Sound is way to subjective and has way too many variables.
It's like measuring paintings to see if you like Picasso better than
Van Gogh.
I've talked to quite a few of the most successful audio designers
and they all agree that the tests don't tell the whole story. You
guys are trying to make science out of art and high end audio is
somewhat of a mixture of the two.
Yeah....I don't buy into that at all. Technological advancements are based in science, not art.
It's not magic. Calling it art is conjuring and attemptimg to shroud the science in mystery.
Synergy in audio, to me, is just ameliorating deficiencies to suit someone's tastes, which is fine, but let's call it was it is.
Musical instruments are made better sounding today than they were in the past due to science and understanding of materials and physics. Before, development and advancement was through trial and error. It was stumbled upon, and became known as art. It's not talent, it's knowledge.
Ask any modder who modifies gear, and his mods are rooted in his firm grasp of science, and sonically, is shows.
I own numerous guitars and vintage amps. They are all modded to some degree, and perform better than stock. All the mods are done by people who know science very well, and the mods are rooted in science.
I mod my own guitars. I can tell you what I do, why I do it, and know what the results are going to do. Any variables in sound can be attributed to the fact that they're made of wood, and that no two trees are the same.
And before you say that which instrument sounds better is a subjective thing...
Audio is no different. There have been, over the last number of years, a number of vast improvements in driver technology. Motor structures, materials etc... Science and technology is making better transformers, capacitors, inductors, wire etc....
I see science as the leader in advancing audio, not art....
Keep in mind, it's science that invented all the different brushes, paints and canvas that artists use.
Science is also what created all the instruments musicians play, not art.
