Do speaker cables really make a difference ?

In my humble opinion if the cables have sufficient insulation and are the correct Guage for the power you have and high conductive core. anything more is a waste of money!!

I keep seeing comments about the different sound you get from different cables. I don't want cables with a "sound signature" I just want my cables to send through what is there not change it. This takes us back to simply proper gauge for length and amount of power you have.
