Power cord for digital stuffs?

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.  

Here is an interesting quote from the Schiit Yggdrasil Manual, take it for what its worth:

Power Cord.

Plug the end of thes upplied IEC cord in here. You can also use fancy audiophile types, but they won’t really do anything—what about the thousands of feet of crap copper cables in your walls, huh?

Whoa, no one ever thought of that before.. 😜

No less true.
