Hi Guys
Polester/mylar adds much more distortion than polypropylene, which is essentially distortion-free. Polyester adds odd-order harmonics which will be heard in different ways insofar as these harmonics become part of the input signal to the following gain stage, which distorts the fundamental and all these extra tones, so "fatter" is a possibility. The extent to which the cap distorts depends on the signal voltage across the cap.
If you want minimal ceramic cap distortion, use NP0 or C0G; for maximum grit use X7R.
Within a given dielectric range, the physical size of the cap will effect parasitic elements contributing to tone, as TUT3 states.
