Indeed opinions play a part

Since no component is perfect, one necessarily has to make choices based on preference. My preferences have themselves evolved over a long period of time. The fact that differences exist is not the question for experienced listeners using high resolution systems. The question is which differences are most important to any one listener. Is image specificity more important than harmonic integrity? Is stellar bass response more important than dynamic accuracy? There is certainly no one answer.

So when one speaks of the clearly audible differences among components (using musical content, not static test tones) where the numbers are not supported by the observational data, then which conclusion do you draw?

1. The consistently perceived differences among a large sample of folks (thousands of high end component customers) are completely attributable to merely psychological factors.

OR

2. The testing methodology does not mimic the musical reproduction process closely enough to be relevant. You pointed out the challenge requiring powerful supercomputers to handle testing using complex musical content (which, by the way is how audio equipment is used by the public). Likewise, you have identified the other challenges of conducting DBT tests offered by jj. Your solution? Dumb down the tests to make them more convenient. The result of the simplification process is to make the tests largely meaningless.

Perhaps there are some valid DBT tests that do not contain the flagrant flaws evidenced in the links posted thus far. We're all waiting to see them!
