Furutech Nanoflux speaker cables

@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.

i believe i have seen many YT vids by audio engineers w/ test equip FAR beyond high school physics! dissing the directionality thing so i seldom see any proof someone does blind A -B tests when they insist they can hear a difference ! 
so of course noone believes you why should they? 
you refuse to test reasonably and fairly 
real science means you test variables realistically and empiricly so called "cable deniers " are IME honest people reasonably expecting proof SHOW it ! 
you can certainly get a few steps up fr lamp cord and not spend silly $ 

@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.

Seems they come with spade connectors for the amplifier end and banana connections for the speaker end.

Interesting that the OP can hear a difference but does not know which is 'better'.  I accept there may be a real subjective difference, but to be objective, the comparison should be with unamplified live music.  (Amplifiers, loudspeakers and microphones introduce their own distortions).  The direction that sounds more realistic should be counted as the better.

If there is a difference, should there be twice the difference if the cable length is doubled?

I could tell an immediate difference between Kimber cable 12 tc when I went with  Furetech DSS-4.1 with the their top end spades and bananas.  There is an arrow for direction of said cable and I run them like this, doubt I could ever tell a difference in direction but doesn't hurt to use as directed right?
