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.

geoffkait - No offense to you personally, gdhal, but you’ve made it abundantly clear you haven’t the slightest idea what “directionality” even means. This conversation can have no porpoise anymore. 🐬 Ta ta!

No offense taken. I didn't think you'd have any kind of answer to my questions. Tell you what though, I'll extend the request to answer my questions (in my 04-13-2018 11:05am post herein) to anyone else who believes as you do.

I've been slowly replacing my cables with low to medium upgrades from the original .50 cent supplied ones and note a significant increase in the  quality of sound. My last purchas of a pair of 18" cables said to give them a 175 hour burn in time. WHAT? Can that really make a difference to the human ear?
Obviously the directional arrows on speaker wire is so you know to reverse them in Australia and  Bizarro world. 
Blah blah blah. Cables make a difference if you can’t hear it you are in the wrong hobby.  You should go be a videophile!
