Jea48,
That was a good article. What I picked up from it was that over 40 years ago he heard something on caps and couldn't measure it at that time.
The ability to take measurements and analyze data has improved dramatically over the last 40 years.
Any of us can quickly do a frequency response curve of our system at home that is probably much more accurate than could be done then. The hardware costs very little and the tools to do so are now free.
I think the simplest thing that can be done is simple measurements of signal into a system from a source versus what is being output by a speaker (of course you can measure at any point in the system). If you can hear something you didn't hear before it is probably something that was picked up by a mic during recording and should be able to be picked up by a mic again. With modern computers it is pretty easy to compare these signals and find A X B differences and inaccuracies in the signal.
There may be some not so well understood principles in audio reproduction, but if we can hear it I contend that is can be measured, maybe not understood, but at least measured.
