ERO KP 63V 5.6nF Polypropylene vs RIFA 200V 5.56nF Polystyrene

[LosNir]

Hi. I ordered both capacitors from 41hz:

1. 41Hz Audio:Cap 200V Foil 5.56nF Polystyrene
2. 41Hz Audio:Cap 63V Foil 5.6nF Polyprop

I want to use them in a 'James' Baxandall Tone Circuit. The value should be 5.6nF.

Which is better? Thanks.

Polystyrene Rifa easily beats almost anything, including Ero PP:

So I should solder the Rifa?
By the way, both are foil, not film.
