This is THE powercord I want :

Redkiwi, I may be wrong here, but do you not think that the power cord material is just an extention of the power supply and is subject to the same improvements that say an Audio Note silver wire wound power supply and its benefits to that line of Amplifiers? In other words the better the copper, the more it will benefit the supply, if said supply is of commensurate quality. That is the way I see it. Even 5 feet will benefit improvements, just as only one link of high end IC, in a system riddled with junk interconnects will yield an improvement. What do ya think Red?.......Frank

Red, so from all your trials, you feel that copper purity is secondary to Geometry and Dielectric? This is particularly important, because if copper purity or silver for that matter IS down the line,in importance, then this is a huge savings moneywise. I am with you on this as far as ICs go,ie; that a cable produced with great design and dielectric parameters AND mundane copper, will outperform one that has the highest quality conductors and lesser design. But, I never knew if this applied to PCs as well. Thanks for the help..........Frank
