Which powercord has the best Mid?

I think NBS Statement has the best Mid. I did try BMI ELITE. However, I did not try Fatman. Any recommodation?
I have just finished my testing on a few power cords. It seems that the ones that have good mids are dark sounding to me. I like a cord that is true throughout the audio range. NBS and Pure Note so far are the best IMO.
Myliang you need to be a little more specific. To some people a powercord that is the fastest available is considered the one with the best mids, to others it is the cord with the most body and bloom, to others the one with the most delicacy and finesse, and to others the one that is the most dynamic with the most transparency. What is it that you are seeking in the mids?
