Is my view....

I see what you are saying but in these straightened times many of us are
'stuck' with the speakers we have (For whatever reason). So making the
best of them is the only option.

Fair comment.

Speakers get better the longer you have them, in my book. Actually, I
would go as far as to suggest that most people who make a significant
effort to *upgrade* speakers end up invariably disappointed..??

I don't suppose they keep on getting better, because eventually some of
the materials may start to harden or dry out. But I've definitely heard
new speakers improve significantly over a period of 48 hours or so.
