In my understanding of standard signal theory these additions should have no effect, but they do.
There are other many and varied applications I have trialled with similar effects...ie quieter, clearer, more stable operation of systems and devices.
Something very curious is going on and placebo and expectation bias are most certainly not involved.

Curious, how can you design something you don't understand... sounds very Bybeeish.

Maybe we can repeat the Studio Magazin Bybee test and characterise my filters also.
I am awaiting reply from Gecom on details of their experimental test setup.

Yeah, working with 6GHz will show some effect in almost any component, maybe you should look at the complexities of RF and microwave design.... of course how effective things are at audio frequencies (even digital audio) is a different kettle of fish. Make sure you use step parameters as well, that really makes me laugh, as you and others moan on about how sine waves have no real correlation to real music...
Keep on playing boys I find it so amusing after so many years... keep the acolytes happy.

By being very aurally observant and seeing reasons/correlations for Sony, Pioneer, Yamaha etc 'house sound'.
Long process of AB comparisons and experiments to deduce common factors and fundamental differences.
I also had conversations with a retired nuclear physicist who confirmed each of my seemingly weird findings..."Yes, expect it" was his repeated reply.
So now I have gotten toward the end point of trialling, now is the time to formally characterise and hopefully explain what is going on.
If what I have is indeed measurably improving noise floor of all manner of elecrical/electronic systems then that will be for the benefit of all.
As it stands I am getting audio system subjective results similar to BQP, retailable at a tenth of BQP price and mega mass producible.
Midfi, hi-end, pro audio and muso trial users have been consistently highly enthusiastic and zero objections.
Recent muso comment was "I didn't know I need this, but I do know now".
Marce, I respect and acknowledge your knowledge and experience.....this is something out of left field.
It may be loading of and quenching of induced RF noise, it may be a dithering function in analog domain, however whilst on cables works well, placement on/within chassis has same audible effect and in accordance with descriptions of Bybee plate device.

Marce, I posted a translation of Studio Magazin BQP test report.
Please read it and tell me what you glean and by all means point out errors/omissions please.

Dan.

I tried to read it, my comments were put up earlier... tests inconclusive, graphs not clearly labelled and S parameters used for testing.... #10433

Basically the measurements are quite easy:
First You have to prove that the bybees behave in the audio-frequency band like a piece of straight wire.
IŽd use an impedance analyser to show R, Z and L.

The next step is to prove, that they work for hf suppression. What You want to show is, that intermodulation products from hf are reduced in the audio band.
You need a kind of test fixture.
Insert a straight piece of wire in the signal path. Take a good spectrum analyser and feed it with a noise source.
You will get one trace - normally flat, generated by the noise source.
Than insert the Bybee instead the piece of wire.
The trace will show some significant reduction of noise in the audio band, up to 10 MHz.

Best regards
Stephan
Comments please.

You are adding a resistor.... so need to do the tests with the same resistor in its bare state, that is the only way, not a piece of wire.
Noise in the audio band up to 10MHz my god but some audiophiles have some excellent hearing.
Finally I occasionally work at a firm called Shimadzu research laboratory, once discussed the famous Bybees with one of the guys there, he laughed so hard I though he was going to have an accident... Bottom line load of marketing BS and a resister wrapped in ERS cloth or similar, if they did work he reckons it would be nobel prize material...

It is sad to see intelligent people promoting so many audiophile BS products and myths, but it helps keeps the money rolling in!

well for a start 10MHz is not the audio band.
secondly his mail is total BS. He talks about getting reduced HF IMD but then talks about measuring HF noise. an IMD test is an IMD test. A noise measurement is a noise measurement.

Oh and a there are perfectly good and cheap products for reducing RF noise.
