Silver-plated or single metal IC's?

Everyone is forgetting one fact, you cannot have copper wrapped with Teflon. If you want Teflon surrounding copper, the copper must be silver plated.

There are cables that are silver plated that have a reputation for being neutral to dark, Purist Audio is an excellent example.

Tvad,
Sorry to be so slow, I've been on location photographing a pharmaceutical plant.

Regarding your question "why" about my post (pasted below):

Everyone is forgetting one fact, you cannot have copper wrapped with Teflon. If you want Teflon surrounding copper, the copper must be silver plated.

Teflon allows oxygen to partially pass, resulting in oxidation. Too, the physical act of bonding Teflon to copper causes corrosion.

Copper oxide is a poor conductor, silver oxide is a good conductor. Silver does not react to Teflon and oxygen passing though results in silver oxide which is a better conductor than copper oxide.

There may be more to it than my short explanation, but these are the two basic reasons.

Here are a few links that cover the topic in a round about way, without resorting to the (easy to find) claims by dozens of cable manufacturers :^)

Permerability of Teflon to oxygen

Dennis, perfect example of how cables plated with Silver are not necessarily bright. Purist is indeed neutral to warm tonal balance and if your system is already neutral to warm it may not be the best match.
