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.

Thanks gdhal I get so tired of folks acting like it’s just our imagination 
Hey guys what are some good brand name cables, that look nice that I can get to elevate my system to the next level? I currently use stock power cords, blue jeans speaker cables, and $5 interconnects (ugreen off amazon, $10/pair) the only slightly "audiophile" cable I have is a $40 coax cable I purchased from dysonaudio.com 

i was looking at nordost and Coincident for speaker cables, furutech for power cords however I don't want to spend more than $2k total. I was thinking I could save a massive buck by buying used but I'm scared of getting ripped off by buying fakes. 

My system is all balanced, pass labs amp/pre, balanced dac, mostly listen to music over USB and coax on my pc / CD player.  Speakers are Harbeth 30.2. 

As ive never seriously put much thought into this until now I'm at a bit of a loss.

also for the record I did not enjoy audioquest rocket 44, I thought it actually sounded worse than my blue jeans cables, I think something to do with the use of silver in the conductive path?
Consider Signal Cable d2girls!  Very good stuff and extremely inexpensive for the quality.
d2girls, for balanced analog interconnects I and more than a few others here have had excellent results with Mogami Gold Studio, which btw is arguably the de facto cable of choice in pro applications.

For other cables and power cords, many here (including me) have been very pleased with Signal Cable products:

All of the above are very modestly priced, but offer excellent value. Also, keep in mind that balanced interconnections in many cases tend to be less sensitive to cable differences than unbalanced interconnections.


Best of luck.
