“Duke” ?
Saying reproducing the frequencies of music - any less accurately than “Spot On” -is simply to accept the failure of today’s technology. That’s been a common problem with mankind in general and is why we laid breakthroughs that eventually move us forward to a new paradigm.
Its interesting to me that responses to this thread have virtually all been to say why frequency response is unimportant.
“Groupthinking acceptance of the status quo”?
i suggest that in a very few years; when dead flat frequency response is common; the invaluable contribution it makes to reproducing sound will be considered a “no brainer”.
Just my 2 cents worth.
