Too bad some are really out of it. If you, Crafts and Skeptic, understood what DA and DF meant, you wouldn't have made such stupid comments.

DA is the most important of the two, and is the slow release of electrons from the insulation when discharging or reluctance to accept electrons when charging.

Instead of discharging and charging perfectly, the incoming note, say bass note, there is a slower release, causing a distortion (not harmonic or intermodulation distortion that is typically measured) of the note. This is Physics and can be measured. This causes the note to sound fuller, extending longer, Not an actual change the amplitude as you would try to have us believe.

One can easily do ones own test by simply purchasing two capacitors of the same UF, one electrolytic/bypolar, and one polypropolene and inserting them into a circuit. I don't think the public needs you twos permission do they???????? Let them decide or are you afraid of what they might find out??

As mentioned before, in audio subjective testing, DBTs are worthless. Scholars themselves won't use the terms "factual" or "proof" only "indicates" or "seems to indicate". Hardly factual.

Get back to reality.
