Ozfly, increased inductance on a power cord has its' ups and downs. As inductance is increased, you obtain a natural amount of high frequency roll-off. Kind of like a "low pass filter" that lets the low frequencies "pass through" and attenuates "hash" somewhere above that point. Obviously, the amount of attenuation, cut-off frequency and rate that it slopes off at will vary with the total amount of inductance for the entire run of wire.
While this may be a good thing for power cords due to their limited bandwidth, it is obviously not so good for speaker cables or interconnects. That is why most of the "high end" cable designs are of limited inductance. It should be pointed out that the "roll-off" of an inductive cable can be put to good use if you have an overly bright system. That is walking a tight-rope though, as too much inductance will dull the system out and not enough will still leave you with too much brightness. Better to fix the problem than try to band-aid it. Sometimes though, band-aids are all one can afford at that specific time : )
As to the bad part, wires that are higher in inductance act as a more efficient antenna to RF based signals. It is easier to "induce" stray voltage into them. Obviously, this can be a bad thing if you live in a densely populated area with a lot of transmitters ( cell and cordless phones, AM / FM / TV broadcast stations, CB's, Ham Radio's, etc... ).
The method that Audioengr suggests should theoretically offer benefits over some of the other methods mentioned. However, it would be a lot more work than what Bob suggested and tough to predict whether the results would be worth the extra effort under real world conditions. If one were interested in putting forth that much effort, there are ways to achieve even better results. I don't want to go into details here for specific reasons though : ) Once again though, whether the results would be actually audible or simply more "icing on the cake / increased peace of mind" would be anyone's guess.
If one wanted to get REALLY serious, they could actually measure the total impedance of the run, break down the measurements into specific LCR ( L = inductance, C = capacitance, R = resistance ) characteristics and then create a tuned trap or bandpass filter by adding additonal parts. Something like that would not really suffer from current limitations ( if done properly ) and would benefit everything plugged into that line. Obviously, this would be the optimum way to go but also ( by far ) the most involved.
The bottom line on all of this would simply be a "blacker background" and "increased liquidity" from my experience. Sean
