Which of these power cords ?

Signal Cable!

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.

That can’t be the case for those who initially doubt that a different power cord would make an audible difference. And many audiophiles start out as skeptics, so there’s obviously another mechanism at work here.

... 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.

Now that looks like an extraordinary example of confirmation bias. You seem willing to accept the claim at face value, rather than listen for yourself.

Incidentally, on what do you base your suggestion that McIntosh "is saying their power cables do the job just fine?"

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.

Curious if Mc uses their stock cords in audio shows...
