Furutech Nanoflux speaker cables

@gkelly As far as I can tell there is no writing on the cables that could be interpreted that way.

@roxy54 Thanks.  I suspect you are right but I would like certainty rather than probability LOL.

@roadcykler You got to love the cable deniers who think they are in possession of an ultimate truth and who can't be bothered to even listen for the differences that their high school physics courses can't explain. Enjoy your lamp cord and if you ever get around to actually using your ears feel free to apologize for your particular brand of nonsense.  In the meantime, please stop trolling and polluting other peoples threads.

@quickjack1234 The moment you step up from lamp cord, assuming the impedance, resistance and capacitance of whatever other cable you are using is the same, that is the moment you have left the realm of whatever it is you think can be measured by "audio engineers".  So if you are a cable denying objectivist that is fine.  But if you are spending your money on anything other than a mechanical transducer then are are also a hypocrite LOL.  

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.

@richardbrand If you actually look at any website that lets you purchase these cables, instead of generalizing from other cables, you would see that you can specify whatever connector you want for either end.  They don't "come" configured a specific way.  

@stephenjfoster Believe what you will, but unless you are willing to listen your opinion has no real validity in my opinion.  It isn't like I don't understand the basic physics and electrical engineering that supposedly governs what a cable can and can't do.

@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.

@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?

@brunomarcs Thank you.  Finally a post that actually contains useful information.  I had missed that nugget of info buried in Furutech's marketing BS.  For anybody else interested in this the actual text is:

"Furutech specifies α (Alpha) Nano-Au-Ag OCC Pure Transmission conductors - one of the best conductors Furutech engineers have found for sound reproduction - terminated with beautifully engineered high-performance rhodium-plated nonmagnetic pure copper spade connectors for the amplifier end and rhodium-plated banana connectors at the other end. "

And you are wrong, I wasn't trying to drum up anything.  Perhaps it was naive of me to hope that I would get a response from somebody who actually owned the cables rather than a bunch of people with opinions based on, well nothing.  But this is Audiogon and pointless debates between uninformed people seems to be the main reason for this site.

It does still leave open the question of whether the company that sold my friend his cables simply ignored his request to terminate the cables in the opposite of the standard way.  He has contacted them and I will post whatever response he gets.  

@stephenjfoster For some reason you seem to think there is an element of religion or faith involved in any of this while forgetting that science is based on observation and experience.  Now I agree with you that subjective experience should be viewed with skepticism.  And a simple model of electricity would assume that LCR (inductance, capacitance, and resistance) is adequate to explain how cables work. That would suggest that all cables with identical LCR are the same. In fact, there are all sorts of credible explanations about how changes in the geometry, materials, shielding, and quality of construction can impact the signal.  Figuring out which, if any of them, are true isn't something I care about.

I started the journey buying spools of 12AWG OFC copper from Amazon.  It is only my experience based on years of critical listening and hundreds of level matched A-B comparisons that ever caused my hard earned dollars to be spent on anything as frivolous as cables.  

For me, the bottom line is even though I am not religious, if God appeared before me you can be d*mn sure I would change my mind and become a believer (after checking for mental illness).  You could discount it as my subjective experience, in the same way you discount that cables can make a difference, but for me it would simply become a new fact about the world.

You might want to spend a moment on self-reflection.  You aren't an audiophile and you haven't posted any information that any well educated person who has spent a week in this hobby doesn't already know.  For some reason you made strident and insulting posts that assume everybody else is stupider and less informed than you are.  Maybe your ex-wife is right?
