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. šŸ˜

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.

Where do you place the Puron(s) in your system? Have you tried different areas? With HF MC's, plugged into a large power conditioner is least effective.

1 in Puritan 156 and 1 in HFC MC-6 Signature 3D

The one in Puritan156 has greater result since my Jeff Rowland amp and Lumin streamer connect into. Along with my series of MC-05s and MC-1s magnets

other on MC-6 is just a group of internet router, subwoofers etc

You didn't do the blinded trial I suggested to you? Where someone else plugs it in, or unplugs it? You do understand, don't you, that doing it yourself means very little given all the biases that are not accounted for?

Yes, unlike Thomas, I like science. It only means being as certain as you can be about something before you believe it, and especially before you assert it to others. There is absolutely nothing wrong with that, and we have all seen expensive tweaks that we can laugh at. How shall we tell the difference without proper experimentation?

You didnā€™t do the blinded trial I suggested to you? Where someone else plugs it in, or unplugs it? You do understand, donā€™t you, that doing it yourself means very little given all the biases ...

Perhaps it means "very little" to you, but others place more value on such experiences.

No one here is obligated to conduct blind testing to suit your preferences.

Indeed not. I don't intend to force 'my preferences' on anyone. I simply point out that if you don't control all the variables you can, you aren't sure of your own findings. I am as vulnerable to those confounders as anyone. I don't want to spend a great deal of money and then have no way of knowing whether I made an improvement or not. Better still, find out before buying rather than afterwards. If I cannot isolate the thing I bought from every other factor, I'm very likely to let the price I paid influence what I think about it. Don't believe me, believe Feynman ā€œThe first principle is that you must not fool yourselfā€”and you are the easiest person to fool.ā€ It is sad, but true, and also unsurprising.

So let's have no condescending sarcasm. I don't mind what other people believe, nor what they like to buy and believe sounds good. Their money, their business. The issue comes along when they say to others that they should buy it too. Then we need just even a little teeny bit of evidence. No?

@nasamanĀ 

Re: HF MC-0.5's. I experimented with placement, eventually following Rick Schultz's recommendation to start at the wall. I have two dedicated lines, there are 2 MC-0.5s in each duplex and one more in a power strip with amp and preamp. There is so much sonic improvement. Plugging a MC-0.5 in my EquiCore + DeepCore yielded very little effect. Possibly because the HF's need to condition the mains.

Whatever technology the Puron uses, it seems like it will work anywhere in a system. I'm expecting a demo unit from Mark since the Purons are sold out. Maybe you bought the last one.

Ā 

Ā 

@lowrider57 sorry Buddy. I was going to wait til next year to purchase a 2nd one. I want to make sure if the first Puron will work in my system first and if itā€™s worth the money.

As I mentioned earlier about its sounding character, Purons and HFC magnets results in my system a bit differently. I thinkThe Purons sound similar to HFC Q-45T enhancer- warmer and fuller, more musical and authority. (NPS-1260ā€™s crisp, clean more revealing and detailed )

The spot I chose to put on the 2nd Puron at HFC MC-6 power conditioner is just a temporary. I will find a spot for it on my main Puritan-156 Pwr conditioner along with the first Puron and my chain of series HFC magnets after Christmas. Cheers

Note: I have 2 separate dedicated AC lines for each power conditioners via hospital grade Hubble AC outlets.

@nasamanĀ 

My comment about you buying the last one was tongue-in-cheek since you advised me they would sell out and then you made another purchase. Very decent of Mark to send me a demo unit to try.

So, most of your system runs off the Puritan. I split my MC-0.5's between the analogue line and the digital. My Core Power conditioners handle all the digital so I'll try the Puron on the amp & preamp line. Very good description of the sonic effects of the Puron, thank you, it filled in the blanks.

Ā 

Ā 

I have 3 components plug in my Puritan156, Jeff Amp, Lumin streamer and Uptone EtherRegen internet. The rest are for Pwr strip of magnets and now Puron. Please share your findings. ThanksĀ 

@nasaman

Ā 

It is good to hearĀ  your updated impression.

Ā 

I also enjoy music with three Furon filters in it.

As I plan to upgrade Line Magnetic 508 SET to LM monoblocks, I will try more tweaking after the amp upgrade

My own experiences re Puron

My friend from Thailand, Wuti L introduced me to Sudkee, a dear friend of his. A few weeks later I had my first Puron sample.

I have used Puron in the same Duplex that has the Mains for my Core Power 1000. Iā€™ve also used two Purons ā€“ in that same Duplex, as well as Position One on the CPT 1K.

