A $250 Power Conditioner?
Howard reviews the Puron, which is a small AC power conditioner ($250 USD) "plug" that is distributed by Vera-Fi Audio. It’s said to cleanse the electronic circuit that feeds and audio system. Many tweaks cost a pretty penny for little or no performance increase. Is that the case here?

@questforhifi , I do not notice any "brightness" that is not on the recording itself. I understand that it seems to go away when you remove the Puron, but all I can tell you is that I have not noticed anything like that in my system and 2 of them have been in my system for a couple of weeks now. I am still a happy camper with them and while I wouldn't say that it is a "blow me away" improvement, it is a noticeable improvement for tiny comparative money. |
Questforhifi the brightness I suspect it coming from Nordost cables , if you put Puron the Puron will give more energy to the instruments and voices? The tensions you are referring is the energy ? My friend experienced i brightness as well to his system.He replace one of his cable to match, He is now happy. Milpai is right . |
I am planning to get another one and check out for myself.
I am trying to understand what you mention. If Puron adds it’s own noise, how come more details are revealed, sound stage seem to expand in all directions, there is an increased holography and music in general seems dynamic. Something else is going on here. Not sure what it is though. |
I will say this as someone who only uses a single puron It does make music sound more real. You would have to hear it for yourself. I have very expensive electronics. Im very fond of my stealth audio and nordost cabling though-out and i love my synergystic power conditioner but none of them ever made certain songs sound so realistic. my only complaint, which is a rather large one, is that some songs sound too aggressive/ bright with the puron vs when i take it out that tension seems to go away. But like i said its not for all tracks and my wife hasnt noticed (but im very sensitive to it)
the cool thing about the puron, its VERY noticeable in effect. Something unbelievable for only $250 this is not something where you have to say.. hmm well i think its doing something? You dont have to a/b it, the effect isnt subtle thats why i like it but its not a true power conditioner in the sense it will do anything to actually filter your ac…. Which is a good thing because like i said earlier thats a very expensive endevour and most products that try to do so struggle and this includes both the p20 and also the entire line from stromtank which can be in the tens of thousands of dollars for some models from what I understand this actually tries to override noise with more pleasant noise (some noise sounds good to the human ears) which is possibly why the guy with 8 of these is getting high noise readings
finally to touch back on the brightness topic. Im not being completely fair to rhe puron. Its just one piece of a larger system. Im due for a dac upgrade. I think the mola mola tambaqui will help smooth out the sound and give me what i want. Also i have been using a generic ethernet cable for streaming. Im sure when my new cable comes things will improve even more |
It’s pretty rare IME that a “tweak” — or anything for that matter — gets such consistently strong reviews. Townshend Seismic spring platforms/footers are one such example, but these are quickly moving toward making that elite list especially given the relatively low cost for the meaningful benefits they seem to provide. Thanks for bringing these to our attention! |
Question to Puron users: I have only 1 Puron installed on the empty port in the 20 amp dedicated line that feeds the power conditioner. The other 20 amp dedicated line is used to power the brick that powers my audio server (windows machine). Since it is a SMPS, I am wondering if it will benefit, by adding another Puron on that empty port. Thoughts? |
After readings a few threads on the Puron, I purchased 2 on sale. One went into the wall with the Shunyata Alpha V1 power cord from my Pass 205.8. The other went into a 500W isolation transformer into which my DAC and pre are plugged. I found basically the same results as others . . . better detail, better soundstage, slightly better bass, and the instruments seemed to have more air around them and were more precisely placed in the soundstage. Confirmation bias? Who knows. But to my ears, it sounds better, and for small money. As for those who rag on this product without trying it, I understand the jaded skepticism that many naturally have. But there are a significant number here who have them and like what they do to one's system. In this case, with a 30 day money back guarantee, put them in your system for 21 days and if you don't hear a difference, send them back. But don't say without trying them that they "don't work" or I "heard that this is what they do" |
@milpai Glad to hear, and way to keep an open mind, try new things, and have the confidence to trust your own ears! Now you get to reap all the wonderful and ongoing benefits of that. Hopefully the Flat Earthers will stay away from this. 🤞🤞🤞 |
@jayctoy , I did get one a few days ago and I was astonished. I was not ready for this kind of improvement it brings. A cursory information of what this thing does would have been helpful, instead of thinking that this filter adds some pixie dust to music making. BTW I have added Puron pics to my system. |
Milpai read the OP thread , He has a good description what it does.Adding 2 more Puron total of 3 on my system. To my surprise it made more music more energetic involving, flesh out more music , smoother and still remain natural and dynamic., Milpai Verafiaudio has 30 day trial. My bet you will keep it and order more. |
Of course, I didn’t expect anything fancy from this iFi purifier, like i do with my AQ Niagara. But, it did some resolve a couple of issues with my monitors in my PC Audio/Office rig. Your mileage may vary depending on the default state of power quality in your house. For example, here’s some dude on YT showing a demo of it in action (4:25) for one problem.... https://www.youtube.com/watch?v=X5V1JOSjbRA Later on, i discovered that there was a malfunctioning dimmer switch hidden away in my spouse’s adjacent office room injecting noise. Any audiophile should get dimmer switches completely out of the house, or, at the least, put them in a fully ON/OFF state. After such noise culprits are systematically eliminated, one should just get away from these type of bandaids and install a proper dedicated line and install something like a Niagara. If you need to break through a lot of drywall, etc, just move other lights, appliances, etc in that line to a different line, thereby, making it a dedicated line! The Niagara, ime, is the best thing that happened since sliced bread for hifi. The reserve/supplemental current it holds/offers for some demanding tracks at high enough SPLs is even better than plugging amps into the wall (common tribal knowledge), whilst protecting all your amps. i.e., Niagara is better than wall for your high current amps. Power Regenerators (PS Audio, etc) = current limiting, no matter what the marketing is.. I haven’t seen any practically sized power regenerators with transformers huge enough to prevent that, if you have a big enough amp at high enough SPLs...it maybe works ok for dinky amps/flea watt amps and just other sources. P.S Ah, it does appear that my post from last night looks "too exuberant" by normal Agon standards...could have been the Bourbon. |
The iFi is only 110 dollars!! I could buy two iFis and a bottle of whisky for the price of a Puron!!!! Why the hell would i buy a Puron?!?!?! Sounds like you boys got Puroned.."
Well you won’t know if one is better than the other without comparing - maybe you got "IFI’d". Puron and Shunyata Defender are both better than the NCF Clearline in my direct experience. Point don’t criticize what you have no experience with |

