Shunyata Upgrade Assistance Needed
 

My system consists of a Linear Tube Audio amplifier and preamplifier. My source equipment is a PS Audio Directstream DAC and Memory Player. I also have a Esoteric phono stage feeding a Rega turntable. The source components are hooked up to a Triton V1 on a dedicated line. The Linear Tube Audio amplifier and pre amplifier are on separate dedicated lines and not hooked up to the Triton V1. The two Linear Tube Audio devices are powered by Ztron Alpha Analogue power cords. The two PS Audio devices are powered by Ztron Alpha Digital power cords. I have the following questions:

1) Would the newer Delta NR power cords be an upgrade for me over the Ztron Alpha Analogue and Digital
2) Would I be better off to first upgrade the Triton V1 to V3 or upgrade my power cords to either the Delta NR or the Sigma NR and keep the Triton V1

thanks
