From an electrical engineering standpoint, there a few problems with the arguments.
First, lowering cord resistance does not lower the currents. On the contrary, it would increase them according to Ohm's Law since you state the voltage differential is between the amp and outlet - surely an error in logic here. Second, for the cords to eliminate the differential voltages, there would have to be a special LC filter involved that dissipates to ground - which is not the case since a cord is a cord (however, perhaps MITs do?). Third, if the power supply is any good, the differential voltages will be miniscule anyway and the error will be taken out of the amps, and not the cords, since they are the only ones that can sink the difference effectively. Thus, the cord does nothing to help here either.
The biggest effect a cord can have is shielding (and definately not filtering as the argument states) from EMI which is present for sure in bad power supplies. I beg to differ with the cord designer but he is also a business man. I am an electrical engineer that deals with these sorts of things daily doing research on high-power power supplies and so have to be very sensitive to these things. The cords don't do much but shield as I said above. This may account for the sound differences people hear, and then again, it may be psychological (I am dodging the tomatoes ;).
There will be differing opinions on this but mine is strictly from a technical viewpoint. I can fill in with great detail for those who wish to email me privately about it. Arthur
