Directional wires/cables

1) Your first statement above is completely incorrect. A fuse (to take your example) does not carry a voltage (whatever that means, since it is a meaningless statement in the first place). The idea of ’source’ and ’load’ are irrelevant in electrical theory; you can represent any part of a (linear-ized) circuit as a ’source’ with an ’impedance’ that is connected to the rest of the circuit ("load"). The fact that we as humans interested in hearing sound being reproduced interpret one component as a source and another as a load has nothing to do with the way in which electrical circuits behave.

         I didn't bother responding to the total nonsense above, knowing that the uneducated poster/poser would completely miss the implications/ramifications, were I to mention/post anything, as regards Poynting Vectors*.

                                     I'm certain: you do!

                                       Happy listening!

I’d like to say another thing. For the last 1,000 years, science has always been about challenging ideas, old and new. Science can give you some answers but rarely its entirety, There are 2 more questions for every answers that’s been made.

That is Science. If you think what you know is absolute, you are betraying Science on a fundamental level.

See, I couldn't even spell PhD correctly. I do not have the higher education of many in and around these forums. I do have big ears though. :) Thanks for all guys, it is appreciated. Sorry if people get angry over it. I for one, do not.

I am not 100% sure if cables can be directional or not, but if the manufacturer suggested a direction to install it in, I'd go with that.
