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.
