Power Cable ~ $300 - Which to get? Nordost, Audioquest, Furutech, Shunyata, Zavfino?


I just upgraded to an Audioquest NRG-4 for my amp, which already has made a bit of a difference, however, I am getting a new Audioquest Power bar/conditioner, and wanna connect the entire thing to the wall (will be wired nicely later).

I was told to get the best cable I can get from the power strip to the wall... hence looking for a mid-range power cord, say between $300-400 and not too bulky with some flexiblity... what do you guys recommend? Audioquest Monsoon? Nordost Blue Haven? Furutech, Shunyata in that price range... or Zavfino which is the only one making OCC cable in that price range! Even if a bit higher it's ok, as there are always specials here or there.

Any ideas? Suggestions?

@rodman99999  Thanks, I will try both. I am getting the new Audioquest Niagra 1500, which has two high current outputs and apparently those don't impact the sound like others do, but only way is to try.

In terms of some of those magical cables with snake juice and unicorn dust... SORRY, not only I don't believe in any of it (I am an engineer), but also I didn't HEAR any difference. While there IS a noticeable difference in sound between stock OEM throw-away cable and Audiophile power cables with good construction, good conduction and shielding, I haven't heard any difference between those $300 cables and $20,000 cables.... sorry, either my ears haven't had the unicorn dust embedded in em, or they're a scam! To me, better copper, better conduction, better shielding would have an impact, but that's it... it's not rocket science!

@alexb76 - I almost envy your inability to hear the differences, that biasing a cable’s dielectric can make(etc). I’m assuming you considered the vast plethora of variables, that may have made that so. I suppose, I could have saved a lot of money, were that my story. However; my ears were my primary source of income, for about four decades, so- I really have no regrets. Perhaps you missed it: The cable I suggested IS a, "$300 cable". It’s just been favorably compared, to the upper crust. Happy listening!
You don't need to spend more than $50... check this out. It's a 16mm (10 awg) Hi-End Rhodium plated 4N OFC 99.997% pure power cable. I don't think anyone (even Mozart) can tell any difference between this $50 power cable and some stupidly expensive (treated with snake oil) AQ or SR power cable.

It's likely that a Ping cousin will be along shortly telling you about an expensive to buy (but cheap to make) SY industrial cable from his favourite audiophile company.  But moving along, I've found that DH Labs PowerPlus is good value for money.  You can buy it by the metre in some places and then use your own choice of connectors - if you understand how to connect power cables or have an electrician friend.
