My understanding was that the wall warts plug into the power conditioner and has the same type of impact the the LPS would have?  Thank you for the feedback!

+1 @c_avila1 A LPS and a power conditioner do different things. It is common for a LPS to be plugged into a power conditioner. Acquiring the Niagra 1200 is probably a good thing. But, the wall wart is still the weak link in the chain. It should be replaced with a LPS.

Ok, I understand your point about the wall warts being the weak link.  I spoke with Chords North American Distributor.  I have two key pieces from Chord, the Hugo TT2 DAC and the M Scaler. They were adamant about not replacing their wall wart with a LPS.  I am not sure why... Their response was that the entire power system was designed to be what it is and any change will have a negative impact on performance.  Any advice?

I would listen to Chord. I've  talked to the manufacturer of my dac and they said to use what comes with it not to mess with these aftermarket suppliers of cords it's a waste of time and money.
