What power cord to use with a Theta DreadnaughtII?

I need some suggestions on power cords from any dreadnaught owners. Thanks.
I am getting great results with the Harmonix Studio cords on my Theta Citadels.
Thanks. What type of improvements did you hear from the cord? And did you audition any other power cords besides the Harmonix Studio cord? Thanks again.
The Harmonix cords are very quick and have nice bass slam.
Great construction also.
I have not really done a lot of comparisons.
I Use WireWorld Silver Electra on my Theta gear with great results!
