Why is science just a starting point and not an end point?

Are you a politician? You manage to avoid answering the question.

100 trained people...

Education matters!!!

How do you think Andrew Jones or John Devore tune their speakers at the final stages? With a calculator??? Or Nelson Pass with his amps???

I didn't avoid anything. Your 100 trained people would fare no better than the trained people in 10 years of ABX testing. Are you a politician that avoids the obvious? 

Speakers aren't amplifiers we were discussing amplifiers. I agree trained listeners would have a better chance identifying speakers.

Pass purposely creates a sound with his amps,  take an amp that measures the same, I doubt in blind testing it would be identifiable.

Science is the starting point of spiritual evolution, and a railing against extremism, science is not an endpoint of the road... Only scientism claim to be this endpoint....But science is not scientism... The departure point and the railing is NOT the road...
