We do have a cable thread somewhere on this site that might be better for cable-specific posts. As far as purely electrical "issues", in the end, better sound is still the main consideration. Shielding power lines is not only very difficult to do, in practical terms, but it is not in any case a perfect solution, since any reduction in noise by shielding comes at the cost of reduced quality of "remaining" sound in the end. God only knows why this is so. My own experiments show that crossing (braiding) power cable wires also introduces sonic "issues" even as it serves as an imperfect RFI/EMI "shield", probably by reducing inductance. I presently use braided 12 gauge magnet wires for power cords to my amps, where each of 3 wires is sleeved with soft polyethylene tubing, and the ground wire "floats" only on the component end, serving as a "drain" to ground for parasitic noise. These power cords "work" better in aggregate terms than other expensive cords I have tried, but they don't address surges or other on-line noise issues at all. Sadly, the "high quality" surge guards I've tried have been bad for sound, so I just take my chances. I have to confess that where I live, lightening is rare; but there is a LOT of noise "in the air" and on the power lines, which are, after all, perfect "antennas".
Back to lightening, it takes many forms, another study, in itself.
