I have heard differences in sound between a 1M and 2M interconnect, so I would not write off the possibility that a significantly different length of speaker cable could sound slightly different.
However, the issue for me would be moot; the design/quality of the cable would trump the effect of shortening the cable. If one has a poor sounding wire shortening it will not save its performance. IMO, one would do better to pay attention to the sonic quality of the cable as paramount vs. the length (within reason).
If comparing cables of two different manufacturers and different lengths I would not assume that a poorer sounding longer cable might be much better if shorter, i.e. 3-4 feet.
There are enough compromised systems and compromised ears out there that this issue will never be resolved. :)
