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.

Yup there are those who enjoy the information and the banter. Any way I have been testing a loom of atlas mavros. They are pretty good. They are from Scotland. They do a really good job sound wise. They see to work better with speaker cables and interconnect both implemented. Pretty pricey but they sound a lot better than the Audioquest Rocket 44 I had back in the day. 
I have spent way to much money chasing audiophile heaven with all types of cable designs and materials...my myopic conclusion is that MIT DELIVERS THE GOODS! Now if you have owned as many cables as I have and compared them to MIT in your system, you may come to a different conclusion. My experience, which is substantial, confirmed to me that only a cable system that actually addresses the issues surrounding signal transfer can actually give you real results and not just tonal abberations and frequency variations, which may or may not please your ear subjectively.
I have no doubt whatsoever with your findings, it's just the tone.

I actually wish I could afford to try the expensive cables out there. I don't begrudge anyone who can. My point is that there are not two camps here decrying each other nor the need to put the wagons in a circle.

All the best,

@Dave, I'm glad you found good synergy in your system with MIT cables. They are very good. Just curious if you auditioned Swedish Jorma cables?
