Silver-plated copper is typically used with Teflon insulation, while all-copper can be found with some sort of PVC or combination rubber-PVC insulation.Teflon insulation is the best for detail, but makes for a stiffer wire. Acoustic vibration in the power cord gets in to the equipment and may muddy the bass. Applying an acoustic damper that does not have bad dielectric properties would tame this problem. Alan Maher recommends the EAR C-1002 damping material sold by Michael Percy (although it is vinyl). I have not experimented with this, but I do know that vibration is an issue in all audio cables, and that the insulation found in UL-listed power cords does dull the sound.