Puron is NOT a Magnetically Derived Device. Puron deals mainly with ā€œtimingā€ which results in a vastly improved noise floor. Many of you have noticed this. I know I have

The results in my two systems are basically an improved retrieval of information. Both the Leading Edge and Decay are improved. I use the same 10 or so tracks when developing the LSA gear, new Core Power or (now), Next Gen Emerald Physics.

A Track that comes to mind is the nicely bouncy beat from Manu Katche ā€“ Keep on Trippin. I also like Ensemble Cello pieces (too many to name) as the Attack and Decay are easy to recognize and articulate in my systems.

Puron is a very good product. There is no web site as yet, but there will be one next week. Puron is an improvement in most systems ā€“ but perhaps, not all. I was going to put Puron in our web site that has our Vanguard Loudspeakers (www.xsa-labs.com) but I decided instead to have a site dedicated to Puron and another Ā new product from Swiss Digital called Fuse Box ā€“ coming soon. For now, those that want to send a note ā€“ verafiaudio@gmail.com

Just closing by saying thanks to those that have supported me and the products Iā€™m involved in. Those not interested ā€“ I understand.

Happy Holidays

Mark

@dogberryĀ Ā  Ā  You are right.Ā  Ā All the others are wrong.Ā  But they are not harming you, they only harm themselves and make tweak salesmen rich.

@corepowertechĀ Ā  Please say how this mains filter 'deals with timing'.Ā  Please say how it achieves 'an improved retrieval of information'.Ā  Ā Sounds like it's you that's selling it, so you must know.

@clearthinker

Appreciate your question.

Puron is not my product and while I have had a good explanation from the inventor and owner of the company ā€“ Sudkee, he made me promise that I would not post about the tech.

Ā 

I realize that this does nothing to satisfy your question, but I also understand why Sudkee does not want me revealing bits of the tech.

With Core Power I can explain why DC Snubbing makes almost any system work and sound better. DC is a BIG issue on the AC Mains everywhere in the world. Puron seems to work best by improving the Noise Floor with its tech

I had a very nice guy call me the other day from Las Vegas. Troy B had an issue with his subwoofers in a very good/high-end system. Puron was plugged in and Noise was vanished. Maybe Troy will post. Very nice guy BTW.

With all ā€œtweaksā€ as called out here and in other places, one must try them in their own systems. Nothing else matters, nothing else is important. Your system is where itā€™s at.

Puron is sold out right now, but I started a list on Friday for those interested. Puron does come with a 30-day Money Back/ No Questions Asked Guarantee. Ā You are charged only when we ship it. Expecting more shortly.

I have yet to have a return ā€“ although Ozzy was not thrilled with Puron is his system, but now heā€™s working with Puron on his video rig. Weā€™ll see.

I am the guy selling them as well as the new Swiss Digital Fuse Box which is ready to start shipping next week. This is also some pretty cool tech and in this case I can talk about the tech and how this nicely made product replaces your ā€œfuseā€ with a copper slug and a micro-processor controlled protection system. Iā€™m sure this product will be something special. Just pure science with some nice back-up information to share.

Empirical evidence is evidence.

Empirical, adj.

1. Relying on or derived from observation or experiment.

2. Verifiable or provable by means of observation or experiment.

3. Guided by practical experience and not theory, especially in medicine.

The first two are respectable uses and comply with scientific method. The third, rather sadly, lets us down more often than not. Much of what I was taught as a medical student in the 1970's was empirical, and now known to be wrong. Very quickly, one learns to put faith in double-blind, controlled, crossover trials rather than the word of an authority. I expect you used 'empirical' in sense #3, and while semantically I can agree that "Empirical evidence is evidence" I have to add it is poor quality evidence and one should not trust it.

Again, I will say I do not mind how other spend their money. It is when they tell us we should do the same that it is right to ask "Why?" and examine the responses carefully.

@corepowertechĀ 

I have had a good explanation from the inventor and owner of the company ā€“ Sudkee, he made me promise that I would not post about the tech.

Ah, the secret technology. Well, of course, now we shall all believe. šŸ˜‰

You might be surprised, but my beef is not against you, as I said, I believe redemption possible. My reason for wasting my time here is that the thread attempts to get us to spend our dwindling resources on a product that has no theoretical underpinning, and which electrical engineers feel is unlikely to work. I'm not convinced by it being secret tech. If it works, patent it, then show us why and how it works. I'll happily eat my words if you show me solid evidence beyond testimonials.

Oh, and Happy Christmas to you too!

@dogberry

Appreciate your reply.

Ā 

My advice to those that are interested is simply this ā€“ buy and try. Decide for yourself.

Ā 

As Greg Voth from Stereotimes and others have mentioned ā€“ this is an easy A/B (blind or sighted).Ā  Plug in ā€“ LISTEN and then Un-Plug and Listen. Donā€™t listen to me or anyone else ā€“ Listen to YOUR System.

