Power cord replacement suggestions

I second those who say you must experiment; and williwonka has basically 
explained why. BTW there's nothing "fanatical" about better power cords-except the pursuit of ultimate quality by those attempting to provide the best, like MIT Cable for example .If you have 
a system capable of revealing the differences,listen to types of music where increased resolution, refinement and dynamics are important to you,  and if you have a suitable listening environment then -if you experiment- voila !  you will understand. Elementary my dear Watson. 

Chrisr, don't want to start an argument; however,manufacturers are well aware that there are countless power cords better than the ones they ship with. Power cords as expensive as good equipment can be such,that if used with high enough quality equipment,get the chance to show their value.
For example my MIT Oracle AC3 is a non-networked power cord that will literally 'blow away'
standard p/c's shipped with even good equipment.
In a similar vein, some may argue that 'cotton is cotton' but; anyone in the industry would scoff at that comment. The fact many people don't know the facts doesn't change the reality. I hope you won't buy the '100% copper means it's as good as it gets".
