I think he was talking about the lay of the wires.

When cables are made the twist (usually right-hand) aligns with the pins on the connectors when the cable is run one way as opposed to the other way.

When you are making up XLR audio/mic cables, if you run the cable the right direction, when you are cutting and soldering, the black, white and shield conductors will line up with Pin-2, Pin-3 and Pin-1 respectively and you won't have to untwist them in order to make the joint.

Since you are only supposed to strip the shield back for 1 inch or less and because you are only supposed to untwist the conductors for 1/2 inch or less, the better you do the job, the better the cable will be.

And, if you cut and solder the connectors on according to the lay of the calbe, you will have a better end product.

The wire, itself doesn't give a rat's ass which way the electricity goes. It actually goes both ways, really. The "direction" you speak of is only due to the twist of the conductors inside the jacket of a piece of cable.

I use thhn stranded, do not twist any wire, and not only never have hum "issues," but usually get the appropriate curve within 2 db without touching a single third octave control.

I know that I am blessed and annointed. Thank goodness I don't have the problems others do with hum and response. Louis

No, I am talking about 'standard' (unshielded) 2 core loudspeaker cable!!

The manufacturer specified that it should only be used in one direction (from amp to loudspeaker)!!

Needless to say, I couldn't hear any difference whichever direction was used (and I did REALLY try)!!!!

There is no electrical reason why wire needs to be used in one direction versus the other. Wire doesn't care which way the electricity goes. In fact, with audio, the electrons are traveling in both directions, virtually simultaneously.

The only reason I know that wire might be used in one direction or another is, like I said, to make it easier to put the connectors on the right way or, like others have said, to make sure the shields are connected on the upstream end.

If somebody is telling you that the electrons flow better in one direction than the other, unless they have a solid reason which I've never heard of, they are full of it.

When I was at Syn-Aud-Con , the instructor told us years ago that a company was selling a device that "charged" your speaker lines before you hooked them up, then you would have to recharge them from time to time. It was marketed for audiophiles. I guess if you're paying 10 to 20 grand for your home stereo, what's another few bucks you can show off to your friends [Roll Eyes]

If anyone is interested in sound reinforcement, I highly recommend taking the Syn-Aud-Con course. I took mine over 20 years ago and it was a week long class and cost about $600 plus hotel expenses. It's in Indiana across the river from Louisville. It looks like they have training classes in different places now.

No, it's supposed to be a parabolic dish, hung by a single silk thread directly over the exact center of the turntable but the focus of the dish must align EXACTLY with the very tip of the spindle in the center of the turntable.

Yes Randy, I agree but remember that only works on the Vernal Equinox.

If the thread is made from oxygen free silk it doesn't have to be on the vernal equinox.

I sell oxygen free silk for $100 per inch. If you need some, send me a PM. I think I can get you a 20% discount.

And remember if you're in Australia or New Zealand that the electrons flow in the opposite direction so turn the cable around. [Big Grin]

So THAT'S what I'm doing wrong!

..and here I am thinking that turning the cable to face TOWARDS the amp would fix the problem! Ya learn something everyday.

Now, what am I going to do with all this 60 Hz cable I have left over???

The electrons in European cable produce the best sound!

Seriously though, we should start another dedicated thread listing some of the wacky ideas being advocated by hi-fi enthusiasts.

I've come across some very strange analogue-device tweaking ideas in the past!
