I also made the suggestion to bring the attention back to the actual purpose of the power cord. Most people look at electronics like they are a magical device and don't have the first clue how they work. On this site, I think most people have an above average understanding, however, there are still parts that people seem to gloss over. Power cords seem to be one of these parts.

The purpose of a power cord is to deliver AC power to the PSU. That is it. If two cords sound different the PSU output is different in some way 100% of the time, no question about it. If you can prove that a power cord can affect a PSU first, then answer the question what it changes, you will then be able find better ways of fixing the problem without resorting to cryogenic freezing, rare earth magnets or magic dust.

I do agree that using it in your own setup is the most simply way, but it isn't the most accurate, it won't end the debate. If you aren't interested in testing in this manor, that is fine. But, because of the reasons above, I think it is a valid and extremely useful thing to test.

I mean, imagine how easy it would be to prove that they make a difference if you hook up 2 different cords and find out they cause the PSU to produce a different voltage? Nobody would be able to say you didn't DBT properly, or anything like that because you could easily repeat it and don't need to worry about sample size, variance, or any statistics.

I highly doubt it would be that easy, but that doesn't mean people can't start looking at it from this angle. Please don't dismiss my idea.


I'm not really dismissing your idea, but I'm feeling that it would be even more difficult to match the numbers there than testing it on audio equipments.

I really don't agree with the accurate part of your post, IMHO accuracy in this regard is depending on the user of the actual equipment, ie whoever bought it and use it at home.

If you are going to test power cables on PSUs, do let everyone know how you are going to go about it, since the setup alone would be rather interesting and complicated. I'd love to know how it turns out, even tho I don't think the result is going to reflect actual effect on stereo very easily.
