Smaller plug-in AC Purifiers -- Shunyata, iFi, Puron...something else? What do you like?

@hilde45 ,

 I did not initially believe in that big thread the users were raving about Puron. But finally decided to try because there was money back guarantee. Not going to say much on the improvements because I am not only keeping the Puron, but I have ordered a second one.

You really have nothing to lose. Just return it, if you don’t like it. I doubt you will return it.

I bought a Puron a few months ago. Plugged it in to the same circuit behind my system. I think it's snake oil if you ask me.

@judsauce 

Were you able to return it? Unfortunate that it did not work in your system. Certainly worked in my system and I am loving the results.

If you ever call Denon support they always ask you if you're using a power conditioner and tell you that they don't recommend them. I still use one I'm not frying my system in the event of a storm and I do notice a difference also on my OLED 

I don’t go for the small passive power conditioners because it seems nary a one explains how it produces audible reduction of noise, which may not even be audible in the first place if it’s not measured on the premises ad hoc. For me, the lack of functional info (or patents? Do some of these have associated patents I didn’t see?) is a problem barring commitment of my time and money.

I do use Clef Audio Power Bridge 10’s. They allegedly filter this and that, but they definitely serve as surge protectors, and the latter’s what I wanted.

The Clef’s are also decent for catching bona fides in the “you gotta have a power conditioner” community 🧐
