"I figure subjectivists are like religious people and objectivists are the scientists. There is no proof that a new cable, silver fuse, etc improves the sound, but they believe it does As @djones51 said, until you take vision out of any audio testing, there's going to be bias."
mrskeptic, you are assuming objectivists are scientists. Bad assumption. Both are subjectivists. What is subjective about science? Too much blind faith in current knowledge. In audio, that is that the equations are good enough to measure everything, and if it can be measured by current knowledge, then it cannot exist.
Real world, unrelated example that I've brought up before. Kepler's laws of planetary motion could predict the motion of all the planets--except Mercury. Why? The mass of the Sun is so great in comparison to mercury that you need to make relativistic corrections (ie Einstein's general relativity theory) to get accurate predictions for mercury. Newton's theories work fine for the other planets, and Kepler used Newton's work to predict planetary motion of most planets.
The point? Blind faith in science is a form of religion. If Newton's equations (via Kepler in this case) can be limited to specific parameters, then show me the person smarter than Newton that has all the answers.
If anyone thinks that science is some objective monolith without emotional decision making, then they are showing the same blind faith that people today think is reserved for religion.
You can hear things that the physics of sound does not model. And with current knowledge, cannot model.
