    Na örülök, hogy végre van valaki, aki tíz paraméterből megmondja, hogy fog szólni egy kondi. Van itt ez a vicces kísérlet:
     
    ... the same as we have found, that AC signals are electromagnetic "shockwaves". I think that there is more to that most audio enginers realize. To give you an example, when I started looking at capacitors , we devised the following test:
     
    Connect a capacitor over the output terminals of a stable  power amplifier, then connect a frequency generator to the input, and set the volume level at about 1/4 to 1/2 volume. Then run a frequency sweep from 0-20kHz into the amplifier. All the plastic capacitors that I've tried sounded like a small (very small) loudspeakers, the paper caps were almost silent. We employed sensitive listening devices like medical stethoscopes for these tests. The frequency at which a capacitors resonates under these conditions closely matches the colouration it introduces into the sound of the amplifier when used in the signal path.

    Akkor ez melyik kondi paraméterhez rendelhető egyértelműen?
