My first gold cable was the Stealth Pure Gold Signal. It certainly was different from the silver cables I had had, such as the Kondo and several others. I ended up trading it for the Indra amorphous wires, which were much more realistic and less smeared. At some point I tried palladium wires. They are totally worthless in my opinion with no dynamics.
Next I visited the maker of Jade cables to decide whether I wanted the Gold or the Vermeil or gold on silver wires. There was no question in my opinion, the Vermeil were more real and less smeared and lifeless. Later I bought the Hybrids and never really could decide whether I still preferred the Vermeil or them.
I certainly have not listened to all gold cables, but I certainly will not seek them any more.
I think the main benefits of the Synergistic Research cables is charged cables and I must say that while I gradually introduced more and more into my system, each with an added benefit, it was the last that really consummated the outstanding sound.
I doubt, however, that any one of our personal opinions transfer to others. There probably is something going on when a large number agree, but even that is hazardous.
