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.
