Power Conditioner, which of these 4 and why?

Good questions, i left that out

Needs? Not sure, just clean up crappy NJ power grid electric.

system: mini-pc into Chord DAC into PrimaLuna evo-300 integrated into GoldeEar Triton 1R

thanks

Thanks all for input.  I bought the Shunyata listed above.  

To Tuberist: re: PL integrated with the triton 1r.  The amp and speakers not broken in yet, but a match made in heaven.   The mids/highs are way better and more defined than i thought would be.  The bass is ridiculous, hit you in the chest type bass but not too boomy (recording dependent) but you can go, since build in amp, turn the knob to bass level for room. 
supper combos, these 1r’s Blow away speakers i have auditioned at more than double their price.
