Power cable from wall socket to power strip

I asked a question which resulted in several new questions.

Is the sole purpose with high end cables to deliver the power as stable and clean as possible?
Is the sole purpose with a power conditioner to clean and deliver stable power?
If these two questions are anwerd with yes, then the first step has to be to buy a power conditioner.

But there are people that says that power conditioners drains the life out of the music. Why is that? What has gone wrong then?

Yes, I belive and I’ve heard a positive change in the sound when I have replaced the ordinary power cable that came with the device. But I have also heard bad change in the sound when I have replaced several ordinary power cables whith ”better cables”. Why is that?

How can the power cable from the wall outlet to a power conditioner have any importance?
The power has traveled through miles of ”ordinary cable” to my wall outlet, so how can this last bit to the power conditioner, that is supposed to clean the dirty power, have any impact on the sound?

I hope you understand what I’m trying to say and what I wonder. I know my English is not the best.

So then.....nothing anyone has written here really matters. WHY do cables matter is your real question.

Because they sound different, that’s why.

I would suggest you alter your "perceived understanding" on how electricity works.

Thank you for wasting all our time. Your English is fine. Your trolling is almost master-level. Have a nice day.

A simple experiment to understand why any external modification or perturbation or modification around an electrical field may matter and in some cases be audible as a kind of filters:

Put a 200 grams piece of quartz on your amplifier, then try with a piece of shungite of the same size... Go from one to the other and listen the difference ; it will be a slight degradation or an improvement , if it is neither of the two try and put them together,...

if your amplifier is on the warm side of thing , the quartz may help it..

If your amplifier is on the cold side the shungite may help it...

If your amp is more balanced the two together may also did something helpful...

In any case the goal is to hear a "change" for the worst or the better and then you will know how the world is not as described in your manuals ...

A varied mix of some minerals do marvel for my Sansui alpha who sound as a tube amplifier  to my ears : more fluid and no trace of dryness or shrill or anything making it a S.S. design ... the sound is meatier and i modify it at will... It is like using different cables to my ears...Usually i keep my recipe without changing it because there is more no need to balance it further ...

No sarcasms by empty head will be  needed when someone  dare to suggest a simple experiment a 4 years old can do... 😊

«Sound need a medium , the air, but sound is not the medium nor the mere waves in it; sound is a real event from the vibrating sound sources or near two sound sources with qualities, localization and duration; sounds are no more illusion than the rainbow, they reflect our own grasp of the sound source and the sound source effect on us» Anonymus philosopher

I start at the source and only use energy from very clean coal.  Diamonds are best but hard to source.  Then focus on cables from plant to substation. 

That provides an airy soundstage.
