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. đ
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.

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. đ 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  My advice to those that are interested is simply this â buy and try. Decide for yourself.  As Greg Voth from Stereotimes and others have mentioned â this is an easy A/B (blind or sighted). Plug in â LISTEN and then Un-Plug and Listen. Donât listen to me or anyone else â 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 â AND THEN â Mains with Deep Core  --- 4 volts on the line went down to 30mV. Proof is STILL in the listening and there are 100âs of Deep Coreâs out there. Popular product. |
@dogberry :
Nothing wrong with asking âwhyâ. Then itâs 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 donât understand your protestations. We are all adults, and can figure out what my work or not for us to spend the money. I totally donât mind reading other peopleâs experiences, just curious by nature, although I probably only take action on a very small percentage of what I read around the web  |
