The best plug in filter ever!

I ran it in G*Power, and for my test to be validly predictive of the entire population of listeners, it would need to include at least 89 men and women who were randomly selected. Otherwise, my test results are only going to prove that my wife can (or cannot) clearly hear the difference that it is making in my system. She will also have to listen to at least 30 different sets for me to be able to calculate the correlation strength. But again, this is all being done for fun. 

A. If my testing says that my wife could not consistently detect any difference in a double-blind test, then all the Puron nay-sayers can post pictures of snake oil in here and all of us who bought will just have to endure it. 

B. If my testing reveals that my wife can consistently detect differences with the Puron in the double-blind test, then the nay-sayers will all have to wear paper cone hats for a day and go and buy a Puron in penance. 

Just to put a little hole in your test. I have found that random removal and reinserting the Puron’s to be very difficult to discern differences. It takes a few hours for the full effect.

How will you account for this with your tests?

But I think if you can get your wife to sit still for a couple of hours then remove the Puron she should notice the difference.

Perhaps try using video instead, the eyes can clearly see the improvement in colors, sharpness and depth.

"C'mon man!" LOL 

Yeah this is probably a bad idea... my wife is going to ask me questions about how much various things in my system cost. 

Best to keep them happy in other endeavors.
