I certainly don't like the wire gurus or their websites, but I must come to their defense here...
If a wire gure claims that "you can't prove a null" they are telling the gospel truth. You can't. Not possible. And not proper statistics. You can reject the null, you cannot prove the null. The problem is thes goofy cable gurus aren't supporting their argument any by making such a claim.
Basically what they're saying here is "We're not going to prove to you there is an audible difference, instead we're just going to tell you that you cannot absolutely, with 100% confidence, prove that there IS NOT an audible difference."
As you've suggested, it is the seller's burden to provide proof, not the consumer's.

Great thread!
