I'm not sure how someone could say with a straight face that a cable X 5 or more longer wont have an audible difference between its much shorter counterpart.
There is no getting around the fact that all electrical parameters involved with the wire in question increase as the distance increases. More Capacitance, Resistance, Dielectric and Shielding influences on the sound and lets not forget the increased chances of the wire acting like an antenna.
Then there is the increased cost of having more wire then is really needed but that is a whole other topic but not an insignificant concern depending on the wire in use with todays sky high prices or esoteric wire @ $1k per/ft or more.
When I was able to use very short (2ft) and rather inexpensive (Mogami) speaker wire in my system I could hear low level details on certain songs that several well known and esoteric brands of wire @ 20X the cost and 8-13ft long could no longer seem to uncover playing the same song on the same equipment.
