But John, the graph you showed doesn't notch the 50 (or 60) Hz. It just lowpasses the first signal to get the second signal. That should be clear from even a quick look at the curves.
Noise reduction IS a Good Thing. But here it is in the mains neutral.
Question is what it does to the audio?

So what are you trying to say, Jan? That there are no canals on a Bybee Purifier? 😱

Well, I have stated what I can. It looks like we have moved to level 2. 'It exists, but it is not important,' ;-)
No, we're still on Level 1: what does that graph mean, what is it measuring, how is the "test" set up, who did it, what's the repeatability, is there anything unexpected?
John,
You may have noticed that I tried to ask reasonable questions about those graphs. If you have any knowledge of what they really are, about their significance, I would suggest now is a good time to tell us. 😉
jd
What do those graphs mean? How does this graph 'prove' that QP's work?
What is their significance? Give us some arguments how these graphs relate to the claim that QP's improve our sound?
Pretend you're a scientist who wants to explain to the unwashed masses what he has discovered?
jd
Even better, enough detail to allow replication- that's a sine qua non of presenting measurements.
Oh, you can read the graphs, then? That should be enough to show a difference with and without a Bybee device. The rest is only our imagination. At least, that is the easiest way to explain it. By the way, the input waveforms with the full signal, have a +/- 250V scale, the output waveforms are +/- 12.5V full scale, and it appears that the major lumps on the output waveforms are non nulled fundamental. All horizontal scales are 5ms/div.
Netlist, I hope that you are satisfied. You asked, I provided, and I have diligently attempted to explain the test. However, I did NOT do the test, I was not present at the lab that did the test, and I did not personally know Jack Bybee when the test was run. Other tests were also done, but they primarily show that there is NO significant capacitance, inductance, or anything else much, except for a fixed resistance.
When I asked, it was for the community.
I am surprised that it took so many years to reveal a tip of the iceberg.
I leave it to you to judge if others are satisfied but at the same time it seems that your aim is true. If you were not there when measurements took place, so be it.
On a side-note, I would like to say that it is most apparent that you come from another era, where designers and engineers used to be secretive. (My personal impression) Times have changed in this internet era and to gain some respect and credibility, one must be open when participating in an online community.
So yes, I am satisfied when you are less secretive.
Amen. 🙂

Just last night an engineering colleague, whom I worked with at Humphrey Ins and Lineage, told me that I give TOO MUCH AWAY. He now makes $125+/hr as a consultant, and until last month was temp employed at LBL. He has known me for 26 years.
Its up to the individual. Lets say that when you say A you should also say B.
Or else say nothing. 🙂
Now, what was inside of that QP when you pinched it? 😉

I agree; but I think I interprete that in a different way than you interprete that John 😉

One cannot explain everything. And sometimes, it is more practical to not give 'everything' that I know, for a number of reasons. However, with this Bybee noise comparison test, I would have posted it 5 years or more, ago, if I thought it would get a fair hearing. Thank you, Netlist, for asking the right question.
