The fix is simple, I just boost the treble control a tad until I can hear those frequencies once again. It's not rocket science, it doesn't have to be 'correct' to the dB, just enough to make the music sound nice again.
I neither said that it can't or that it shouldn't be altered. But it is true that folks who want their hi-fi to do what it says on the tin (reproduce with high fidelity) wouldn't approve of altering the signal in any respect (other than amplitude, and the Fletcher-Munson curves mean that serious listeners take a position on that too). These days with digital signal processing it is possible to do a lot better than just boosting the treble control a tad. A good friend of mine has hearing aids which have been programmed, as far as possible, to restore his detailed hearing sensitivity to that of a much younger person. He's delighted with them - mostly, he says, because he can now distinguish birdsongs again when he's out on a country walk . They mean he doesn't need tone controls on his hi-fi either, although personally I approve of them if there's nothing better for getting the hi-fi-plus-room behaviour closer to optimum.

There is something better of course. I've just acquired one of these https://www.minidsp.com/products/min...minidsp-2x4-hd along with its matching calibrated mic. All I need to get now is that rarest of things - a round tuit !

Cheers,
