I will say this as someone who only uses a single puron
It does make music sound more real. You would have to hear it for yourself. I have very expensive electronics. Im very fond of my stealth audio and nordost cabling though-out and i love my synergystic power conditioner but none of them ever made certain songs sound so realistic.
It could be the culmination of everything though. I cant just say it was the puron thats not fair to my other components
my only complaint, which is a rather large one, is that some songs sound too aggressive/ bright with the puron vs when i take it out that tension seems to go away. But like i said its not for all tracks and my wife hasnt noticed (but im very sensitive to it)
the cool thing about the puron, its VERY noticeable in effect. Something unbelievable for only $250
this is not something where you have to say.. hmm well i think its doing something? You dont have to a/b it, the effect isnt subtle
thats why i like it but its not a true power conditioner in the sense it will do anything to actually filter your ac…. Which is a good thing because like i said earlier thats a very expensive endevour and most products that try to do so struggle and this includes both the p20 and also the entire line from stromtank which can be in the tens of thousands of dollars for some models
from what I understand this actually tries to override noise with more pleasant noise (some noise sounds good to the human ears) which is possibly why the guy with 8 of these is getting high noise readings
finally to touch back on the brightness topic. Im not being completely fair to rhe puron. Its just one piece of a larger system. Im due for a dac upgrade. I think the mola mola tambaqui will help smooth out the sound and give me what i want.
Also i have been using a generic ethernet cable for streaming. Im sure when my new cable comes things will improve even more
