I am saying that the BB's actual effect may be out of audio band.
I concur, assuming that it does indeed have an effect on signals and not just on perception.
Why not do some higher frequency measurements to characterize them fully ?.
What kinds of measurements do you have in mind? Care to be a bit more specific?
Again I have to ask why this wonderful! device is only available in Audio circles (or should I say from a limited numer of purveyors in avant garde audio add ons). Why is it not available in other realms of electronics.
Of course the basic part in its unclothed version is available en mass, but when it gets its emperors cloak it seems to disapear from mainstream electronic!🙂

Not sure. Sweep them out to GHz range ?.What kinds of measurements do you have in mind? Care to be a bit more specific?
Network analyse them out to GHz ?.
Do the same with the internal resistor and compare measurements to a BB assembly.
Eric.
Sweep them? Network analyse them? So far not enough detail to get a handle on what might be seen...
Myself I have a hypothesis that they might be RF absorbers at very low levels of signal, a bit like ferrites. But I haven't much of a clue how to verify that. Which is why I asked you....🙂 So far, seems you haven't either. Never mind.

I mean sweep them to look for absorption and/or resonances.

RF absorbers or attenuators?
There is an RF absorbing material come out recently, but it works on the same principle as fettite bead, converts the HF stuff to heat.

Gentlemen,
I just stumbled onto this thread.
What were the results of the measurements?
I am hitching to buy this product or the nuforce.
Would you know if the carpet cleaner 1001 is still available? I think it is best to re-orient the carper fibers before laying speaker cable and ByBee or nuforce on it. 😀
Aaah! the improvement of snake oil through magnetic fields.
Cheers,
Serge🙂

Which would tell you what, exactly? Compared to what, exactly?
Instead of throwing out vague speculations with no connection to any evidence or well-established phenomena, get off your lazy butt, lay out your own money, and do some actual research. If you think that gigahertz stuff is important for audio and that these vinyl-dipped resistors have some measurable or verifiable audible effect, go get some evidence. Otherwise, you're just blowing the same smoke as Curl.
The last time you were making wild claims about things you could hear (cable directionality), you disappeared when it came time to put your claims to the test, after Steve Eddy went to the trouble and expense of preparing samples for you. Can you man up and do some actual work this time? At your expense, of course.
I disappeared because of a fractured vertebra, no other reason Stuart.

We have a very gracious offer here so why not take advantage of this offer and see if the BB's do behave differently to the internal resistor on it's own....what's to lose ?.

I had offered to run RF parametric measurements on them since some of the early claims kept referring to magical properties in the several GHz range that influenced the sound. It now appears that those measurements are not needed, but I can still do them if needed.

I understand that scanning and posting aren't things you can do (that's OK, there's a whole 'nother thread on my computer stupidness, we're old), but could you verbally summarize the test setup and conditions, and then the differences between your measurements of the Bybee and a normal COTS resistor?
Also, since your measurements are 15 years old and the devices seem to have changed since then, do you believe that your measurements are at least qualitatively representative of the Bybees as currently produced and sold?

Oh my freakin' god.
Ahem. A Cray supercomputer.

(recovering composure)
So, it measures like an ordinary resistor.

Are there any more recent tests with results that you know of ?.

Eric.
So it does nothing at audio or AM frequencies. What about FM, Wi-fi or mobile frequencies? If it does something to the electrons, then it is either an impedance or a Maxwell demon. We can test for the former. Instrumentation for the latter does not yet exist, on the grounds of nonphysicality (e.g. second law violation).

He must have meant Cray Y-MP. A resistor yes, makes heat. I promised JC I would not jibe him anymore, I just wish the 40yr. circuits could get some serious updating.
Wheres the energy stored it converts to heat, or do you mean it resists the flow of current going through, the effect of it resisting this current flow is the generation of heat.
Cable directivity!!!!!!😀 that still a belief.
Again why is this wonderful device only available to the esoteric audio fraternity.
