Puritan PMS 156 vs. Audioquest Niagara 3000


Has anyone compared these to conditioners to each other?  I would be using them for my front end and 150 watt solid state mono block amps.  I can kind of get a feel via some of the reviews but was looking for a direct comparison on the sound signature.  Hoping to achieve a lower noise floor without restricting the dynamics or existing tone signature.  Thanks.

I’ve always wondered what a system consisting of only ASR approved components would sound like. 

@phillyb it depends. If the people listening were ASR acolytes and they were told everything measured perfectly and had been blessed by Amir, there would be no system ever that could compare. If it was done blind, likely, "fine".
YMMV

ASR are the most uneducated bunch myself and most veteran Audiophiles distain 

in dacs comparing a $800 topping to $5k well know dacs for better specs  the 👂 ear is what counts most the Puritan I have writte to them many times ,Furutech makes a gold copper ring the outlets sit in ,and the brightness is because Puritan is too cheap to use quality outlets Gold over Copper is a quality outlet .

Puritan uses cheap Hubble type outlets made of Brass which is bright vs Copper 

Copper is 3x better conductor,3x less resistance,noise, they refuse to listen. My friend bought the zpFurutech Rings as you can see on you tube , and he  installed 

gold Copper outlets night and day better for about $600 in parts .

AQ 300 for example All outlets are gold Beryllium Copper . If buying the AQ
