With Kimber Kable, the answer is no!  There will be no audible difference in sound provided the shorter cable is greater than half the length of the longer one.  Its a great way to save money and keep your room tidy.
Here is an example:   Right Channel = 3.6m  Left Channel 2.2m  is OK,   but 1.0m + 4.0m is not recommended (here we would suggest increasing the 1.0m to 2.0m).
