Need to do that double-blind.After 15 pages ... I just realize that a fuse affects the sound so much.
I just tested, taking the fuse out and guess what, the sound was affected well beyond hearing threshold
I try to keep an open mind -- especially about analog electronics as it's rather complex (figuratively and literally when talking about some wave forms).
Is there any mathematically or physics justified publications about directional wires or fuses for AC signals? It seems like a total misunderstanding that in AC, the same current flows both ways. Maybe it's confusion stemming from common single panel mains where there's a hot and neutral and ground and people are taught those make a difference (they do for safety, but not for the AC power).
I cannot imagine how one makes a directional AC fuse or wire. Maybe there's a way to make a fuse that performs really poorly in one direction and normally in another, relative for hot to neutral?

The question is: does any or all of those properties affect actual sound quality and noise/emf/whatever rejection.
A shield connected at only one end is very common. While it doesn't affect sound quality per se, it does solve ground loop problems which can cause noise.
The shield can connect one component's chassis or ground to the other, which may be at different voltage potential. That voltage can be carried on the shield. If the shield is an open circuit and used only for screening, no voltage can flow on it.How can a shield solve ground loop issue? If there's a some sort of source of noise which cable picks up, yes shield can help, but ground loop? To solve it you need another path for signal/ground. Shield does not have it, it's just connected to RCA neutral.

I must have confused what you were getting at. What I was referring to is with connecting two fully balanced components, and the common practice of having the shield connected at only one end. If you are using an RCA, then that's another thing.Now I can't tell if you are agreeing with me or not. I clearly stated that shield is connected to one side of RCA neutral. It can't solve any ground loop issues since it's not part of any circuit. Isn't it so?
It has nothing to do with AC vs DC. Directional cables claim that the shield is connected/grounded to one side of the cable. So in theory a directional cable is 1) physically different that non-directional, 2) are different physically when connected n opposite direction.

I've heard that slow-blow fuses tend to 'round off' the transients, and quick-blow fuses tend to emphasize transients. I read it on the internet, so it must be true.

To my recollection, if the conductor has enough impurities in it, then supposedly rectification can take affect, but as in all snake oil type claims, we are talking affects that are not able to be heard by the ear. There are some affects to the fuse elements that can also apply in a similar manner, but again you aint gonna hear them. Like I said, this is my recollection, I do not have anything specific to go on at this time that is in writing that I can find right now. In any case, the rectification would be random in nature so the net effect would be, even at the atomic level, very hard to even measure when considering an audio signal.
