Of course you can. By looking at these properties or even use measuring tools to give quantitative results.

The capacitor sound guys choose the prettier girl by the price tag at the girl's door, without even taking a look at her nose, her eyes or her weight.

Nope caps are very different actually.

A gold foil cap would sound much better than a silver metalized film one. And yes inverting implementation of an opamp is more popular "en mass" because proper non inverting schematic requires a decoupling capacitor that is often pricer than a opamp itself.

Most SS owners would consider metallic tweeters or full range like Fostex or Klipsch "too bright" or fatiguing. But tube amp owner with foil caps, chokes and no global NFB can enjoy same speakers.

Based on what theoretical principle, given both caps are manufactured to the same electrical properties and tolerances?

Because gold looks nicer? Or because it is pricier? Why not platinum? What's wrong with copper or aluminum?

EDIT: I missed your distinction between gold *foil* and silver *metalized*. If that's the point, you should say foil caps sound better than metalized ones. But even then: Which one will sound better if both use foils?

Right foil caps do sound better. However Black Gate claims some of their electrolytics were as good as. Personally I found out that Mundorf's silver oil no good just waste of money Epcos PET performs the same. Duelund Coherent are great (I am using just copper ones but silver no gonna spoil them either) sounds like plain wire. Even Soviet K40-U9 is right stuff.

Silver wounded MCs or OTs vs copper not quit sure. I do believe they should be equal in performance as well.

WBT 4% silver leaded solder is real pleasure to use. Never used gold contained solder from WBT but it might improve rigidness of joints.

If it cost more and is made from a more expensive element they will come! If I tell you mine is hand wound by virgins you will pay more. If I say because I say it sounds different that must mean it is superior or inferior, that is the suggestion here. The rolling of capacitors and the inane suggestion that the more expensive brands sound better are great if you are the one selling them, more power to them in taking away money from foolish people who want to believe. There is no proof to any of these comments made about gold foil or anything else except I say it sounds better comments. I bet not one of those are based on measured results, just again willy nilly changing capacitors and seeing if you can hear a difference. This subject is just a joke, not one real scientific based study is sighted, just anecdotal things said by marketers and salesmen selling snake oil. This is no different than people randomly changing op amps and saying one is superior to another when each op amp is not optimized in a circuit, it is very poor science and not really good information in any regard.

Clears reproduction of timbers without extra coloration.
Film caps are on bright site, average electrolytic cap is a bit dull.

if you had tried Duelund Cast Copper Cap, you wouldn't need to be talked to believe in how much a pair of caps can improve a set of hifi

I would have thought it is obvious: if 'genuine' caps really do improve the sound in the clear way that some people say then surely a 'fake' cap will degrade the sound or leave it unchanged?

So there is no problem. Those of us who are not true believers don't buy those sort of caps anyway. Those who are true believers can detect (and thus avoid) a fake just by listening to it. Everyone is happy.
