The onus is on the reviewers (And manufactures) to show verifiable evidence so that anybody can check that the claims are correct, (Check your old school science books to see how to use it) not the other way round.Bill,
Please show your testing methodology for this cable and show verifiable evidence that the claims are false.
The easiest test is the level matched double blind test which removes any bias and placebo effect.Salty. Standard psuedo-intellectual response of course and a tacit admission that you've neither tried nor tested this cable.
Actually, the onus is on you to disprove, as you don't have a gun to your head forcing you to read the review nor buy the product. Maybe brush up on your understanding of capitalism...
