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.

Hey, ain’t nothin’ wrong with being obsessed with good sound. Let’s take a hypothetical case, shall we? OK, now I’m not expecting anyone to believe there can be 100% improvement to sound quality with only one tweak. Even though I personally have experienced that one more than one occasion. But to avoided putting anyone off too much or possibly causing a brain aneurysm in any die hard Skeptics let’s take it a little slower. Suppose you have five tweaks and your system is not all messed up and can actually hear the effects of all five tweaks. For the purposes of argument let’s say the five tweaks are 2 Blue Fuses, the new Graphene Contact Enhancer (applied to only interconnects and the Blue Fuses), a Green Pen for coloring the outer edge of CDs and finally, a spring based isolation system for speakers. OK, that’s five.

Then as each tweak is applied, we ascribe a percentage improvement to each tweak. So for each Blue Fuse let’s say, for the purpose of argument that there is a 15% SQ improvement. Not too high, not too low, right? That’s 30% for both fuses together. Next up, the graphene contact enhancer applied to the Blue Fuses and interconnects only. That should be another 30% SQ improvement at least, you know, being a little conservative. That’s a total of 60%.

Next up, the Green Pen. Now normally I’d estimate the Green Pen about 5-10% SQ improvement but since we’ve just improved the SQ by 60% th Green Pen should score higher, being more powerful now that you can hear the effect easier. So let’s say the Green Pen improves SQ by 20%, fair enough? Now we’re up to a total of 80% since we first started. 

Isolating the speakers should produce even greater results since the speaker vibration will not be allowed to migrate to the electonics. So isolating the speakers, especially after we’ve used four tweaks already, should score, what, 30%?

Thus, with five tweaks, conservatively speaking, we’ve managed to improve the sound quality 110%. Pretty good for an afternoon’s work, eh?

@willemj - with an attitude like that you will never advance in this hobby. Remember the Little Engine that Could? I think I can, I think I can, I think I can! 🚂 Toot, toot!
