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.






I agree with you that Puron need time to settle for maximum effect.


Thus I let them  stay in their place.


Some people ask me to upload video to compare the effect with puling them in and out.


But I ignore the requests.😀



I received my Puron and am experiencing outstanding improvements in SQ across the board. I started by playing orchestral music thru my Node2i, after about 15 minutes the massed strings had more detail yet kept their smooth presentation. The soundstage was more spacious than with my High Fidelity plug-ins alone, instruments had more air and space, bass was deep and tympani was tighter and more detailed.


I have 2 dedicated lines, both have HF MC-0.5's in the duplexes. Digital is plugged into an EquiCore 1800 with DeepCore 1800, analogue (preamp and amp) uses a Wiremold strip with one MC-0.5 and the Puron.

This is the most effective tweak I've used since adding the Core Power Equi=Core and quite possibly better than my 5 High Fidelity conditioners.




this would be a good thing to have evaluated by audiosciencereview.

for the “science.”

otherwise it’s like Reiki or homeopathy, unable to withstand RCT scrutiny beyond placebo efficacy.

(BTW, what I’ve learned since med school in the 80’s is, you stick with this business long enough everything you know is wrong.

 I forget, is coffee “good” this year, or “bad”?

@normb I don't even need measurements (of what? If we don't what it does, what shall we measure?) But I do require blind listening tests to see if anyone can tell if it plugged in or not. Even that would be meaningful, if conducted honestly.

And yes, all I was taught at UCL/UCH has been deemed wrong over the years. Made me laugh when I realised there was a time you would fail your fellowship for saying you'd give a β-blocker in CHF, and now you'd fail if you said you wouldn't.
