IMHO the simplest way to test it is simply use it is use it in your stereo setup and see. IMO, consider yourself lucky if you can hear no differences, since you won't be spending all the money on cables like those who can hear a difference.

If they do make a difference, the first thing I would check is the power supply. I'm not satified simply knowing that it makes a difference, I like to know why. That is why I made the suggestion and it is only a suggestion.
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.
