Well of course you're right. Still this ''and other parameters which may also need to be measured'' is at the crux of the issue for me.

My position is that every aspect of the listening experience can probably be included in the scientific domain of 'the measurable'. The trouble is that so far no-one knows what to measure or the full impact of different measurements on the listening experience.

By all means let's ensure that the cables are equal in terms of inductance and capacitance but if they measure the same in inductance, capacitance, and any other criteria as yet undiscovered, they will of course sound identical. It's the other criteria that we haven't got a handle on yet.

Incidentally, this is not only true for cables but also for amplifiers, cdps, speakers, etc. We don't yet know exactly what to measure and we don't know what weights to give the measurements.

For instance, we can measure the 2nd harmonic distortion of a speaker at say, 1kHz and 20W to be 5% and the 3rd harmonic distortion may be measured to be the same. Nothing in the measurements tells us that most people would find odd harmonics more obnoxious than evens.

The truth is that there is no measuring apparatus currently existing that can even approach the sophistication, sensitivity and scope of human hearing. Millions of years of evolution achieves more than half a century of engineering.
