I once used some speakers, one a couple feet from the amp and the other was 8 feet away. From bulk cable, I cut a 5 foot length to wire the closest one, and a longer one for the other [to keep excess wire from the floor]. Didn't seem to bother the sound to me, but when my pal [who thinks a lot] said it would bother him to have things set up that way, it started in on my head, too. A few days later, I changed out the shorter one for an equal length one. Didn't seem to make a difference, but mentally I felt much better.
