"one of the big differences in sound between different plastic films (eg, mylar, polypropylene, Teflon, etc.) is due to the mechanical properties."
Hmmm, didn't know that and I've used a lot of them over the years including stuff likely as cranky as audio. Seems like most of the time the issues were dielectric absorption and ESR and maybe TC. Always something...
"Another thing that affects the sound of film caps significantly is how tightly they are wound."
Well, I guess that makes sense, especially if tighter is better.
You have a lot of interesting insights, glad you are posting more. Let's see what can I add? Well, I bet you've never ran a wrapped polystyrene cap through a vapor phase degreaser!
It turns into an air dielectric cap that shorts really easily.
