How important is it to have identical speaker cable length?

Thank you guys very much for the thoughtful advice!

Just make sure they are the same color.... 

My deep seeded neurosis won’t allow me to do that. I would lay in bed staring at the ceiling. But for normal, well adjusted people it’s no issue what so ever. Only issue I can think of would be value when it’s time to sell. All the best.

LOL @ arch2

I would not fret…

But when the capacitance is # pF/meter, and inductance is @ uH.meter then the number of meters can matter.,, and the resistance is also expressed in @/meter (or per foot in freedom units).
It should make a measurable difference, which is better than a physiological difference. IMO.
But I doubt one would hear much of a difference. The room would likely have more of a difference.
