In comparisons between short 1m and longer 3m speaker cables of the same brand the shorter cables were superior. I tested this out with several amps/speakers over the years and the results were unequivocal; shorter speaker cables are better. However, in most applications they are not practical. It is advantageous if you can use shorter speaker cables.
I strongly suggest that quality speaker cables for all runs, regardless of length, are necessary to achieve best sound quality. I constantly set up different systems with various cables to subwoofers, and the quality of the LF changes dramatically with cabling used to them. Subwoofers also vary substantially in sound quality due to choice (if offered on the sub) between line level and speaker level inputs. As might be expected, line level input cable quality also impacts performance. YMMV
