I purchased a Paradigm system from my local dealer. Two Mini-Monitors for the front, CC-370 for center, and ADP-170 for the rears. I am going to get bettercables speaker cable for my front and center but for the rears should I just use the 12 gauge that the local dealer threw in for free? Or should i get a higher quality speaker cable for the rears? Will I be able to tell the difference or waste of money?
