Since some cords use specific geometries to achieve desired impedance characteristics, it is possible that altering length could alter their overall performance. With that in mind, doubling the length of a cord could double the effective capacitance. In a reverse situation, using a cord that was half as long would cut the capacitance by 50%. Same can be said for inductance too. Whether or not this would come into play at all would vary from system to system and location to location.
Another factor that could come into play is susceptability to RFI. A longer cord makes for a better antenna. As such, if you're going to run long cords, make sure that they have adequate shielding or take advantage of geometries that offer "natural" shielding to RFI.
Also make sure that you're using a cable that is heavy enough for the device that it is connected to. Whereas an 18 gauge cord might be fine for a CD player, tuner, etc... it is not suitable for any reasonably sized power amplifier. Sean
