Low noise, neutral, high current power cord for wall to power distributor


Hello,
I am in the market for a power cord. It will be connected between the wall socket and my AC distributor. I have come across many discussion which say that this is the most critical power cord and the best should go here. At the moment I use a $200 entry level power cord and it is somewhat noisy/grainy. I would like to get a power cord in the range of $1200 (new or used) that would considerably lower the noise floor and sound neutral/effortless.
I am not in a state to experiment with new kids on the block so I would like to stick to the proven ones:

1. Shunyata Alpha HC (other models are welcome too)
2. Furutech Reference
3. Audio Magic Illusion liquid air,
4. Transparent PLMM2
5. Gigawatt LC-2

Kindly suggest.

The thing is, an Audio Note isis power cord costs just about $500. It was rather laughable how acceptable and in someways it actually sounded compared to a $12k Ansuz Diamond power cord and clearly beat the $5k Ansuz ceramic power cord. It is a very natural sounding PC. It uses pure copper wires and audio note silver plated AC connectors. It goes to show that for a power cord to sound clean and quiet, it is not a rocket science as some cable makers tout it to be
Maybe not. On the other hand, I heard that newest Purist top of the line 30th Anniv. power cord with built-in some kind of conditioner is spectacular. That opinion came from those who heard just about everything and had all previous best Purist cords before. 
Anyway, great power cord for $500 is an audiophile gift.
I do not suggest in any way the the AN isis is the best cord out there. It is just very suitable to this thread title "Low noise, neutral, high current power cord". It costs only $500 is something that grabs attention. Secondly it works equally well in all applications (source, preamp, amp and wall to distributor) without showing limitations in current delivery or changing the PRAT of the chain.

I connected the Ansuz diamond power cord back in the system and it definitely has a more see-through character but it "has" a character and that is transparent, spacious and a bit lean in the harmonics. The isis doesnt have a character that stands out.
