I request anyone wanting to add personal flavor of "colorations" in a sound system's "voicing" through equipment purchase to play around with a simple EQ. At least the simple 5 band EQ on amazon music or other apps and hear it through a pair of even cheap headphones. Take the EQ in each band to the extremes and hear how it sounds. That will be some real information/education regarding which part of a supposedly completely "objective" parameter such as frequency response affects which part of what we hear.
In my opinion, there is a reason behind why objectivists run behind measurements, at least the frequency response. The objective is not "flat" or "accurate". Most often it is to strike a balance for those who don't want to change EQ settings for every song that is played. There is no grand truth in audio. It is all perspective colored by our inherent biases.
