Power cord? Why?


I see a lot of posts regarding power cords. I would like to know what sonic difference they actually make. Could anybody explain this in a simple way?

Thank you

Eldartford:
It doesn't work like that! Mill down #12 to #16 at termination point and you have #16.
Sean - been at HE2003, but I'm back now. Regarding Goertz, these cables make a lot of sense technically. There is no way to get lower inductance than this. Not sure why Roger would be concerned about the amps. They should be able to drive these - particularly given they do not have any global negative feedback. His concern is probably more about the speakers themselves.
Corona: While reducing the surface area where the connections mate will reduce the total current capacity of the cable, the blades that go into the wall and the IEC will melt before the "limited" current capacity of Eldartford's method comes into play. Yes, doing so will alter the impedance of the cable, but not enough to negate the benefits that he sought to achieve via distributed capacitance.

By the way, when are you going to support your claims / comments with some hard information pertaining to makes & models ? We are still waiting....

Audioengr: Hope you had a good time at the show and was / will be profitable for you.

I don't know what to tell you about Mr Sander's reaction to this specific brand of cables. I'm simply going by the information that was passed onto me by a very reliable source.

As far as the Goertz cables go, i assume that you're talking about their speaker cables given the reference to low inductance being beneficial. As you are probably well aware, i'm pretty fond of these as a general rule. Minimal skin effect ( they are ALL "skin" ), minimal dielectric ( new models use Teflon ) for reduced DA ( Dielectric Absorption ), heavy gauge for low series resistance, low nominal impedance for maximum power transfer, wide bandwidth, etc... If people don't like how these speaker cables sound in their system, they need to look at why the system doesn't sound good, not blame the cables !!! As far as ways to improve these cables, all they need to do is get some decent connectors on these things. Other than their Silver spades, their standard spades, bananas and pin connectors are junk !!!

If you are still running the JC-1's and can get away with a four feet of speaker cable, i can send you some MI-3's ( 7 gauge / nominal impedance of 2 ohms ) to check out. I had these running from my Kinergetics KBA-202A Platinum Mono-Block's to my Ohm F's. Since i'm not using the mono's right now, you're more than welcome to give them a try. Sean

Corona...What I milled down was a 3/4 inch length of twisted-together and soldered triad of #20. I would guess this was about #6 in diameter. About 1/2 inch of this I milled down so it would just barely fit into my heavy duty connector...about #10 size.

Sean...Do we have any impedance or capacitance data for the various highly-touted power cords? If not, I don't see any use for such measurements on my supercord.

To all....If you are a Wizard, and are publishing the recipe for a magic potion it is always a good idea to include some ingredient that is difficult or impossible to obtain. (The eye of a newt collected during a solar eclipse on a Tuesday). Then if the damsel does not respond as expected, you can always tell your client that the potion was not prepared properly. This power cord stuff involves a lot of black magic. Are you wizards?
