Do you believe it will make an audible difference in sound?
The short answer: No.
The long answer: I doubt that very many people would assert that a pair of 101 cm interconnects would sound any different than a pair of 100 cm interconnects that are otherwise identical, even though the shorter pair would have 1% less resistance, inductance, and capacitance, and a 1% reduction in the magnitude of various other possible effects such as those which may result from dielectric absorption and skin effect. So I see no reason to expect an audible difference if one cable, rather than both, is made 1 cm shorter or longer.
Also, if there is any concern regarding the arrival time difference at one's ears that would result from the length difference, the amount of time required for the signal to propagate the extra 1 cm in one of the cables will be approximately 0.000000003 seconds for the slowest moving audible frequency (20 Hz), and far less than that for most other frequencies. 0.000000003 seconds corresponds to the amount of time required for sound to propagate through air over a distance of approximately 0.0001 cm, so the resulting arrival time difference would be the same as the difference resulting from one's head being 0.0001 cm closer to one speaker than the other. In other words, completely negligible.
