Respectfully disagree, particularly when comparing low grade grainy copper to higher grade purity OFC or smooth OCC copper within interconnects and speaker cables. On a revealing audio system it exposes the difference in an interesting and unexpected way, fwiw.
Sitting here are the exact same interconnect cable designs in OFC and OCC grades, and swapping them on any input source or between preamp to amplifier, the difference is audible and notable with moderate hearing capability. As to what someone prefers, YMMV.
