It has nothing to do with opinion or technical specs, it has to do with attitude. And you've got the causation backwards, JC usually says something insulting ("impolite") [to those with more actual knowledge and/or experience with the topic] and then the usuals respond (not instigate).
The real problem is that JC doesn't honestly know when he's being insulting so what he thinks is an attack is really a defense.
In JC's defence, being condescending is par-for-the-course with someone of his high credentials, long career, age and using a new mode of communication (text only) with a highly-mixed audience.

As far as the Silmic caps are concerned, I do not normally put them in my designs, but I now use 2 designs with Silmic caps in them. First, the OPPO 105, and second, the Sony FM tuner that I modified by removing the ceramic coupling caps and replacing them with Silmic caps in a critical location. The Sony got the old Silmic, and the OPPO got the new Silmic caps, both sound OK.
It is ironic that the German educational system allows for this sort of audio research. If we tried it here, it would be rejected as 'subjective nonsense'. The poor PhD candidate would be told to take on a more 'scientific' topic.
Now, 40 years ago, when I first met with engineers from Switzerland and Germany, I found the opposite to be true.
It was very difficult to get new ideas across, especially since we were 'crazy' Americans. Now, the Munich Audio show is opening as perhaps the greatest audio show on the planet, and a whole floor dedicated to 'tweaks and mods' etc. The new German is apparently more open minded than in the past and just loves to indulge in hi end hi fi, much like we Americans did in the 50's and 60's, the Japanese in the 70's and 80's, and now Germany appears to be taking over since 2000. Good for them, as it is now almost impossible for hi end to exist here without overwhelming criticism by those 'who know better'.

How do you know what "sort of audio research" that this is without having actually read the dissertation?
What record have I set, SY? I AM happily surprised that my comment even got to surface.
It is unfortunate that you and I disagree so much, but I have to stick to my experience, and that says that it is not easy to make 'successful' audio equipment and there is more to it than just standard test measurements. That is why I bought new test equipment rather than a European vacation or some such. Perhaps, I can find ways, much like Ed Simon does, to make the 'subjective' into something relating to 'measured'.
At this time, I am just learning the machine, so the standard tests, like harmonic or IM distortion in a capacitor is good practice, but I could do that 40 years ago, perhaps more sophisticated tests will bring out even more problems with passive parts, as well as whole electronic assemblies, that will help me avoid the 'bad' and tend to use the 'good'.

When it's 6, 8. or 10 decimal points, it makes it negligible.
I simply point out issues I've dealt with as well.
The air has a significantly lower dielectric constant than the plastics. Trapped air will modify the voltage field geometry, and where the air is will be more prone to breakdown. Think of it like an insulated wire. When an insulated wire has a voltage on the conductor, the outer surface of the wire will also have that voltage. This is due to the ratio of the capacitance of the dielectric to the outside world. That is why hv lines in the old TV's attracted dust. Richard's explain is additional info..
Ed, you must find a primer on this stuff. You've no clear understanding of E/M.

A study that I was just reading in a very different forum, aerospace. Thought it may be interesting to someone here so just posting it for any reference someone may.
