Power cord length?


If I'm going to spring for an uber expensive cord-a 'final' purchase-say an MIT Oracle AC 2--is there any sonic benefit going to a 4 meter vs a std 2 meter? (I have absolutely no chance to audition). Technical details of 12 ft versus 6 ft power cord?

Hi Mapman, I hope you are correct, one would also need to consider the make and model of the power cord in question, I have a 3ft Tara labs cobalt power cord, you can understand the reason for my post above, have you ever noticed a change in the sound with different lengths?, I may ask Tara labs concerning this, Happy listening.
I thought that the longer cables have more surface area to disperse/filter noise.
Leicachamp, you talking on the technical side of this; which was brought forward mu query.
As an example we've seen in school how standing waves set up. There are always reflections back into power cables; is length a factor there? Can there be an ideal length for our purposes-taking impedance, capacitance, reactance into consideration? What about distance to "boxes" a la MIT Oracle 2? Knowing so little allows for a lot of questions for as it is said out there, for every action there is an equal and opposite reaction. I hope there's a braniac out there who "reflect" on this post.
@ Leicachamp, Hi, I understand your thoughts here, you make sence with what you said, have you done test?, have you ever heard differences in lengths of 3ft, 5ft, 6ft, with the better power cords in the industry?
