Which of these power cords ?

That's a quote from a Mc source.

Cleeds you're free to spend your coin on the cable. Until I see an independent review showing that there is a real need to spend on one, I'll stick with the manufacturer's recommendation.

Has there ever been any lab testing on power cords by an independent lab? Something where SCIENCE can confirm these costly cables are actually doing something? Otherwise, I would wager that those who spend the coin have a problem with confirmation bias. It's your money...go ahead and spend it how you wish, but if McIntosh is saying their power cables do the job just fine and that your better off buying music etc., then that's good enough for my ears.
