Socketman, JohnK is not implying you are an idiot. Another interpretation of his statement is this: Your senses can't be trusted, as has been shown time and time again. In the absence of information to convince them otherwise, most people -- yes, even non-idiots -- will believe their senses.

The fact is, we do have better information about how humans perceive sound. Research has shown that -- and may I point out that acoustic research is performed with equipment that is far more sensitive than human ears -- any break-in that occurs happens very quickly during the first minute that the speaker has ever played. Any changes beyond that are not detectable by the human ear.

It has also shown that adults with average hearing also experience sound in the same way, so a possible defense of "I probably hear differently than you" usually do not hold up.

No need to be defensive. John's dry, clinical posting style is just trying to pass on the facts as he knows them.
