Why would you want to do any of those things?  I'm jumping on you Pete for having illogical thought processes for seeking a solution to a problem that doesn't actually exist.

Someone will try/buy an interconnect then it will either float their boat or not as the case may be. That's the beginning, middle and end of the argument.  Pass that same cable on though to someone else and what are the chances of that same result occuring again?  Some may not hear any difference at all with whatever cable no matter what it's made from.  On that basis then, what point is there for 10, 100, or even a thousand golden eared listeners blind testing away until the sun goes cold?

Who always insists on double blind testing cables anyway?  The very same people who won't try or buy a better sounding cable  Good on them if that's their decision.  Those that can clearly hear the differences and are very happy with their purchase never squawk about it because fooling around with cables is part of their pleasure in the hobby. Not just cables, but box swapping too
