I tried various types of caps when I first investigated the speaker cable filter, and settled on the silver-mica as the best of the lot. However, I did not include metallized paper in that testing.

Since then, I've experimented with AC filters and found that the Wima MP3 are the best-sounding of the rated types. A friend of mine has compared the silver-mica against metallized paper on his speaker cable filters and he definitely prefers metallized paper.

Another drawback of the silver-mica caps IME is that they have magnetic leads. The Wima metallized paper caps do not. The Evox-Rifa metallized paper do.

My only concern with Wima metallized paper is that the smallest value they make is 1000 pF. Smaller caps do improve the action of speaker cable filters.
