Power cable architecture from start

Hello guys,

So, I am taking the first step to start upgrading the cables in my system (N20--> Tambaqui --> Luxman509z --> 805D4).

I am planning to start with power cables. I have a dedicated 20amp recepticle on a 10awg wire. Currently everything goes through that with a cheap power strip.

This is what I was thinking. Please help me refine, add to this as you see.fit.

1. Get a puritan PSM156 conditioner. Get a HC 20 amp cord for it ?

2. Get C15 cord for Amp HC I guess ?

3. For DAC/Source get 15 amp C15 power cord.. should this be high current or Noise reduction.. for shunyata I see NR/HC varieties.
