i came across an article that compared various capacitor dielectrics and how they affect sound. Polypropylene was the clear winner, and PIO.
This was not a "listening" test. It was an objective test done with test equipment that displayed the distortion created by the different dielectrics. A testing methodology you can believe in, rather than people with expectation bias skewing the results.
At that time, polypropylene caps were harder to find and more expensive for reasons I cannot fathom, and now they are much more common and more reasonably priced. Since polypropylene is a cheap common plastic, to my thinking they SHOULD be cheap.
Tantalum tested poorly.
The Trainwreck guitar amp uses I believe a ceramic cap paralleled with another more audiophile quality cap to supposedly get distortion, more "crunch" as the guitarists call it. Of course, you would not want this in an audiophile amp.
