... abit confused: how does a power cord affect the presentation of sound...
What is most disheartening is the usual level of debate in these threads. Most often it goes something like this: Yes they do. No they don't. Yes they do. No they don't. Yes they do... Many cable manufacturers don't help, with the promotional verbiage that makes any electrical or electronic engineer roll their eyes. I quoted Wireworld's claims above. Can anybody comment on them with some reasonable degree of level-headed knowledge/insight? |

I don't claim to know what "triboelectric noise" means, but a quick Google search: https://experience.molex.com/triboelectric-noise-in-medical-cables-and-wires/ As for blocking outside interference, I am pretty sure they are talking about blocking stuff like radio, tv, phone signals etc. something that @boomerbillone described in very good details right above |
Let think about it. If you're saying the cable is the last 3ft, then why would a power supply be any different? That is the power supply is the last one after many miles of cables, just like the power supply cord as the last 3ft, then why a power supply would make a difference at all? People who are using water analogy and conclude that a power supply cable should not make any difference. But electrons are not water. Before you turn on the kitchen faucet, there is no water in the kitchen in the first place. On the other hand, before you power up your equipment, the electrons ALREADY in the equipment. Look at the tiny fuse in your equipment. You intuitively think that it has to be the bottleneck but obviously that is not the case. Now if you're using a power supply cable as tiny as the fuse, things won't be very good. Your equipment may not work properly. Why is it that a fuse can be tiny and slim, but not the power cable? Because electrons are not as intuitive as you think. |
