About CCA you read elsewhere on Amazon:
"Please note
due to the high copper commodity prices often inferior CCA cables are offered as a high-quality speaker cables, which are made partly or entirely of aluminum instead of copper and only besitzten a copper coating. However, aluminum conducts about 50% worse than copper.
When speaker cables audible quality differences between CCA and CU cable come clearly. "
Fair to say that the mentioned quality differences mainly refer here to the volume if you can not just move in high-end range. The lower the conductivity, the greater the volume loss through the cable. One must then turn up the system a bit further. Or you just take a higher cross-section as compared to copper. But then the price differences into perspective again. There remain then but still the poorer mechanical properties. Thus, the capillaries are here significantly thicker and therefore crumble at the ends you up times, especially if they are to be screwed. One can the cable so if at all good conscience use the spring clips, which are so common in beginners equipment. In higher-screw or plug connections you will not be happy, however.
Here, since the client is not adequately informed about what he gets and what impact this has (larger cross-section required), I can only be awarded one star.
