Power cord upgrades for Krell amps


I'm looking for ideas and recommendations for upgrading the power cords on my Krell fpb 350M amps. Does it really make that much difference?

In my sistem to power Krell KSA-300s the best power cord
is Purist Dominus/Ferox, that very very best sound .
Purist Dominus/ferox epsom saltsem quadrotriticaly...had it, ok but nothin gonna do what the transparent MM reference do!!
I use Elrod Statements on my old KRell FPB 600. It was an amazing combo, adding smoothness and extenion and removing the last artifact of solid state. Suffice it to say I felt it placed the Krell in a different class that is still competitive with the best today.
