What about line-neutral swap on power supply cable? 😛
Some audiophiles claime that makes abnormal difference 😱
But explanation doesn't exist

The explanation is that a mains transformer may have asymmetric stray capacitance. Of course, with a high quality transformer this will be less of a problem and with well-designed circuits it won't matter so much. Perhaps another example of "If you can hear the change then your system is not good enough"?
But you don't know how primary and secondary are wrapped.
Take a toroid. Any parasitic phenomena is opposite if you place the toroid upside down, same if you wrap the primary in the opposite way.
Plus each secondary.
How many combinations? Too much, too unknown to make a single "rule".
The audiophile rule is: "line&neutral must be in-phase for each audio electronic device".
No matter how transformers are wrapped and placed.

Now that is daft. I thought you were just talking about the way some people find that a simple swap on one item can bring lower noise. I suspect even that is sometimes placebo, but sometimes genuine.pergo said:
One could even say the noise blanket has smothered or at least veiled the music. Then the electric noise and not compression or some other intended artifact causes the effect you have so aptly stated.
Agreed ! If main cords make a"big" difference one need to look to the power supply as not up to the task.
If line and neutral in is phase, there will be no voltage.....🙄 "Audiophile" rules often doesn't make sense....
I think he meant "line and neutral are the same way round for each item". This is guaranteed for people in the UK with correctly-wired houses and plugs.AuroraB said:
Except a number of figure of 8 plugs are reversable for double insulated equipment.
The only thing I have with a 'figure-of-8' mains inlet is a portable radio I bought about 45 years ago. Everything else has one of:
1. captive mains lead
2. IEC inlet
3. 3-pin wall-wart

Safety first, but this never dawned on me. "This" being the discussion here. The mains inlet & wire nut topics make more sense now.
Interfering not with the speaker, but with the electronics earlier in the chain - the effects are as you described them.
The easiest way to appreciate this, is to "clean up" the system and environment as much as one can, thereby restoring the full clarity - and then introduce various mechanisms that inject interference into the environment, individually, and note the audible impact. That way the listener learns to recognise, firstly, that the sound is being degraded, and secondly what the manifestations are - then you can easily spot when it's happening in an unknown system.
The solution? Easiest and fastest is to clean up the environment, but not very practical - the real world still has to move along, messy though it may be; the real answer is to make the entire playback chain extremely robust, impervious to any external behaviour, by anything untoward. This can be mighty tricky, and frustrating to achieve - but is most certainly worth the effort ...

Got any real proof of how noise affect electronics especially sound, or just anecdotes? Probably not... There has been a lot of research done regarding this, some available to the public most covered by NDAs and other restrictions..... Generalisation is not that scientific.
As to that link for the SD card!!!!! More marketing rubbish. Though the final sentence does say a lot, maybe Michael Lavorgna should ask himself why so much **** is thrown at audiophiles (or more specifically their beliefs), could it be because they talk and believe so much s***e. It must be the only area where people with zero electronic training can mod complex electronics and discover the next hidden thing in sound improvement or discover some major flaw in standard physics that the rest of the world have just missed.....,
I think I could safely say, if enough electrical noise was introduced into the environment of an audio system then the sound could be affected - I might go silly, and say, let's plug in a working, heavy duty arc welder into the socket next to that of the system to "prove" that noise affects electronics ...
So, the real question is, what are the levels of noise required, for a particular system, to have an audible effect? This, I think I can also safely say, depends upon everything, especially the learnt sensitivity of the listener - there are no clear answers, because no-one does any objective measuring of such ...
Does not need to be a welder....a SMPS phone/laptop charger is enough to cast a dirt film/veil over the sound image of typical playback gear.
Fisher & Paykel washing machines also.

Ahhh ... but a welder has a nice touch of drama about it, don't you think ... 😀 ??
Agreed, anything with a nasty electrical signature will do the trick - just trying to get the point across, 😉.
