Best Male & IEC plug for high current power cords?

I have found unshielded pc sound better with tube amps.
Copper power wall plugs have more realistic bite than silver.
Silver power wall plugs sound more organic on voices.
I made some unshielded power cables with copper wall plugs and silver iec - but they are not optimum for my digital equipment. AND, I am not convinced they are optimum for another tubeamp. It is quite frustrating to figure out what to use. I also have a sense that wattgate may sound a little bit better than furutech on both copper and silver.
Check out "power cable shootout" and good luck.

I am sorry as I am way late to the party here.. but the wall outlet? Why stop there? What about the romex feeding that receptacle? And how many receptacles are on that circuit? And what of the quality of the romex? and the circuit panel box, what about the quality of the breakers in the panel? (silver or copper connections?) And then the feed in from the meter on the side of the building, and then the wire running up the masthead and the connection that the power company makes, with their heavy use of electrical tape and then the feed from the transformer on the pole? and the transformer, and the step down circuits.....and.....

Well maybe you get my point... Am I the only crazy one?

hello... hello... or maybe it is just me and I don't know what I am missing. :-)
