The Truth About Power Cords and there "Real" Price to Performance


This is a journey through real life experiences from you to everyone that cares to educate themselves. I must admit that I was not a believer in power cords and how they affect sound in your system. I from the camp that believed that the speaker provided 75% of the sound signature then your source then components but never the power cord. Until that magic day I along with another highly acclaimed AudioGoner who I will keep anatomist ran through a few cables in quite a few different systems and was "WOWED" at what I heard. That being said cable I know that I am not the only believer and that is why there are so many power cord/cable companies out there that range from $50 to 20-30 thousand dollars and above. So I like most of you have to scratch my head and ask where do I begin what brand and product and what should i really pay for it?

The purpose of this discussion to get some honest feed back on Price to Performance from you the end user to us here in the community.

Please fire away!

Delkal,


I have been respectful to you but your attitude is poor and your knowledge worse.


The AC supply is a voltage at 60Hz. However the frequency of the power draw, i.e. current, is a factor of the load effectively modulating the line frequency. Hence you have current draw both at 60hz, and at many harmonics of 60hz, primarily odd harmonics the spectrum dependent on the load.


I will emphasize again a linear supply cannot work if it draws power only at 60hz and you are confusing supply voltage frequency with power draw frequency. The lack of knowledge is not mine, it is yours. (Note I said that it draws power 120 times per second not that is the primary spectrum of the energy draw). 


Short of a resistive load just about nothing on the AC line has low distortion. 


It would not be unusual for a linear power supply in a piece of audio equipment to be running 30% or more harmonic distortion on the AC input current. Only way to fix that is to add resistance or inductance to the AC input lines.

...the #1 lesson that an audiophile can learn is that they are susceptible to bias.
 
What I can't stand is those who say my evaluations of my system upgrades are so heavily biased as to be unreliable, or even delusional.

It's beginning to look like it. To the point of me starting to detest is, as only [the slayers of snake oil] use it, in every audio forum they can find.
There are members I detest, and whose comments I no longer read.

"They both do exactly the same thing on the same circuit. I don't think you have thought this through. Of course they have the same importance."



Good plugs are off course what everything relies on, but the male plug at the end of a pc is not where I would put my money.The female walloutlet is the one that might makes the difference.
-------------------

Think again. The male is just a passive plug, just keep it clean while the female is all about how tight it wraps around the male and makes mechanic contact.
