OP,
I am really sorry for all those unhelpful posts by @jasonbourne71. That is his thing.
I only own an Audio Quest Hurricane for my amp. After working through many other power cords it just completely hit the right (neutral) tonal balance and low noise floor. I compared with quite a few other PCs.
But I have not tried a Dragoon or Isotec. Given the chatter from folks that have gotten Dragons, this would be my first choice. But at this level, you should be able to try and compare.
