I had only an aluminum cable with copper alloy / color (CCA). This means my Jamo S 606 and the Canton Movie CD 102 surround speakers connected to my Pioneer VSX 919. After I read that a pure copper wire to connect the speakers better, I bought me this copper cable for little more money. I was left with the conviction that it sounds better. However, the new copper cable is outside thinner (thinner for PVC Mantle) and more flexible - so to relocate better. The aluminum cables the wire were brittle and when installing always remained stranded pieces in hand or on the ground. My Two sets are: for all have some quality system.
