Furutech Nanoflux speaker cables

@pinwa "Someday I hope you and @roadcykler and all the other deniers actually get to hear high end systems that permit you to do A/B listening tests of different components that simply can’t possibly make a difference but do. Hearing is believing."

I’ve come across MANY many people in the audio hobby that can’t tell the difference between amps and between dacs. To believe these people can tell the difference if they just give cables a try is just not gonna happen.

" I agree it is a little unusual to specify spades for the speakers"

If you have kids, they can easily break off the banana plugs when inside the speaker if they just step on it. I’ve had it happened before. Spade would be almost impossible to break in this situation.

One final note I'd like to add about cable. The cable deniers also never care for the quality of the terminal connectors of cable. Which IMO is silly thinking. 

@pinwa

I looked at Furutech’s website as quoted by @gkelly, and assumed that, like Oscar Wilde, you would be easily satisfied by the best! Sounds as if you knew the answer anyway because you borrowed custom cables terminated in reverse.

Furutech also says its NCF "generates negative ions that eliminate static. Second, it converts thermal energy into far infrared. Furutech combines this remarkable material with nano-sized ceramic particles and carbon powder for their additional ’piezoelectric effect’ damping properties".

As a physicist I am sure you will agree that negative ions increase static, which is a surplus of electrons. As for converting thermal energy into infra-red, that’s what everything does around room temperature. But wait, there’s more: mechanical vibrations are converted using the piezo effect into yet more electrons, presumably to give some added snap, crackle and pop!

But now I am really confused - the borrowed cables have spades on one end and bananas on the other and you hear a difference when they are swapped, but your speakers only accept spades. What gives?

@richardbrand I am not a physicist nor do I own speakers that only accept spades.  I'm certainly not going to argue that Furutech's marketing makes any sense.  In fact, I would agree that it sounds more like nonsense.  And if you read what I have written,you will find that I haven't expressed any opinion about the cables other than noting that they sound different depending on which end is connected to the amp and which end is connected to the speakers.  

I believe there have now been 12 people that have responded to this thread and not a single one actually knows anything about these cables and I suspect most of them haven't ever bothered to compare cables in a highly resolving system.  But all of those people seem certain that they actually know some sort of absolute truth, but without being in possession of any actual experience or observations that would lend any credibility to their assertions.  Curious isn't it?

I went back and re read your post. The manufacturer says they build these cables with spades on amp end and bananas on the speaker end, that would be the directionality of said cables. Other combination of ends if requested, so if you were to buy these they would most definitely have an arrow on them or other tell tale sign on which direction they go.
 

 They would say which way they go and your asking members here how they would know which direction?

You were trying to drum up some criticism and start a cable bashing from a member, you've stated your purpose's in your  last post,  that's my take on it. 
 

if you were genuinely interested,  you'd asked if someone else had these cables to begin with and how do they know which direction?

Extrapolating from Furutech balanced ICs like Reference III, which cannot be reversed for obvious reasons, the filter would go at the source end, as @roxy54 said.
