_power cable_, the one you plug into wall socket - thats how you recognize audiophool scams. You maaaybe could claim some speaker cables are better in theory, but then no one cashed out Randi foundation 1Mil for coat hangar speaker cable challenge

The problem with this is that it's way too easy to to tell the difference between power cables. Even non audiophiles can hear the difference. This is also 15 years ago. Manufacturing has taken such a leap between then and now that even if it was in doubt then, it's certainly not now. Now it's simply a matter of taste, and the better way to represent the reality of cables is that it's subjective, they do sound different, and even though everyone has their favorite cables, no one can agree on what sounds good, much less what makes them sound good. But in general, an better cable will sound "more agreeable" to more people.

I also agree there are a lot of garbage overpriced cables.

I think it's important to remember cables are not measured under appropriate loads, and they aren't measured connected to real equipment.

The measuring equipment falls far far short in the Audio world. Take for example the Audio Precision APx555B. It's the best audio analyzer in existence, and if you go to audiosciencereview, there are now DACs that have measurements that are below the measurable threshold for this machine in certain regards.

Power cables are the same. Not measurable in a meaningful way.

You wrote a lot of nonsense. Randi was willing to pay $1mil to Anybody able to tell the difference between normal speaker cable from Circuit City vs audiophool product. Nobody EVER took the challenge.

Saying Power cables are also better, but just not measurable puts you square with the rest of magical scam audio crowd.

I spent 10 minutes looking for how the challenge would be set up. I couldn't find the requirements. Seems like publicity stunt that is uncashable. Have you seen the terms and conditions?

Would be very interested in them. Seems like Randi is straying out of his lane on this one.
