Cap materials having different tone hasn't been proven false.
Cap materials having different tone hasn't been proven false.
The data and sound clips above show clearly that for tone capacitors of close measured capacitance value there is no difference in tone. For example, compare the clips and plots for the “Monolithic X7R 0.022uF – 0.0204” and the “Vishay 225P Orange Drop 0.022uF – 0.0204”. (You can click on the colored box in the legend and the line will be highlighed briefly.) These two capacitors, of the same measured value (0.0204uF) but different dielectrics have indistinguishable plot lines, differing in frequency at the 0dB crossing by about 0.3%. This difference is below the rated accuracy of our measurement equipment and is statistically insignificant.
That depends on what you mean by false. I found this comparison of frequency plots of different dielectrics for common guitar capacitors.
I am really glad to see that you can have fun bantering with us, keeping it light, without getting pushed out of shape and getting rude.
Nice show.
Oh drat. I actually have read that study before. I think the percieved differences are stuff that you can notice in person but that doesn't really get picked up by recording or analytical equipment.
I've tried several values of mylar and ceramic and none of them sounded vintage.

Which ones sounded "vintage"?
The paper in oil!
