At least arch2 is keeping it real. I would also be more inclined to have same length of cables for L/R speakers purely due to OCD. I would speculate though that coiling one cable vs other being straight has more chance of resulting in actual audible difference.
How important is it to have identical speaker cable length?
I have a situation where my speakers are different distances from my amp. Would it be wrong to pair a 3-meter cable to one speaker and a 2-meter cable to the other or is it really just a theoretical issue? Many thanks in advance for your thoughts!
