All I can say iswith my OPPO 105 player. Although I am using both Audioquest power cords-NRG100's, 1000, plus two Audioquest Niagara 1000's, that a $400 digital JPS power cord works far, far better with my OPPO player. When I replace my JPS digital power cord with a $1280 Audioquest power cord to my OPPO the audio quaity goes way, way down. In fact I wonder ifeven a 2-4 thousand dollar Audioquest power cord could compete wih my $400 JPS power cord. That is a fact. And I plug my JPS power cord into a Niagara 1000 strip, itself using a NRG1000 power cord. The JPS allows my OPPO 105 to really perform at a much higher level than if I used a much higher priced Audioquest power cord with it. Again, that is played thru an Audioquest Niagara 1000-NRG combinaton. And, again, I only know this to be true with an OPPO 105. It is immediatly apparent when switching power cords-no having to go back and forth to compare. It wil be immediatly apparent to anyone trying this comparison.
