Pleasurably better, not measurably better

Measurements are a tool.  Use them wisely!  The end result:   Pleasure.  Ahhhhhh…..🙏

If measurements of individual components AND of audio pleasure of individual listeners could be standardized, we end up with only one components in each price category and probably one reviewer who undergoes hearing tests before each review (LOL) I am of opinion that recording techniques (proven by the simple fact they sound so different, starting with fact that microphones are really different) and individual psychoacoustics (proven by the fact that all listeners in a given room seldom fully agree) can not be absolutely compared because they are what they are: individual by default. Anybody who think that democracy (regardless how you can agree to implement it) is the best system for audiophiles ruling their own principalities, is a dreamer at best and naive fool at worst. Coincidentally, the most objective reviewers and best discussion forums must respect INDIVIDUAL DIFFERENCES.

Happiness is also dependent on the individuals tastes and needs.

You can't baby, you can only measure lust.  🤣

Serious answer though is that there's a tremendous amount of scientific work on human preference and perception.  As you might imagine, much of it is geared to product development.
