Directionality of wire

I am a fan of Chris Sommovigo's Black Cat and Airwave interconnects. I hope he does not mind me quoting him or naming him on this subject, but Chris does not mark directionality of his IC's. I recently wrote him on the subject and he responded that absent shunting off to ground/dialectric designs, the idea of wire directionality is a complete myth. Same with resistors and fuses. My hunch is that 95% of IC "manufacturers", particularly the one man operations of under $500 IC's mark directionality because they think it lends the appearance of technical sophistication and legitimacy. But even among the "big boys", the myth gets thrown around like so much accepted common knowledge. Thoughts? Someone care to educate me on how a simple IC or PC or speaker cable or fuse without a special shunting scheme can possibly have directionality? It was this comment by Stephen Mejias (then of Audioquest and in the context of Herb Reichert's review of the AQ Niagra 1000) that prompts my question;

Thank you for the excellent question. AudioQuest provided an NRG-10 AC cable for the evaluation. Like all AudioQuest cables, our AC cables use solid conductors that are carefully controlled for low-noise directionality. We see this as a benefit for all applications -- one that becomes especially important when discussing our Niagara units. Because our AC cables use conductors that have been properly controlled for low-noise directionality, they complement the Niagara System’s patented Ground-Noise Dissipation Technology. Other AC cables would work, but may or may not allow the Niagara to reach its full potential. If you'd like more information on our use of directionality to minimize the harmful effects of high-frequency noise, please visit or the Niagara 1000's owner's manual (available on our website).

Thanks again.

Careful my friend, or you’ll be relegated to the loony bin. It appears that your own experiences are not good enough, no matter how many times you’ve heard it. You have to submit to rigorous double blind testing, before a panel of others peers, who are predetermined to just write it off as of no significance. 😉

All the best,
Everybody know wire has a direction.  The amp is at one end and the speakers are at the other end.  The music flows from the amp to the speaker.

It is important to reverse your speaker wires every 2 or 3 songs just like you rotate the tires on your car.

You do this to relieve electron fatigue caused by heat buildup in the wires.  Playing some cool jazz has a similar effect.

Also, playing rap music on wire - just once - will hurt the wire and it will need to be frozen and slowly thawed before the effects of the rap music will be gone from the wire.

I would have to keep my car radio off if what you said is true. Rotate my tires after every two or three songs?   ;)

 I'd be better off listening only to talk radio if that were the case....

I still think those who can not hear the differences may simply have an unclassified condition, like colorblindness is to the eyes.  In this case,  its with the ears.


I have tested directional wires, all this means is the wire was drawn and Angeles
In that direction , and through my Electrostats speakers most any changes can be heard . Slightly better a bit more pronounced . BUT, if you leave opposite for 24 hours  everything is pretty much =.  It is Not a permanent change,
Cryogenic immersion is a permanent change for example and  + result
For example.
