Urgent Help: Wire for dedicated lines???

Bob Bundus, there's something I don't understand about the homemade power cable. From what I understand the (+) and the (-) are twisted so that the interference cancels itself out. Now what is to be done with the ground cord? Use two wires and twist them separately too?

So if the twist of the wires is in the same direction then there's no common mode rejection, correct? Why twist them, then?

I'm not being argumentative here, just want to find the facts.

Bob, this subject of not feeding power amps through power conditioners is questionable. I figure the conditioner must be properly designed to start with.

I have a Tice A/V Solo and it has separate filtering for power amps. For larger power amps George Tice has a high current model devoted to amps exclusively. I am using a high current(though only 50W) dual mono amp with 6dB headroom and the A/V Solo does improve the sound without choking dynamics. The amp sounds better through the Tice. Bass is tighter and highs are smoother on transients. Noise floor improves. Now if someone's using one of those Monster Cable power strips or similar then that's a whole different story.

I have been reading in the TNT Audio forums that in European countries some apartment buildings each apartment is being installed power filters in their electrical wiring. Under such circumstances shielding the dedicated line would be important to keep the filtered current from getting any more noise. If I were to set up a dedicated line I would definetely place some filtration at the beginning and shield the line. That's why I asked about the twisting in the beginning.
