Best Power cable around/prefer under $300....


I’m looking for the best Power Cable for a Parasound A21 amp.
I would like to stay below $300 because I feel any aftermarket cable would be a huge upgrade compared to stock.I would really like to hear what you all think! 
I am considering the following,

Shunyata Research Venom HC V2 Power Cable. $298
AUDIOQUEST - NRG-4 15A IEC Power Cable. $180
AUDIOQUEST - Monsoon Power Cable $329 
NORDOST - Blue Heaven Power Cable $219
NORDOST - Red Dawn LS Power Cord $384
AUDIENCE FORTE F3 POWERCHORD - POWER CORD $143.

One of our audio club members tested several power cables and he recommended the Shunyata Research Venom HC V2 Power Cables. I have them for my Marantz PM-KI and SA-KI RUBY integrated amplifier an SACD Dac. I found a special package deal of a 3 cable bundle.
Might consider Audio Art Cables pcs, a couple models within your price range; and looks like there presently is a sale. I’ve been pleased with them in my systems.
