I contacted Jung after I wrote my paper about ceramic capacitors. My
paper made the point that the COG/NP0 types of ceramics are far superior
to the type that Jung/Marsh tested in their paper. Jung revised his
position, being complimentary to the COG/NP0 types in an AES paper that
he wrote later about RIAA phono preamps.

If you haven't noticed, Marsh is as I type trying to sell golden hi fi
preamps.

Congratulations. I tried to convey the same idea to him and got blown off.

** That corrects almost nothing that was wrong and neatly hides doing even
that.

** No Mark - your advice was BAD.

When you think you hear something unexpected going on then the NEXT step is
to do a scientifically valid listening test - best not to use yourself as
the subject for this either.

The method you espoused ( ie reaching for exotic test methods) is exactly
what has led to all the snake oil products and myths we have now.

Agreed.

Disagred. The exotic testing methods and the search for them are in essence
the cover stories for the snake oil.

IOW, my hobby-horse snake oil is so sophisticated that it makes a
mind-blowing difference in sound quality in almost any audio system, but
generally-accepted listening test technology can't detect even a trace of
it.

** What ?? Try to persuade him to make a reputation and career destroying
move ?

Overwhelming contrary evidence has been published by numerous others -
plus commercial practice has treated the paper as of zero value.

Only the scam artists and hobbyists put any faith it now.

Just a few citations would be nice!

Have you seen the series by Cyril Bateman on this in 2003? Did he
make the same error? It was a much more extensive set of measurements
than J&M. Unfortunately I don't have it in front of me and I don't
recall the details.

Thanks,
Tom

** Which unsupported assertions in the Jung-Mash article did you want

** Yep.

** What error ?

You need to learn what the word specific means.

** Measurements are not he issue - correct interpretation of the results
IS.

You need to develop a memory. The only *specific* error you mentioned
in your own posts in this thread---the coupling capacitor.

** You need to learn to read as well as write - dickhead.

** The whole Jung / Marsh article was about damn *coupling capacitors* -
plus did not use the word "error" in any post in this thread. Not only do
you need to learn to be specific - you also need to learn to post UNDER
the actual words of a post you are alluding to.
