Purist Audio Power Cables

Looking for some thoughts. I have pass labs amp, pre amp and oppo 105 front end. I demo'd many cables and decided and purchased Purist Audio Musaeus Luminist interconnects and Speaker cables. I was then introduced to PAD Power cables.. and I was Blown away. Since... i've now got Praesto Canorus on amp and Venustas on pre and blu ray. All lengths are 1.5M and run each from a seperate circuit from wall. It was mentioned that I should try a PAD LE into their new power extender box then connect my existing cables to units. Any thoughts on whats best.. ie using a box, or would a LE into amp and say Canorus be better?
