Capacitor audibility: fact or fiction?

The Placebo Effect

I've had preference for mylar midrange and tweeter crossover caps
since the late 70's. They sounded louder and clearer than bi-polar
electrolytics of that era. I knew the mylars have lower ESR than
electrolytics, therefore louder sound. Someone told me that
electrolytics can alter the +/- symmetry of the audio waveform.
Low ESR and good +/- symmetry of mylars were enough to make a
believer out of me.

Those are exactly capacitor impedance measurements. Sorry, I cannot reveal exact setup as this involves trade secrets. I can only encourage others to try and understand the detail structure of capacitor, and the charge and discharge characteristic, and find an appropriate method.

The two that look alike are different caps, but sound very similar, as it was the goal as explained. Other than that, I can't reveal any more. By now, I though the whole forum would know what I use for testing.

The story is we found a cap that was sonically very close to the Duelund silver gold, found the supplier, asked for samples and found they did not sound right. So we had to prove they were not the same.

Out of curiosity, what's a Duelund Silver/Gold?
