I now own the Niagara 7000, 2-1200's and a 1000.
On my 7000 I am using the Niagara Dragon. Awesome combo. Really brings out the power of the 7000.
On my other units I am using my homemade 12-gauge Solid silver with NCF fittings.
I guess what I am saying is even though the Niagara power conditioner are great in their own right adding a very hi quality power cord does provide benefit.
