the logic being stated is that if science can't prove it,then it must not be so. then you guys back that up with, if science can't prove it isn't so because we can't measure it, then we can statistically eradicate it with testing using real ears, attached to real humans.
that's all great, but what if the act of testing is sufficient to remove a persons perceptability to the effect they would otherwise hear. then you can't measure it, can't test for it, but remain able to hear it..
You need to provide some evidence to show this is case.
everyone just assumes there are only two states for the case, off or on, cold or hot, like a lightbulb...
well i disagree, there's a third state, an untestable state, equivalent to a just been turned off lightbulb, still warm enough to burn your hand, but not bright enough to read by.
i firmly believe that differences between cables do exist, not anywhere like you would need to be able to justify good money on them though. just subtle tone controls, unless you have seriosuly weird inteactions in your set up.
If cables etc are untestable, how do manufacturers research them to make them in the first place?
Some of the vendors like to tell us through there advertising that they spend a lot of R&D. If these things are untestable / unmeasureable, what are they doing?
The fact of the matter is, that signal transmission along cables, both analogue and digital has been researched and has been well understood for decades.This research has been carried out by serious specialists in major industries, not a minnow industry like audio, but big industry applications like Nuclear, Military, IT. and nothing has been found.
May I also suggest an excellent read for anyone who is really interested in human hearing and all of its pitfalls
