Why don't you prove to everyone else that they are not versus demanding that everyone else provide you proof.Because I am not the one who wants audiophiles to be persuaded that progress is being made in speaker design and that speakers are getting better. Its the speaker industry and audiophile community that is responsible for that narrative. And as audiophiles it is our duty to challenge not only what the speaker industry wants us to believe but also to challenge our own beliefs and actions.
Speaker designs do not get better with time, by default unless progress is made. So there is no proof required of that. It is self evident UNLESS proven otherwise.
