Power Cords - Shielding or No Shielding


I have been researching power cords (PC) this past week and I must say, I find this far more frustrating than researching any other part of the audio system.

It may be a false hope, but I desire to purchase a "generic", if you will, PC that works well everywhere, I can't say now what piece of gear it will be on and even if I did, that piece may change at some point. I suspect some will say that just like other gear plan on changing as necessary; I am hoping not to do so. Anyway, I am getting off topic.

Most PC's I read about have shielding, but Audience claims on their Web site that they do not use any on their PowerChord stating, "The powerChord by audience is not shielded. We have found that shielding power cords can be sonically detrimental." More can be read here.

What is the collective thought on this?

As if the cost of interconnects and speaker cables weren't out of control (IMO), PC's are right there with them. I have already doubled the price I started out to spend and it's going up!

Brian, welcome to the somewhat confusing world of cabling. I think much of the confusion is actually introduced by the manufacturers themselves. If you compare let's say, 10 different cables, by 10 different manufacturers, they will all have their own "proprietary" way of doing things. A lot of these "proprietary" ways are actually procedures that almost all manufacturers are using.

As you read about shielding, you must first determine the reasons said manufacturers are shielding. Some manufacturers shield for RFI/EMI rejection, some shield for field suppression (an electrical field created by a conductor passing current). And Yes, if shielding is improperly utilized, it can make for a sonically "dead" sounding cable.

There are very few manufacturers providing sensible reasoning as to why their design/manufacturing procedures work. They just simply state that they do in fact work and provide the "best sound". What the hell does that mean?

I come from an engineering background. It is very hard to sell me on how things work. I need to know why. It's a personal issue I've learned to live with. I'm going to refer you to a site that I have referred many people to. I am referring you for one reason, and one reason only. It makes sense.

This is my own personal disclaimer: I am not referring you because of any specific brand. I am referring you because the reading although somewhat brief, is quite interesting. It is probably one of the only manufacturers that cuts through some of the crap. I'm sure that there are certain manufacturers that would prefer not to have this type of information disclosed.

I hope this helps and provides some additional insight.
