Shunyata Sigma V2 vs Synergistic Research Atmosphere level 3

Shunyata Sigma V2 VS Synergistic Atmosphere level 3 power cords.

Can anyone provide some comparison information on these 2 power cords? ? Sound Quality 


Obviously I was just poking fun at marketing :)

I did have a Sigma V1 and SR Level 2. I didnt a/b them...but both were excellent cables in my system. Ultimately I went with a Mix of Hijiri Nagomi and Wywire Diamond PC's.

aniwolfe What does the  Hijiri Nagomi do better than the Shunyta and Synergistic?
