Twisted or Straight?

I searched Audiogon for info on inductance and capacitance. From an excellent post by Sean on March 24, he explains that inductance increases with wire spacing ant that capacitance increases as wires move closer together. Therefore, a twisted pair raises capacitance as contact between wires is increased. On the other hand, I'm a bit confused in that I thought winding wire would increase inductance.
Here is my question: For an ac power cable running from the panel box to the outlet, would it be better to run twisted wire or straight (i.e., parallel) wire? Specifically, I'm referring to twisting the hot, neutral and ground vs. having them run parallel? I've read strong preferences for both. Per Subaruguru's post, straight romex increases inductance and allows unwanted high frequencies to roll off. Other posts suggest that twisted is better. Please help me sort this out since I am running dedicated lines to my stereo. Thanks in advance.

Bob,

It's really not that much more labor to run three circuits as opposed to one. I ran the circuits in 3/4" pipe (One to each location). Then pulled the wire, made up the devices, terminated the breakers, test the system and BINGO WE HAVE A WINNER! I actually have room in the conduits to pull more circuits but that sounds to much LIKE WORK!!!

This is really the way to do it. It keeps the grounds pretty much at the same potential and the lengths of each conductor about the same. Ground-loops is the biggest concern when running multiple circuits.

Audioengr,
I've surfed through your website recently.
You've got a huge amount of talk about skin effect.
Can you remind the formula calculating the current density? I want to apply it for audiable freeqencies and see the range of impedance changes.

Thanks!
