The best plug in filter ever!

But for her to notice the video improvement, that really says something.

I am assuming she was testing video completely blind, right? Blind test ABX? 🤦‍♂️😉😂🤷‍♂️

Even n=1 blind tests are effectively nullified by the (clever*) statement that it takes 45 minutes or so for the effect to be apparent.

45 minutes ruins our ability to compare. I'm trying to keep my 17kCDN electrostatic speakers going despite their 12 panels failing, one by one. Each time one fails, I substitute a pair of boxless transmission line speakers. First disk I grit my teeth. By the third disk I say to myself "I can live with these—why am I repairing those expensive speakers?" And after repair, I say the same kind of thing to myself in reverse "This is so much better" yet by the third disk I can't remember (other than intellectually) what the difference was. Only do I find support for the better speakers in long term usage: do I choose to spend my days listening, or doing something else? Do I find myself staying up late at night for just one more disk? That's why I am going to replace all the panels in those speakers: they keep me listening. In just the same way, it would take months of honest self-reporting to do the same with a device like this. But, read on, if you like.

*clever? Well, certainly. It means you cannot conduct any kind of blind test for yourself, as 45 minutes means no worthwhile comparison. If you want to argue about that I have a solution for you. It will take a few weeks and need a helper. Let me suggest a couple of weeks with the device plugged in, and a couple without it. Record your satisfaction each day. Your helper must not tell you whether it is plugged in or not. Do this for about three cycles both ways, which is six weeks. You must not cheat, so the device must be hidden from accidental view. At the end your scores should be analysed, along with those of (as many as possible) other listeners doing the same thing. An independent examiner will take the results and the information from the helpers which says plugged-in or not-plugged-in for each set of two week scores. Then, and only then, will you know whether you are listening to a real effect, or your own expectations.

Many people will say none of this is necessary. My answer is why not do it—properly, with independent oversight and analysis—and prove me wrong in my suspicions? There's nothing to lose if you are right.

@dogberry : no need to get worked up and write a whole thesis. It was a joke to Ozzy. Watch video blind. Get it now?

Greetings to all,

It’s been a long couple of weeks. I replaced my MIT Z Stabilizer conditioner with a Audience Forte V8, replaced the 2 MIT AC filter outlets for my amps with a hospital grade outlet for the subwoofer amp and a Furutech GTX NCF outlet on the Main amps.

I listened to my system for 5 days (without the Puron filter) listening to the same 5 CD’s and 4 albums over and over again. I made notes while listening. My system sounds very good to my ears.

 I then plugged in 1 Puron filter into my front end equipment. I have been listening to my system this way for the past 8 days, listening to the same CD’s and albums over and over. I’m happy to say the Puron filter is doing No harm. I’m not hearing  all the other improvements that other have heard. I believe that since I already have good AC Power coming into my house, I already have a very quiet system. I have 3 of my circuits on their own isolated ground system. No hum, buzz or hissing comes out of my system.

 The 1 thing noticed with the Puron filter is on 1 of the CD’s the background singer is now more in the room with the voice much more pronounced. That’s a good thing.

For now the Puron filter will stay in my system. In a few more days or weeks I’ll remove the Puron filter and see what the system sounds like without it.

For right now I’m Tired of listening to the same music over and over. I will play something different today.

 I think the following might have happened when I didn’t get positive results the first time using the Puron filter.

The MIT Z Stabilizer was not compatible with the filter?

Having 2 filters plugged in at the same time overloaded the system?

The Puron filters I have needed to be broken in longer than others have experienced?

For now my system sounds Great. I’m happy with my system.

@ozzy I never heard a AC conditioner that I liked. I always thought they did more harm than good. Have you recently removed your conditioner from your audio circuit and just plug your equipment straight into the outlets? I know you have very nice conditioner’s in your system. I have never had that brand in my system. Maybe give it a try.

 I’m going to listen to some different music now. Have a good day.

joenies,

I commend you for sticking to it. I know what you mean about playing the same music over and over, it can get old fast.

I also agree that most power conditioners due more harm than good. Except the Niagara 7000 even when used with my mono amps there is a big improvement.

But originally, I did not like the Puron’s plugged directly into the Niagara. Perhaps I didn’t give them enough of a chance, so I am going to try it again.
