power cord directionality
arrwax So let me understand. are you saying vibration can have a negative effect on how electrons flow? If you shake/vibrate any wire enough, it is possible to change the position of an electron? >>>>I’m certainly not saying that. Electrons don’t flow, for starters. Are you new in town? 😀 |
isochronism Now I wonder why was it even bothered to be labeled since it only connects one way..... (?) >>>>Good catch! |
I was kind of hoping you could tell me. Just a gut feeling? Oh, well, that’s the way it goes sometimes. 🙄 By the way Poynting angles are not (rpt not) incompatible with the idea of vibration distorting the signal in cables and wires. Besides, if the signal didn’t travel in the conductor it would matter what metal or purity was employed for the conductor. |
A picture is worth a thousand words. The signal travels in two directions 🔛 as it alternates at whatever frequency applies, as someone said. But you only care about the signal when it travels in the direction of the speakers. You can forget about the signal whenever it’s traveling in the opposite direction 🔙 because it doesn’t affect sound quality. The only signal that affects SQ is the one that is traveling toward the speakers. 🔜 |
That is the exact question I’ve been asking on many different threads here for a very long time for the last few years. No one seems to know, or if they do they’re not sharing. It’s similar to the question, why does the effect of vibration on cables and wire like tonearm wire change the sound? It has to do of course with what is the “audio signal” through wire and how does the signal become distorted? I have even offered prizes to the winner. Share, share! |
optimize Yes, you can’t turn a power cord backwards. And you should never be able to do that (Imagen two male ends and one is in the wall and the other end is becoming deadly..) When you build a power cord then if it has a screen. You may connect the screen only in the wall side so all interface that the screen is getting is drained to earth at the wall side (you do not want to connect the screen to the ground in both of the ends like a conductor). But it is irellavat if you are not building your own cables when you can’t turn it around anyway as a user. But it is another story with RCA interconnects. There you CAN turn them around (because they are not deadly). And the screen is only attached at one of the ends of the cable. Usually the screen is attached at the source component end (that is one of the reasons it has the direction label). But what happens if your source do not use the ground in the power cord (no power cord on passive preamps for example going to power amplifier)? Should we flip the interconnects so that the screen drain is at the receiving end and that component use ground? >>>>>Dear Mr. Optimize, you’re missing the point of why it’s important to construct the cables and power cords from the start with directionality of wire in mind. The shield is a separate issue and should be considered along with directionality of wire during construction. For cables without shield the manufacturer only need honor the directionality of the wire during construction. It’s not rocket science. 🚀 |
roberjerman If wire has "directionality" why hasn’t somebody in the past two hundred years found a way to measure and quantify it? Instead all that can be said is "my golden ears tell me it is so". This is NOT a scientific method in the least! >>>>>Observation - also known as empirical data - is a cornerstone of the scientific method. |
