Can you use the Puron in conjunction with the add-power eau2?
Has anyone did a direct comparison?
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.

@normb thanks for the link. Good candidate. Also at $250 but without 30-day home trial. Anywho, Puron still rocking the house… beautifully. |
@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. |
@dogberry 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”? |
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.

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? ozzy |
So this isn’t a “pass-through” unit, but goes into another wall socket? “I have used Puron in the same Duplex that has the Mains for my Core Power 1000. I’ve also used two Purons – in that same Duplex, as well as Position One on the CPT 1K.” I’m obviously missing something here, inferring from previous comments. thanks. |

Audiogon Discussion Forumworks! Holy $hi#! This thing actually works! @shkong78 this thing is legit. As someone who has posted asking for help trying to get rid of very low-leve...
I did not have much problem with hiss and noise. |
Nothing wrong with asking “why”. Then it’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 don’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 don’t mind reading other people’s experiences, just curious by nature, although I probably only take action on a very small percentage of what I read around the web

@dogberry
My advice to those that are interested is simply this – buy and try. Decide for yourself.
As Greg Voth from Stereotimes and others have mentioned – this is an easy A/B (blind or sighted). Plug in – LISTEN and then Un-Plug and Listen. Don’t listen to me or anyone else – Listen to YOUR System.
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 of Mains itself – AND THEN – Mains with Deep Core --- 4 volts on the line went down to 30mV. Proof is STILL in the listening and there are 100’s of Deep Core’s out there. Popular product. |
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.
Ah, the secret technology. Well, of course, now we shall all believe. 😉 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! |
@clearthinker
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. Welcome to contact me at verafiaudio@gmail.com or (818) 584-6870 |

@dogberry You are right. All the others are wrong. But they are not harming you, they only harm themselves and make tweak salesmen rich. @corepowertech Please say how this mains filter 'deals with timing'. Please say how it achieves 'an improved retrieval of information'. Sounds like it's you that's selling it, so you must know. |
My own experiences re Puron I have used Puron in the same Duplex that has the Mains for my Core Power 1000. I’ve also used two Purons – in that same Duplex, as well as Position One on the CPT 1K. Just closing by saying thanks to those that have supported me and the products I’m involved in. Those not interested – I understand. |
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.

@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 it’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-1260’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. |
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.

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 “The first principle is that you must not fool yourself—and you are the easiest person to fool.” 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?
|
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. |
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? |

Purons Update: Well, I did it guys. I unplugged the Puron off the system and wow, is this how I enjoyed my music before? Almost instantly, the soundstage starting to collapse. Imaging starting to wash out and smeared not a whole lot but most definitely noticeable. Tonality shifts up a bit and becomes slightly brighter and scratchier. Purons seem to work for me up to this point. |
