Unfortunately, I knew before buying not know what "CCA" is, otherwise I would have equal refrained. Since then, I know what it stands for - namely cheapest Alustrippe that probably once located sufficiently close to one copper has to look like copper cables - I feel the advertising message "100% CCA" just "misleading". Fitter, tougher terms (So roughly in the direction of "Ver-back-ung") allows most Amazon not # -)
Immediately sound the copper-clad aluminum is indeed probably not have a negative impact, because "sound" cables known yes not, except that they were defective. But some concerns about the purely electrical properties such as brittleness and contact resistance I'm at Alu vs. "Real" copper already.
