Lets take a view to high class stereo equipment.
Think we find a logarithmic curve there :
There is not more difference in quality (mostly sound) if you got one for 5000 Euros and 10,000 Euros.
Thats a little bit excessive, I know, but more or less its true.
(My old stereo was ca 3000 DM in 1972, a real fortune, but all is fine in 2020 : Thorens, Braun, Revox & Akai)
You will never hear any difference if I play a 5000 or 10.000 equipment, as the human ears can not judge.
(But if I TELL you : you MUST hear a difference, you WILL a difference. hehehe!)
Cat’s ears are much better than humans
But they usually go for mice and not for speakers.