Ā 

I remember when I was struggling so much with Deep Core 1800. When it was finally finished we published several AP and Digitasl Scope Captures Ā of Ā Mains itself ā€“ AND THEN ā€“ Mains with Deep Core Ā --- 4 volts on the line went down to 30mV. Proof is STILL in the listening and there are 100ā€™s of Deep Coreā€™s out there. Popular product.


I will ask Sudkee again, but Iā€™m pretty sure he wonā€™t want to provide a Road Map for others. Patent it you say ā€“ that takes some time ā€“ even under Pending.


Listen and enjoy.

@dogberryĀ :

Nothing wrong with asking ā€œwhyā€. Then itā€™s up to you whether the response was satisfactory TO YOU or not. Good enough of a rationale to take the next step: try. If not, just move on. I really donā€™t understand your protestations. We are all adults, and can figure out what my work or not for us to spend the money. I totally donā€™t mind reading other peopleā€™s experiences, just curious by nature, although I probably only take action on a very small percentage of what I read around the web

I did not have much problem with hiss and noise.



But Puron still improve the sound by making bass tighter and overall soundstage more clear.

Hello

I confirmed with Sudkee today that 25 more Puron will be on the way in 7 to 10 days.

I have 9 already spoken for -

If interested ā€“ send your name to me at the e-mail below

I hope to have a Dealer Account opened by tomorrow.

All Puron sales are covered by a 30 day No Questions Asked Guarantee.

Ā 

Send your name to get on the list.

My 15K system is more "musical and less analytical" with the Puron. Definitely worth more than the $250 cost. Buy one and try it.

@mbmi

Thanks very much for your comment. I have sent this to Sudkee

Trying it in oneā€™s system is the way to go. We do offer a 30 day No Questions Asked Guarantee

So, just want to be clear on the application. My set up is

Dedicated 20amp > Richard Gray 400Pro > Power amp

Traditional 15amp > Furman Elite PF15i > SourcesĀ 

So I would need two of these, one for each wall outlet?

So this isnā€™t a ā€œpass-throughā€ unit, but goes into another wall socket?

ā€œI have used Puron in the same Duplex that has the Mains for my Core Power 1000. Iā€™ve also used two Purons ā€“ in that same Duplex, as well as Position One on the CPT 1K.ā€

Ā Iā€™m obviously missing something here, inferring from previous comments.

thanks.

@normb

One Puron will work very well in most systems.

My advice is to plug it in ā€“ in the same duplex where your plug strip resides of Power Conditioner

In my case I used two ā€“ NOT necessary as one will make a great difference and two can also add further positive results.

Thanks

Ā 

Mark

I'm guessing when plugged into the duplex with the power conditioner, the Puron can treat the mains as well as the Core Power unit.

I have noticed when the Puron is first plugged into my video, it takes approx. 15-30 minutes before the image really starts to pop and progresses further with more time.

So, based on this with our audio, perhaps plugging and unplugging to test the results is not a good way to evaluate it. (Even though the Stereo Times reviewer did). There may be a residual effect when unplugged.

Just plug it in and leave it in for a day, then unplug it, wait about an hour, and then listen, do you miss it?Ā 

ozzy

@ozzy

Ā 

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

Ā 

Thus I let themĀ  stay in their place.

Ā 

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

Ā 

But I ignore the requests.šŸ˜€

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.

Ā 

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.

Ā 

Ā 

@dogberry

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

for the ā€œscience.ā€

otherwise itā€™s like Reiki or homeopathy, unable to withstand RCT scrutiny beyond placebo efficacy.

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

Ā I forget, is coffee ā€œgoodā€ this year, or ā€œbadā€?

@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 Ī²-blocker in CHF, and now you'd fail if you said you wouldn't.

@normb thanks for the link. Good candidate. Also at $250 but without 30-day home trial.

Anywho, Puron still rocking the houseā€¦ beautifully.

@normbĀ 

Ā 

I still keep Furutech NCF but its effect falls way short of Puron.

Ā 

Thomas

@shkong78Ā 

thanks. Iā€™m considering this (Puron) for my birthday next month.

Ā 

Ā 

Or not.

i think Iā€™ll wait for some legitimate data, not anecdotes.

Ā 

@normbĀ 

I believe it comes with a 30 day money back- no questions asked, which, IMHO, is much better than any review

Can you use the Puron in conjunction with the add-power eau2?

Ā 

Has anyone did a direct comparison?

thankful,

Perhaps not an exact answer to your question, but I am using the Purons with a Add- Powr Symphony I/O AC harmonic Resonator, and a Sorcer X4 within my system to good affect.
