What do the arrows mean on my cable?

@esarhaddon : show me a physics textbook where wire directionality is mentioned and discussed. If such a property exists surely it would have been measured and quantified over the past two hundred years!

What's the fuss? If the cable has arrows, is it very hard to hook it up following those arrows? hardship much? Or put it opposite of the arrows if that's what your heart desires.

I assumed that it was common knowledge that the arrow always points away from the source, and ultimately toward the amplifier. I have no idea if it makes a difference, but I just do it that way anyway in case it does.

Jason I would suggest you talk to the engineers at the manufacturers of these cables. They seem to feel they have something to talk about. If you wish to come after me I suggest you come after something that I ORIGINATED. I have spoken quite a bit about my own theories and designs. That is unless you are only exercising your typing fingers on your celliophone. Actually, show me in some Physics textbooks about Single Crystal Copper or OFC concerning conductivity. THe thing is, it's been a day or two since I have read any up-to-date physics books relative to the subject and I would doubt if there weren't some taking about this, at least in a theoretical manner.

Actual measurements?

Digital interconnect...

A Transport of Delight: CD Transport Jitter

Robert Harley  |  Nov 1, 1993

 

After measuring the first two products (the PS Lambda and the Panasonic SV-3700), I went back and repeated my measurements to make sure the analyzer was giving consistent results, and that my test setup was correct. When I remeasured the SV-3700, I got about half the jitter than when I first measured it!

What caused this reduction in measured jitter?

Changing the direction of the digital interconnect between the transport and the jitter analyzer.

This phenomenon was easily repeatable: put the cable in one direction and read the RMS jitter voltage, then reverse the cable direction and watch the RMS jitter voltage drop. Although I'd heard differences in digital-cable directionality, I was surprised the difference in jitter was so easily measurable—and that the jitter difference was nearly double.

To confirm this phenomenon, I repeated the test five times each on three different digital interconnects. One was a generic audio cable, the other two were Mod Squad Wonder Link and Aural Symphonics Digital Standard, both highly regarded cables specifically designed for digital transmission. The generic cable wasn't directional: it produced the same high jitter in either direction. But both the Wonder Link and the Aural Symphonics had lower jitter levels overall, but different jitter levels depending on their direction. Moreover, the generic cable had higher jitter than either of the two premium cables—even in the latters' "high-jitter" direction.
