Power Conditioner: Isotek, Audioquest or other?

Hello Coto37.  I have a Powerquest 2 that I use for TV, router, etc.  I bought it mainly for the quality of its surge protection but it adds value by having a dedicated connection for TV which provides excellent filtering for 4K picture quality.  I have a Niagara 1200 for my hi-fi system.  The noise floor is amazingly quiet and added a superior sound quality.  As others have described it, music against a black background.  The Niagara 1200 achieves its maximum performance when using Audioquest AC power cables.  It's an engineered system concept, and it definitely works.  I also use the Audioquest NRG Edison Duplex all outlet.  If you are going to bring AC to your power conditioner than you should begin with proper connection.  Those $2.99 wall outlets that all houses have are worthless for delivering high current draws.  That said, be aware, when purchasing the Niagara 1200 it comes without a power cable.  They do this so you can buy a power cable that fits your need in length as well as budget.  I use their model, Monsoon, for connecting the 1200 to the wall outlet (the NRG Edison Duplex).  I use Monsoon for my phono stage and theater processor, and I use Tornado High Current and Tornado Source for my power amp and preamp.  The 1200 also provides 2 dedicated high-current plug connections for power amps.  I connect my main power amp and my powered subwoofer to those outlets.  Again, the noise floor is zero and the music to black background is superb.  I can't recommend it enough.  Hope this helps you in your decision making process.
