Different lengths L/R speaker cables

[GerardJ]

Regarding WW Silver Eclipse 7 speaker cables:
Causes one side with a SC of 3.5 meter and the other of 2.5 meter a lesser sound quality than SC's of equal length?
I now use a pair 3.5 meter Silver Eclipse7 SC on my TAD E1 and would like to buy a used extra pair of 2.5 meter for real bi-wiring!
Comments appreciated.

The sound from the speaker with the shorter cable will arrive at your listening position 0.0000000002 seconds earlier than the sound from the speaker with the longer cable

I suspect it won't make a bit of difference unless the resistance of the cables is significant.

Thanks for your reply!
I asked because as said I would like to get a used (to cut costs) second set of speaker cables for biwiring, but unfortunately 3,5m (12 ft) is not often offered second hand. So that's why I wondered if I could use a more common set of 8ft or 10ft SC on one side and my 12 ft SC on the other side without a negative influence on the sound quality. I know that some engineers say it could not make a difference, in accordance with what you said. Others say that because of the complex effect of impedance, induction, capacity of the cable, you should best use same length for L and R.
But what I am curious of if anyone using a good audio system actually tried it and heard a negative effect on SQ and not only approach this aspect theoretically?
