Anyone replace ceramic caps with film?

Looking to replace some tiny generic ceramic caps with an Amtrans AMCH polypropylene film. The value is 220pF, so I haven't found many audio-grade choices in this range.

I'm _assuming_ almost any upgrade from a generic Mouser part to an audio-grade one is worth it, but anyone done this can tell me how it sounds?

I have been using WIMA caps when space permits, don’t think they are "audio" grade, but very good. OR silver mica?

.22 cap? There is a ton.. MPW are in MC225 they last about 1000 years. Teflons last 500 years and Russian surplus PIO will last 100 years. Take your pick. :-)

Bumble Bees. Were good, then Mac bought a crappy batch with acidic paper.. Black Beauties 100 years. Ceramics a long long time. WiMa great caps. 2% are hard to beat..

Agreed, you need to understand the application.  

As general rule of thumb, if in the signal path film is superior to ceramic, and of course there are numerous types of film caps...
