I am wondering why high-end amplifiers are still so expensive. Amplification should be a solved problem by now.
Also, what I miss most in the whole sound chain is that I can't change the volume of the tracks that existed before they were mixed into a single track. For example, making the volume of that trumpet in the background a little louder, etc.

I think it's a bit like why Gucci handbags are still so expensive. Because they are high end; there are people who are willing to spend that much, even if what I would call an engineer's assessment "do I get a reasonable bang for buck ratio" clearly answers NO. People by an experience, they buy a feeling. And it may be money well spent for them.
