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.

I’m a big fan of Empirical Design power cables—the ED-416 would fall within your budget. I’ve been using Karl’s cables for over a decade. So many component changes over that time—same power cables. The ED IC’s are also great, reasonably priced cables—still using them after many years as well. FWIW, these are the only cables I’m aware of that won the TAS award two years in a row.
I have a Monsoon on my PrimaLuna integrated. I could easily hear a difference I liked, more tone, body and detail. You must do a home demo to decide for yourself
