The best plug in filter ever!

Puron AC Power Conditioner by Greg Voth


After reading rave review of Puron AC plug in filter, I had got one 10 days ago.

For your information my system is very complicated with bi amping and three Farad linear supplies.

Thus I have 14 power cables, one main power conditioners, three isolation transformers.

I had tried plug in fliters from quiet lines, quartet stecker, IFI, furutech, Nordost Qv2 and QX2 fliters.

I still have all of them in my system without selling any of them.

I am collector. 😁

All of them had brought slight improvement but not drastic change.

But as soon as I inserted Puron Ac filter, it made background black with more details and clear bass.

The stereotimes review is spot on.

Encouraged by the result, I had ordered two more of them so that I can insert more of them close to amps and Dac.

Now my system got transformed with more vivid and clear sound stage but not overetched.


This is the best 750$ that I had spent during last 5 years in my audio system.

So here is something that I have discovered with the Puron.

I have just begun experimenting with them plugged into my AudioQuest Niagara 7000 power conditioner instead of at the wall and I have noticed a strange phenonium.

I started by using 3 Puron’s plugged into each of the 3 sections of power outlets on the Niagara. That is: High power, Analog and Digital.

To my surprise, the music is louder, quite a bit actually. I’m not sure if sonically it is an improvement at this early point, but the music is definitely louder.

Can the Puron’s be affecting the circuitry inside the Niagara? I wish someone else with this power conditioner could chime in, or perhaps anyone who can help explain it.

@ozzy I have come across the exact same phenomena using these parallel plug in tweaks over the years, some of them can make the system louder, such that to do a fair A-B test you would have to volume level match.

I can only guess at an explanation, but perhaps certain filters help improve PFC, which allows the amplification stages more dynamic headroom = louder.

Re Louder

I speculate that the reduction in noise utilizing Puron creates a blacker presentation – and thus, louder.

I have had this experience at home

I don't yet have these, but my experience with kit that removes noise is I can turn the volume up without hurting my ears, where the prior noise did

Thanks for the help on this.

At this point however, I think the increase in volume is not a good thing, Sort of like I hinted originally in my first review, it sounds like the volume knob is turned up to 11. Seems to provide more distortion than pleasure.

I believe it has to do with the AudioQuest equipment. That is, I have the Dragon power cords and the Niagara 7000 power conditioners, their claim to fame is their bias conditioning. Whatever that is. I think the Puron’s are affecting that. I doubt if other types of power conditioners would be affected like these are.

More to come...

BTW, 2 are definitely better than one. I can tell the difference clearly on video. One Puron is good but the 2nd one really makes the image pop.
