Just to be clear in my head, we are talking about AC audio signals without a DC bias and not audio signals on a DC Bias, correct?

Haven’t you been paying attention? Cardas is what we call fat and happy. 😆 |
To restate my point about Yter cables and directionality - apparently, according to what Yter says on their website, they have some special metallurgical technique for eliminating or minimizing the effects of directionality by making the metal conductor more homogeneous than it would otherwise be, you know, by virtue of the wire manufacturing process, which biases the crystal structure in one direction over the other. Maybe they pour molten metal into molds, who knows? In any case, that presumably explains why Yter doesn’t use arrows 🔜 on their cables. Carbon conductors and liquid conductors I.e., Teo Cables might also circumvent directionality by being homogeneous.

@alexatops, I know you know this but... To answer your question and stay away from the debate on directionality, try the speaker cables in both directions (could mean multiple variations) and listen for a preferred direction. Whatever you decide upon always use the speaker cables in that manner. I don't believe Cardas marks their cables with a direction of use for whatever reason? |

amg56 The only reason cables are directional is that they may have different plugs on the ends. >>>>>Actually, shielded cable with shield connected at one end only is an example of a cable that is directional. For a shielded cable to sound correct it must be connected in one particular way. If it’s connected the wrong way it will still work but it (usually) won’t sound correct. But I’m not referring to shielded cables when I discuss directionality, I’m referring to unshielded cables. If all cable manufacturers controlled their shielded cables for wire direction AND shield direction, that would produce the best sound. Follow? |
Wire IS directional. Current can go one way. Or current can go the other way if you turn the cable is reversed. Anyone seen a house or major transmission line electrician check for directionality in AC cables? I also have not seen DC transmission cable checked for directionality in solar panels to inverters, is a good example, or caravans which use DC power for fridges, televisions, stereos or microwaves. The only reason cables are directional is that they may have different plugs on the ends. More HiFi voodoo stuff. |
>>>>>Exhibit A of not knowing what the word directionality means. To think some people accuse me of shooting fish in a barrel....🐟 🐟 🐟 “Not to start a flame war...” Funny! 😀geoffkait, I'm pretty sure that I know what "directionality" means, besides that it has no meaning when it comes to audio cables. FYI I spent 20 years designing metallurgical processes, quality assurance examinations and stress test programs for metal parts. Including cables. But what do I know? Have you taken a college-level (or high school) physics class? |

Not to start a flame war, but there is simply no such thing as a unidirectional audio cable using copper or silver as it's conductor. It IS possible to introduce bias and selective resistance onto a conductor through active (powered) means, and, of course you, can manufacture semi-conducting materials to do all sorts of interesting things with current flow. |
Geoff says "i just saw where Yter mentions their cables address homogeneity of the conductor crystal structure so maybe they have a handle on directionality. Final multiple choice exam for Geoff, not pop quiz, rpt, not pop quiz. If the manufacturer has a handle on wire directionality, and does not indicate what direction said wire should be installed, either: 1. His employees forgot to mark the directionality on the wire? 2. His employees lost tract of the directionality so didn't mark the wire either way?, or 3. The manufacturer doesn't think you can hear a difference regardless of the direction the wire is installed in the audio application? |
As if I needed to repeat myself for the millionth time but all cables are directional 🔜 whether the manufacturer acknowledges it or not, or if the cables are marked or not. anything with wire in it. (Sometimes manufacturers are a little bit slow on the uptake as it were or they never got the memo.) i just saw where Yter mentions their cables address homogeneity of the conductor crystal structure so maybe they have a handle on directionality. |
