I made DIY 20 amp power cords for my Guardian 2,they are about as long as my half metre Shunyata Annaconda Helix on my Hydra 2 for my amps which have standard length Annaconda Helix on the mono blocks.
Originally the DIY was the same length as the amp power cords, but I cut the power cord in half, and then doubled the cord, using one 4 strand set of wires for the L and the other 4 strands for the return.
This improved the bottom end so much, I dobled up on another pair and made another doubled up power cord for my cd player.
Definetly upgrade the receptacles, even if you never change the wire.
I have had good results with the inexpensive copper connectors from Furutech.
Someday I may make the move up to Oyaide.
