Nice to see a thread about solid core conductor power cords - I find they make a worthwhile difference compared to stranded conductors, insofar I'm able to tell with the testing and comparisons I've done. Mine are DIY 12/15AWG installation wires bought at the local "Home Depot"-style warehouse (Bauhaus). I stripped the individual (and insulated) solid core wires from the outer sleeves, and then twisted the lead and return wires with some 3 twists per 4" (ground wire, where it may be used, is twisted in the opposite direction), and terminated each end with IeGO 8055 pure copper connectors. The twisting itself should act as a mild electrical shield, and I use no further insulation or shielding. The installation wires are quite cheap (usually sold with 3 or 5 conductors under two outer sleeves), but use high quality, very pure copper - at least here in Denmark, but I suspect the same applies in other countries. I wanted to avoid alloys in the connectors, and therefore opted for the IeGO pure copper plugs both for the wall outlet and components. The sound through my setup with these power cords seems dynamically uninhibited, pure and with very little inherent signature. Try them out cheaply without dedicated connectors to begin with, and see whether they're to your liking.
