Only notaclue has answered my question:

If cables A and B were scientifically 'proven' to be 'audibly different' in both a qualitative and quantitative fashion, confirmed in blood by the worlds most trusted and honoured men in white coats, would there still be an audible difference if you couldn't hear one? (addition of the word 'audible' to satisfy detractors)

notaclue confirmed that there would be and that his ears would be deficient. In which case, how do you go about getting out of bed in a morning. If you can't trust your senses, how do you have faith in your own existence. Or is the 'world' communicated to you chaps through other mediums, as i have already proposed.

And if the answer to the above is No - then what is the point, as i already keep emphasising - other than for the thrill of it.
