Furutech Nanoflux speaker cables

Top-of-the-Line Furutech Nanoflux NCF Speaker Cable
Comes with CF-201 NCF(R) Spades for the Amplifier and CF-202 NCF(R)
Bananas for the Speaker Other Combinations on Request

this is off their website, unless you have the one in 1 million where a guy orders it the opposite. Most likely when they talk about other combinations it’s spade to spade or banana to banana. Also there are different sizes of spade connectors,

i’m pretty sure that if you hook them up the way the manufacturer says and leave them there for a couple days and then do a switcheroo. You will definitely be able to tell which way is correct hopefully.

sorry about having to deal with the CDs(Cable deniers). I remember once when I got a pair of MIT Speaker cables that made it so that you could hear the ridges of the thumb as it strummed across guitar Yet after a week, it began to hurt my ear so bad that I ripped them out of the system. Luckily for me I found The Cable Company and they gave me a really good trade-in and now I’m rocking synergetic research foundation speaker, and four power cables(Plus some Audioquest, monsoon, black beauty, carbon special cables) No way does lamp cord sounds this good.

@gkelly The guy I borrowed these from showed me the invoice where he specified bananas at the amp end and spades at the speaker end.  He must be the one in a million.  And The Cable Company lets you specify terminations for each end of the cable according to amp and speaker sides.  I agree it is a little unusual to specify spades for the speakers but you need to realize that every Wilson speaker made only takes spades so definitely not one in a million there.

The simple fact is where the terminations are doesn't say anything about what directionality the cables might have.

@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?
