At the risk of incurring a personal attack, I wish to report that I
have tested common commercially-available capacitors, looking for the
resonant frequency (frequency at which the device's impedance bottoms
out; the cap stops behaving like a capacitor above this frequency and
starts behaving like an inductor). The lowest resonant frequency I
found was 5.3kHz, well within the audio range.


What was the capacitor value for that measurement?



..... and what type of cap ?
