The Sound of Capacitors - Ceramics

I reported two types of ceramic capacitors, one a 100 volt Z5U part, one a 1000V Z5U. To this I will add one additional part: the ubiquitous monolythic "digital logic" bypass capacitor. Here's the results:

Notice that in the last picture, in addition to the non-linearities at the ends, theres another "kink" around the zero crossing point, adding yet another delightful characteristic to the sound!

In fact, there's yet a worse characteristic to these type of capacitors: their characteristics change considerably with frequency. Here's the data at 600 Hz and at 100 Hz:

Notice that there's hysteresis, "saturation" and odd kinks present in the curve. Just to prove there is no systemic setup problem, here's the characteristic of the mono at 100 Hz, and an oil-paper also at 100 volts:

Nope: it's the ceramic doing that!
