Power Cable for Genesis 501's servo amplifiers

I recently bought a pair of Genesis 501 speakers. Is there a power cable that you'd recommend for the servo amp that controls and and provides amplification for this speaker's subwoofer system?

I am currently using David Elrod Signature 3's for my amps, but was wondering if there is a particular power cord that works well for (1) a subwoofer system and (2) would not be overkill for this function. I would like to buy a pair to replace the factory cords that I am sure can be bettered.

Are there any power cords made/marketed specifically for subwoofers?

How about a regular Elrod? Or something even less expensive?

they can definitely improve the bass dynamics and definition I just have a good but cheap XLO TYPE 10A currently on my woofer amplifier/crossover.
