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?

After a lot of research I am leaning towards the Audio Art Power 1 PC. they have good specs and come with Furutech ends. They are in the $165 range on an introductory price offer.., Thoughts or comments?
Puerto, it's always a wonderful idea to expect a miracle from a new value driven product...I know I have! At the end of the day, when you have the money, a Transparent MM reference, an MIT Oracle AC 2 or a Kimber PK 10 power cord will transform any system for the better. All other dablings will offer marginal improvements at best....the cable company will let you experience any of the above, if you dare!!
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!!
