Zu Definition II bass amp power cords

I was given the opportunity to demo a pair of Transparent power cables on the sub amp for the Zu Definitons and found an upgraded cord made a very positive impact. I am wondering if anyone has used aftermarket power cords on the sub amps that they recommend?
Jena Labs Model One.

Change out the jumpers on the Def2 to JPS Aluminata and hear the difference. Bigger than the AC cable on the bass.
