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

I'm very happy with the improvements the Puron has delivered to my system.

@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
