Bol1972,
Don't forget to stop at my house! Actally, I don't doubt that what you are saying about power cords is true; why would you make it up? The problem is that most of us who have 2k or 3k amps can't afford 4k cords, and those of us who have amps in that price range can't justify the value quotient of a cord that expensive, as opposed to a complex piece of electronics of the same price.
One more thing, and I am not trying to poke fun at your English, because I wish that I was even slightly bilingual, but I wanted to point out in a friendly way that you often say "overwhole" when you mean to say overall.
I do enjoy your posts.
