Default Analyser Analysis...

I have not yet read the operators manual of the SR-1, but I do have some limited experience of the Prism dScope Series III analogue and digital audio analyzers.
Interestingly and usefully this test set can discriminate and display seperately Noise and THD.
Also useful is a multi tone IMD test with selected non harmonically related frequencies.
Worth studying the manual.

Sy, if you still have the magic stuff, Bybee pretend its device remove IM. Can-you measure any IM from the out of an amp, with and without the magic device ?

Sy,
Since you have one of these devices have you attempted to disassemble this trick piece of electronics to see what is inside? Wouldn't that settle what magic elements are inside the wrapper, whether is is nothing but a straight piece of wire or even a resistor? If it is epoxy encapsulated that would be fairly easy to dissolve off of the internal structure and see what magic fairy dust is inside!

Name the frequencies and where you want the "devices" connected. It's easy to do. I looked at noise floor with test tones, with (of course) no differences. Understand, of course, that even with an IM measurement, some magic force will be invoked that test instruments can't see, or the measurements will be fatally flawed since the "device" was put in the wrong place to make it work (the application instructions are vague about where they should be used and John won't suggest anything helpful), but at least it'll be useful for the rational folk.

They're not mine so I won't disassemble them (they were bought by Cal Weldon). Others have and found some stuff wrapped up around the resistor. Apparently, the wrappings are just a sideshow since there is no electrical effect. My own feeling is that it doesn't really matter what floobydust is packed in there, they either do something or they don't. And since they don't, the floobydust is not terribly interesting.

Default Qualified By Experience...

My job in life is to make the best audio equipment possible, even if many here think it a waste of time and money. In the past, I would try just about 'anything' after learning from experience, that something denied or neglected today, just might be found of use to make better audio quality equipment. This has been so for me with connecting wire, connectors, circuit board material, caps, resistors, etc. etc.
I use what WORKS the best, not the most expensive or the most pretty package.
....Are they crazy? I don't think so, they just trust their ears. It actually works well when one can keep an open mind about this stuff.
Yup, I have learned by experience for a long time too.
Servicing and listening to a million bits of gear made by a million different manufacturers allows one to see (hear) some very interesting correlations.
All is not at it seems on first inspection

So after (or indeed before) you did your measurements testing, did you try subjective evaluation on at least more than one audio system ???.

Hey Sy, we get it, we get it, we get it!

You've put the data out there.
We can connect the dots ...


No need to ... tinge the ... flavour of your posts with such ... unflavourables!
It reflects unfavorably on the ... cook.



PS You write better when you have to ... stretch for polite words

John,
We all by now should understand the placebo effect in medicine and also here in audio. If you want to believe that you hear something you will hear it even if it is not there. There are proofs that placebo's do work in medicine, the mind is a very strange thing and we can even believe ourselves well. That is a very powerful argument for the fact that some will hear something even if it is not there even if you could show that it truly isn't.

Actually, the proof is in the testing.

Scope photo's have been provided as proof of an effect.

Why is there no information made available regarding the test setup such that others can duplicate the test???

Results which cannot be duplicated by others is indeed floobydust.

When the origionator refuses to divulge the setup or test conditions so that the results can be checked, there is another name for that. Scientific misconduct comes to mind as one possibility.
