This is the same sort of deductive reasoning that apologists use to explain the supernatural. Just because a bunch of other fools believe something it doesn't mean they're right. It means they were all fooled. Your logic is very flawed and I don't think you understand how electricity works. This power cord thing is utterly ridiculous. Clearly, you've been indoctrinated tho, so I'm not even going to waste the energy debating you. I believe it would be fruitless and an exercise in frustration.
I will say this tho, people who believe they can hear a difference have never done a proper dbt, and the ones who do always fail. I wish I knew you, I really do. I have all kinds of stuff I'd like to sell you...
