...it should be understood that the article is 35 yo and there have been cap technology improvements and style and fashion changes since that was published as well as other studies with somewhat contradictory findings. The Marsh and Jung article doesn't even acknowledge a current cap darling, the hermetic PIO. Another cap cap type currently in vogue, the silver-mica is found to be substandard by them. The article also equates film-n-foil construction with metalized film and yet today there are many that believe film-n-foil to be far superior. Another oft cited (but old) "cap study" by S. Bench finds the PIO type to be superior to all other types including the polystyrene types that Marsh and Jung find to be superior along with polypropylene and Teflon.
Overall, it seems that one still can't generalize about caps in audio apps except for maybe high value ceramics and tantalums. Caveat emptor for sure.
