Who says cables don't make a difference?

Lol Robert, as I have said, my major is in physics. I am not anti science, I am anti fake science

Anyone with an agenda, pro cables or anti cables, audiophile marketer or audiophile debunker has nothing to do with science....And technology is a servant of science, a slave of scientific endeavour not science by itself...It is truer with the passing centuries.... The more advanced species quit physical technology long time ago.... :)

Dont ask me how i know that.... 

I tried 3 Interconnects direct from my DAC to amps.  Two amps were integrated, one was not and volume was used with the Audirvana player on my PC.
1  Moon Audio Black Dragon 3 ft.
2  Moon Audio Silver Dragon 1.5ft.
3  Better Cables Silver Serpent 1.5 ft.

A few weeks ago we compared #1 to some Amazon Interconnects and 3 out of 3 of us, two were blind noticed quite a big difference.  This time, 1 and 3 sounded about the same.  Then we tested 1 vs 2 on 3 different amps. In every cars we could hear the difference.  3 - silver was brighter.  It is what I would choose for detailed listing, but it would become fatiguing much sooner.   My buddy liked the 1 set better in all situations.  I thought 2 were better on one system.  For the money - #3 was a great way to go.

My net is they absolutely matter on a clean system vs the very low cost cables.  $20 vs $300 mattered.  $100 vs $300 not so much.  And silver (bought used on eBay) near double the price were different.  But different like how you might tune an EQ.   I have not compared to anything higher priced.  I expect I might discern a difference. 

I was surprised that there is a difference, but there is. 

I'll add, I have a DAP that I bought an inexpensive 3.5 to RCA (Y) I was using.  I also incorrectly used a balanced higher end set from same DAP to same amp.  The balanced sounded so much better.  I thought balanced was why.  Reading more, that was a no-no.  Anyway, that Y was left in another location.  I pulled out another Y and was surprised it sounded as good as the balanced.  Both were pretty inexpensive - I'd guess from memory ~$30 and both sounded very different.  So now I am looking for a good Y cable.
 

Many people have done something g similar David, I know the naysayers, and Robert in particular will try to tell you why your test was invalid and you are really just assuming attributes being associated with particular cables because of what you’ve read about them. trust your ears, and as you saw, different people prefer different sounds, so one is t always better than another, but more like one may be better to you, and in the end, that’s all that matters. We are the ones spending our money for our personal enjoyment. Not sure why some feel the need to try to convince us it’s bogus. You’re not spending their money, nor asking them to either.
