Shunyata Delta NR or ???

Recently moved my Shunyata Venom HC power cord from the external amplifier to the Shunyata PS8 I purchased. 
Being satisfied (for the time being 😉) with both the Voodoo and Shunyata products I'm running in my system I'm considering purchasing a Shunyata Delta NR for the external amplifier. Thinking Shunyata over Voodoo simply because I'm unaware of anything Voodoo offers with noise reduction. 
Question I have is, based on experience, can anyone make any other power cord suggestions in the $600/$700 price range that offer noise reduction I should consider?
System is Oppo 203. Marantz 7012 with Voodoo Vision Digital power cord. Monoprice Monolith amplifier. Shunyata PS8 with Shunyata Venom HC power cord. Tekton Impact front channels, PSB T55 rears. Morrow Audio SP6 cables to speakers and Morrow Audio MA2 interconnects. SVS subwoofer. 
Any help is appreciated. 
For around your price, you could likely pick up a used Shunyata Alpha HC power cable (one on sale here now for $750 (I'm not the seller)). 

Excellent for amps/power distributors and includes noise reduction. I have 3 of the Alpha HCs in my systems (one each for two subwoofers and one powering a SS amp). All but one PC in my systems are Shunyata.

I've also seen a used  Alpha NR (current generation) power cord for sale on Audiogon (the Alpha is next up in line from the Delta) for about $800; normally retails for $1500 I think.

I think that any of the Shunyata cables would be good, but I'm guessing that the hierarchy in quality is Alpha NR > Delta NR > Alpha HC.
