I respect their hearing acuity because I've witnessed them working with their ears. I think that is valid. Nonetheless, you raise a good point - we all hear with our own ears and we have to learn to trust them, and calibrate them as best we can.

In general, what you suggest is probably true. Others' claims only reveal to us that somebody else "claimed" to hear something, and "may" have heard it. Beyond that, we don't really know anything.

This site is like finding my perfect Les Paul. Incredible wealth of knowledge. Thanks for being open to midnight mixers like myself to explain why.
