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!

Many cables and cable mfger's design their cables for specific application. How many times have you read that a cable worked great on a DAC, but wasn't as impressive when used on a amp or P/conditioner

Low level and digital componets would have slightly different requirements than high current (amps) and power conditioners. Low level and digital componets seem to like shielded cables that are very linear. They seem to like very stable (linear), noise free, current. Amps and P/Conditioners on the other hand are less fussy about shielding and seem to like larger gauges to bring in more current. The power supplies in Amps (if properly designed)with bipass caps or filters, and their rectifying circuts can handle the on line noise better, so may require less shielding. P/conditioner by design are supposed to be able to eliminate most on line noise. Funny thing, how many times have you read about a P/Conditioner being improved by the power cord feeding it.

Just check out some of the PC cord mfger's, Elrod has a EPS2 for low level and a EPS3 for high current, JPS has various models and some specific for digital(probably has a small shunt filter from the neutral to ground) Shunyata and CH Venhaus also make application specific cables and check out Wolff Cables who makes a different source and gain cable with a carbon shield.

One other cable mfger I would like to mention is Essential Sound Products. Their cables work equally well on source and high current (one cable fits all) and this has been commented on in a number of reviews in the past.

Do you still have that silver and black 1957 corvette???
