Sonic Diff between a 6' 1.8M & 4' 1.25M PC


Is there a difference in sound moving from a 6' power cable to a 4' power cable? I read somewhere that you only hear that last 6' of cable but would like to understand the concept so I can make a more informed decision. Its a hot mess behind my equipment rack and I would like to clean it up but not at the sake a sonic performance.

If you can use the shorter power cable then do it and see if it really matters to you, not some self proclaimed expert. I have seen shorter ones than that and I can't tell you they had any negative impact on the sound, but maybe I am not as expert at critical listening as are others.
