want to just close the door on discussions they feel have been discussed too many times or they do not agree with. What you fail to realize is there are new members joining daily who have yet to state their opinions on topics . It is self centered that you feel since you have voiced your opinion that no others are needed . 
maplegrovemusic, was that for me?

If so, tell me where I've closed the door and just when I said that no one else's opinion matters. In my last post I'm asking for input.

All the best,

From recent posts, it seems like many of the responders are "in the business" of selling audio equipment; that would include relatively expensive cables/wire/interconnects.  I can't help but believe there HAS to be bias in their expressed opinions.
