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?

A power cord that requires additional power....Irony?

Lets think one step further...better wall wart.  Perhaps the aftermarket  cryo'ed MKII.

NOW you're cookin....
@tablejockey - Actually, Michael Spallone, our resident Synergistic MPC guru/AudiogoN member, does upgrade the Synergistic MPC(wall wart) and it makes an audible improvement(with interconnects anyway). https://forum.audiogon.com/discussions/modding-synergistic-research-mpc-to-galileo-status-2 However, I wouldn’t expect those attending or spinning, at a wedding or Bar Mitzva, to notice the differences(totally different objectives/style in, "cooking").
@alexb76 -   btw:  Generally speaking: connecting one's power amp, directly to the wall outlet, will sound better than through either a power strip or purifier(when combined with a number of other devices).
In addition to the recommendations I made above, I'd give a big +2 to @millercarbon Synergistic recommendation.  You just simply can't go wrong buying an excellent $2k cable for around 300 bucks.  Cables just haven't progressed that much to overcome that price big of a differential IMHO. 
@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!
