Further to the ClarityCap resonance study, I'll add that listening to a low-resonance capacitor-- or a low-resonance wire, assuming that this is the purpose of the oiled silk jackets on the Duelund wire-- can take some getting used to. Once the microphonic "excitement" is gone, one needs to evaluate whether musical information has gone missing as well. IMO excessive soft damping in some types of PIO caps can have both effects, in addition to causing shelving effects throughout FR.
Audio has alternatives to deal with mechanical resonance(e.g. soft vs. hard damping, coupling vs. isolation). Each approach may have its place. Moreover, damping properties of materials vary independent of dielectric properties. Teflon, for example, which has excellent dielectric properties, is relatively soft, which may be a good or bad thing with respect to resonance control? FWIW, I can report that at least several leading OEM designers don't like the "sound" of teflon as compared to polypropylene. But what properties of the construction are they really hearing? There are multiple variables in operation.
It's good that the inclusion of V-Cap in the discussion seems to have moved the thread beyond the paper vs. plastic discussion.
