In Reply to: Re: SCD-1 owners...what is the Brand and model of the stock power cord? posted by zako on April 22, 2007 at 11:37:09:
As I understand it, the reason for improved performance with better powercords is that most stock power cords emit RF interference. The result is a magnetic field in and around the cord that can affect nearby components. The better cords have more effective shielding.
Perhaps some of the engineers on this forum can give a better explanation.

zako is a power cord naysayer. Despite numerous attempts by others to provide him with information that counters his beliefs, he continues to post his "power cords are a scam" diatribe on a regular basis.zako has made up his mind, and is not interested in opposing views or data.
Sure I,m interested in opposing views...IF they work...But so far my impericle findings show the opposite.
If your gear or your ears aren't capable of displaying or discerning a difference, that's fine; however, single data points are pretty much worthless when it comes time to make solid judgments. Assuming that your experiences are applicable to everyone else is foolish.I hate to say this, but given the extremely limited parameters of your "findings," your running around declaring that upgrade power cords are a universal "scam" and that they can't work just makes you look narrow-minded and silly.
You say you are interested in opposing views, but every time you have posted your "power cords are a scam" diatribe, you have complete ignored anything anyone said that gainsays your opinion.
I would be very much interested in the data you reference.

Out of interest, what data supports the notion that power cables make an audible difference? All I see are lots of test that prove the opposite. A few links would be great. Thanks!
Some links please.

I have never seen any credible science that either refutes or supports the merits of higher-end power cords. Articles I have seen in audiophile magazines almost always support their claims of improved sound. Articles that tend to refute claims of higher-end power cords that I have seen are found outside of the audiophile press. An exception is the "Audio Critic" that has taken a clear position against expensive power cords. An "Audio Critic" article link is below. But again their stance is taken with out the benefit of science.

My two cents. To say power cords do not change the sound of the equipment that it is connected to is crap, anyone can hear it.
Having said that, in my experience power cords are a crap shoot, you never know how they are going to work on a given piece of gear and I would say the audiophile press has never given a clear outstanding of why this is so. Though they now are backing away in reviewing them and I think is is due to a lot of issues.
I think just like speaker cables you are dealing with a lot of variables, impendence, how the power supply reacts to the cord etc. Even the manufactures stay away from proving why there cords are better then the next guy’s cords.
I have just received a few new power cords and none of them sound the same and anyone in my house could hear the difference in 30 seconds.
One is warmer, one is fast and brighter sounding and one is right in between with a slight roll of at the top, one sounds great on my cd player and so-so on the amp but good on the pre-amp.
So anyone who said they cannot make a huge difference is not of this world, the problem is its a crap shoot, no reviewer can tell you how it's sounds, you can only say how it sounds in your system, the next guy may have a totally different experience.
I do think sound of the power cords are crazy priced. No cord should ever cost more then a piece of equipment, I have looked inside many and it’s just wire! Do I think its snake oil and BS? Yes some of the time.
But I think the cable designers all know, no matter what power cord you hook up it is going to sound different then the stock cord or any current cord you are using, so they are in a no lose situation. So yes the sound does change and that is a fact Jack!
This topic has been beaten to death on AA (and is currently undergoing a similar beating here in this forum). There are plenty of threads on this, and some interesting information from people who have done measurements. The AA search feature is your best bet.Now - you say that there are "lots of test that prove the opposite." What tests are those, how many is "lots," and what exactly did they prove?
