The 'quality' of capaciors is an entire irrelevance with something so primitive.
In fact it's almost a complete irrelevance completely unless you buy Asian junk.

I take it you've been 'Audiophooled' by reading magazines written by wholesale
fraudsters. Audiophile was it ?

Graham, why are you so aggressive with me ?
What is your problem ?

I have read it in Farnell catalog.

I have studied Bode, Nyquist, Smith diagrams, Z, Laplace, Fourier
transformations and their digital implementations, ...

So I think I can read technical answers to my "beginners" questions.

Oh, by the way, I must admit that I have miss the training "how to
become arrogant".

Thanks for the link Michael.
I do not want to become EE !
At least good EEs should respect IEEE Code of Ethics (point 5).
