Prioritization of Power Cords

Hi All,

I'm trying to figure out where to prioritize my power cords. Here is my setup: 

• Audioquest Niagara 1000 Conditioner (currently connected to the wall with a Pangea AC9SE Mk II 7 gauge PC)
• Line Magnetic 805ia Integrated Tube Amp (currently connected to the Niagara with an Acoustic Zen Tsunami III 11 gauge PC)
• PS Audio Directstream Junior (currently connected to the Niagara with a SignalCable MagicPower Digital Reference 12 gauge PC)

If I were to get a Audioquest Thunder or an Acoustic Zen Gargantua II PC, where would you put this cord in this setup?

Thanks!
