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.

It's funny reading these responses. Just what the OP wanted. Stir them up, start them quarreling.
just for clarification, I don't use the $42k Tara Grandmaster speaker cables that Audiolabyrinth refers to here;

.....Mikelavigne's Grandmaster original model speaker cable's retail for 42,000.00 8ft, his system may be better for such cable's......

my speaker cables are Evolution Acoustics TRSC (Triple Run Speaker Cables) which are the best speaker cables I have heard. approximately $8-9k for an 8 foot pair. not cheap but not crazy. the one step down model of the Evolution Acoustics speaker cables (double run) replaced Transparent Audio Opus MM speaker cables ($34k) in my system. then i upgraded to the EA TRSC i now use. I'm very happy with what i hear from those speaker cables.

for me the price is not the issue. it is performance.

what I do use now is the Tara Labs Grandmaster Evolution 1.5m XLR with the HFX which does list for $31k. i bought it used and got a great deal. and what it did rocked my world enough that i ordered another set of the same cables new but in a 2 meter RCA length. it lists for approximately that same $31k. it should arrive this next week. i would never have even thought about buying those if i had not heard with they did in my system. it's astonishing and they will screw your head up if you listen to them, they are that good.

10 years ago i had Von Schweikert VR9SE speakers and vertically bi-amped them using 2 sets of Transparent Audio Opus MM speaker cables. that was 2 x $34k list price at that time. it sounded amazing.
Mitch2,
your observation is again another proof that most of money paid for luxury and looks just like Prada or Luxotica.
The value is still somewhere in $50 range.
