In the past I've always used the large Panasonic P series polypropylene film caps (not metallized film) for the PPA bass boost cap (C7). While this technically was the superior cap type, the large size made it a hassle to implement in many cases.
Recently I ran across some nice WIMA metallized polypropylene (MKP2) and polyester (MKS2) box cap parts offered by Mouser that will fit the PCM5 footprint nicely. I ordered both types, since for the polypropylene 0.22uF was the largest in-stock item they had which is slightly lower than what I'd like, and the only suitable 0.47uF parts in stock were the polyester ones.
I am wondering... will I hear a noticeable sonic degradation going from the nice Panasonic P polypropylene film to WIMA metallized polyester? Strictly the polyester caps are sonically inferior but this is in a bass boost application, so I'm wondering if differences in quality of caps are as relevant.
Has anyone tried both types?
It would be awfully nice to be able to just pop in a PCM5 box cap instead of trying to creatively mount a huge epoxy coated cap and not worry that the sound is noticeably inferior... Any help would be greatly appreciated! Thanks!
