The "best" signal is such a temporal thing. It is guesswork even by the original engineers.
They are trying to guess what equipment you will hear it on and what will sell the most.
The idea of being a purist, and instead of using tone controls swapping speakers and cables to achieve the best reproduction is absurd.
My problem with tone controls is only their implementation. I've had 2 high quality preamps, one of which had tone controls that were clearly audible, and my current one they are not. I mean by this the sound turned veiled and lost dynamics. I wish all tone controls were great, they aren't, but worth pursuing.
