In this particular circumstance we also have to conclude just what _is_ guilt or innocence, so this is not a 'simple' court case.
Clearly there is no such thing as a perfect cable, so our 'innocent' cable must be less than perfect, but how much less then perfect?
Is 'guilty' a nearer to perfect cable that's just a silly price?
Some cheap cables that are notably less then perfect are 'guilty' because they do give noticable degradation. Microphony and poor connectors, for example.
I'd willingly pay for good tightly constructed low-oxygen cables ith conductive plastic interliners and good gold-plated connectors. I might pay for silver plated conductors, though I suspect the benefit is doubtful at best.
Would I pay for cables at hundreds of pounds/dollars a pair? No way. Not guilty, but neither am I that gullible.
Would I pay for cheap thin cables with pressed nickel-plated connectors for an audiophile system? No. And in that case I think a guilty verdict might well be reasonable.
