There are: 1. gold cables 2. gold alloy cables 3. cables plated with gold, so technically there should be several different discussions if we want to compare apples to apples.
The Gabriel Raptures (which I have tried and like very much) fall into categories 2&3.
Gold plated cables can be alloy, silver, copper or some other metal. Thought it wise to point this out only to clarify the discussion.
BTW: There may be other configurations I haven't thought of.
