Amp ac cable connection

I find with the recent addition of 2 Audioquest Niagara 1000's for my audio system with excellent results.  I am using Audioquest power cords as well.  In fact I am using my second one for a pair of Martin/Logan SL-3 electrostatic speakers.  Using An Audioquest NRG 100 from the wall to the conditioner and a pair of NRG 10's from the Niagara 1000 to the speakers.  Previously I was using an inferior power conditioner and ordinary power cords to the speakers.  The changes were simply incredible.  Anyone with a speaker such as my Martin/Logan's, which themself need to be plugged into current to power the subwoofer portion of their speaker will need a combination such as I have to achieve the full potential of their speaker system.  But, again the addition of some of the very latest power conditioners, such as the latest offerings from Audioquest really work.  On most audio products, as well-unlike many of todays competing products that will work for some products but not for others.  Anyway the Niagara only runs $1000, plus it has spike protection s well.  That is all I can say on the matter, except they really work.
