... Without love for music such attempts look to me as absurd ...
Well, this is subjective. When you like the music it doesn't matter from what kind of source it is coming, MP3, Car Stereo or Gramophone.
High End Audio actually used to have a goal: perfect reproduction of the sound of real music performed in a real space. That was found difficult to achieve, and it was abandoned when most music lovers, who almost never heard anything except amplified music anyway, forgot what "the real thing" had sounded like.
Today, "Good" sound is whatever one likes.
