I've only had a quick look at the above, and the pages linked to it.
However they don't seem to me to be particularly relevant to the
question of capacitors normally having a 'sound' in normal use.

I was trying to provide information relating to the "I see objective
measurements that indicate that there should be a difference" part, not
the "sound" as such.

Ah. So you point was that types of capacitors may well differ in ways that
we have no particular reason to think have any effect on the audible
results when they are used appropriately in audio equipment? :-)

Serge: Was what you wrote above intended to be dealing with that point? I
read the above to mean "objective measurements", etc, that support the
argument that they would lead to a "different" sound in use...

Slainte,

Yes indeed. I asked if there were any measurements available that
indicated that an audible difference should be apparent, i.e. that
passing a signal through one type of capacitor had more noise or
distortion than another type. The oscillograms on the "sound of
Capacitors" page were of capacitors under conditions that would not
normally be encountered in audio circuits, and made the leap that
because some capacitors had curved oscillograms they should sound worse
without giving any reasons for it, only that they should. No
measurements were provided to support this point of view.

As mentioned earlier, in my design days, I was never aware of any
increases in distortion that resulted from capacitors in circuit, even
using electrolytics and tantalums (tantala?) provided they were well
polarised.
