What are you trying to fix/improve? Do you think the cable is not well shielded and letting in EMI? If you are having ground loop issues, you can get a power conditioner or something. A power cable carries no sound, if just supplies wattage, a $200 cable doesn’t supply more wattage; but as I said, it may be better shielded, but even adding a ferrite bead can help.

There is no difference in frequency response, THD, jitter, dynamic range, crosstalk, etc. Like I said, a power cable just allows your wall outlet to feed into the receiver, so all it needs to do is to be able to support the amount of wattage it’s handling, as well as be decently shielded for EMI.
