With the best stuff, and being able the hear the difference between cables, the length of a cable could have an effect on the sound, as diferent cables do alter the sound, so, perhaps, different lengths of the same cable can have a different effect on the sound tone.
This may or may not be true for you, and the cable you are choosing, but since reselling diferent length cables is very hard.. I would go with the same length too.
Remember, you also may decide to change stuff around, and too short is a killer... where too long is only a small annoyance.
Folks are always selling 1/2 meter cables.. and 1 meter cables.. seldom 1.5 meters or 2 meters... as those are usually always long enough. The 1/2 meter, which at the moment seems enough... always winds up too short sooner or later...