I have one of these Entech noise analyzer that I purchased maybe 2 years ago based on a previous discussion, so I tested things out. On setting up on an unfiltered outlet, it would only have an affect from the one Puron that is within 5 feet of my breaker box and not on the same circuit. On setting it to about 100 it was very quiet with only hearing a faint radio station with extremely low interference. Nothing like the unfiltered noise level on the video. Kind of needed it in a headphone position to really hear it well. I then went to the one circuit for my system which currently has 8 Purons on it and the reading was actually higher at 127. It was still very quiet but higher! I then went to my Uberbuss power conditioner which is on the 8 Puron circuit obviously and its reading was 13. That was a difficult position for me to be navigating in so I only listened quickly and didn’t really hear anything in the couple seconds. In the who cares department, on my unit when you overload it that small round spot parallel to the volume adjustment illuminates red. Having watched the video I don’t believe his lit up. Not sure why. Also, I don’t think silver cabling has much to do with varying results for the auditioner. I have Duelund 3.0 silver foil speaker cables with pure silver Aero spades, Kimber KCAG interconnects, Kimber D-60 digital cable, and Lavricable Grand power cords, two of them. All pure silver cables. The only connections that are not silver in my main rig is the umbilical from power supply to my transport, and the 3 Signal cable digital reference power cords for my transport and Dac going to my Uberbuss, then to wall outlet. I plan on continuing to add and subtract the Purons I have along with varying locations to hopefully achieve the best sonic results for my application.

Brightness city wow
its like taking an equalizer and going +9 db to the treble i can understand why you guys like this, but it does NOT mix well with silver speaker cables i had it plugged into wall next to Galileo sx power cord. At first i liked it, and immediately thought it was a positive improvement I’ve spent the past week trying to figure out what’s wrong with my system and what was causing the unbearable brightness. I tried everything, finally i removed the puron and immediately my ears stop ringing. I now realize the puron has simply just broken in. The first day or two i was just getting a little bit of the puron and it was good. Now thats its broken, its just too much
i decided it give it another shot, this time in my power conditioner instead of wall outlet… its the same thing.

@lpretiring there are countless posts on various forums about 'power line conditioners', 'power line filtering' devices, to include the one I mentioned. They all perform the same function, and they all make the same claims, and they all make same/similar demonstrations with same/similar "reduction" in AC power "noise". These devices have been around for decades, and they all perform the same function to varying degrees of efficiency and varying degree of effect. So, you can spend $200, or even $2000 and likely higher on a gadget that does the same function of a $35 gadget. Maybe the materials are much higher quality....maybe that in fact makes a larger "impact", or efficiency, or SAFETY.......maybe that "impact" is audible....maybe that is worth the cost of the device. For me, I would try something cheaper first to try out, listen to hear if there are improvements and get some scope tests done to see if at least it is "cleaning" the power coming from the wall, before I would drop $200. |
@tablejockey the QRT does work. My neighbor has 4 in his system. They work quite well, have you ever tried them? Read any of the reviews and tests? |
I haven’t tested this product. In general i think that trying to filter noise from a 60hz power feed is a losing game. If you actually get it done, you limit power. but I have an open mind. Maybe some alchemist will figure it out. Here is the before and after oscilloscope shots of my ps audio P10. I wish every product that is designed to improve power would show these graphs.
