What an odd article. Most of those 'misconceptions' I have never heard anyone say before and seemed contrived to create an article. I certainly have never heard anyone describe electricity as water before. The misconceptions about external EMI and manufacturer designed power supplies actually seem like arguments against high end power cables. As to component generated EMI surely all the points the article raises are mitigated by well designed equipment that has a decent power supply and effective shielding/screening.

The article actually makes me even less inclined to believe in the benefits of aftermarket power cable rather than more. Which considering the article originated from a manufacturer of power cables and starts with the premise that aftermarket cables make an obvious improvement to both audio and video is quite an achievement!

Whilst I realise this is not the intent of the article but what it lacks, like pretty much everything else I have read, is a clear definition of the problems that need fixing and an explanation as to how each of those problems are addressed together with a comparison as to why fixing the problem in that particular way is better than fixing it by other means. It would also be nice to see an explanation of why the problem needs fixing in the first place since I am not always convinced that some of the issues being fixed, although they exist, are actually a problem.

My simple uneducated take away from the article is to buy decent equipment and as long as the power cable is properly constructed not to worry about it.
