Unclear to me how a badly written paper on 1/f noise mechanisms in nanowires supports any statements about Bybees...
What did the 1 ohm resistor say to the ampere?
"I am ready to kill a watt!" B'dum, dump...
Really - who does that guy think he is, anyway?
STOP MAKING SENSE
(Time out everybody - get outta that chair and DANCE!)
I have on file even better quantum noise papers, but they most probably won't fit in the message. You will have to find out for yourselves, if you want to know more about quantum noise. However, I did find the best picture of the inside of a conventional Bybee device and here it is. NOTE: It is a 0.025ohm power resistor. '-)

mmmmm huh ????
tunnel diodes were measured, understood, put into graphs, and defined their parameters.
according to datasheets, tunnel diodes can use as amplifiers, oscilators,mixers..
all we get from bybees, it´s just bunch of poetry talk
no numbers, no graphs, no load lines, no datasheets... how a sane engineer can use those?
sorry but i get feeling that this hiend "industry" is like : here, buy this super device, but do not ask much about it, you HAVE TO believe us it works !
I'm replying in regards to ferrite beads on audio lines.
My theory is that there is RF around us all of the time, most notably cellular RF but also television and shortwave stations, remember how high powered radiowaves can produce harmonics both in higher frequencies and lower frequencies. Well my theory is that the cellular towers can induce RF interference in the audio spectrum as a result of RF signals on the shield of the connecting cables. Ferrite beads can then remove said RF interference and shunt it to ground. BUT before they are shunted to ground they can affect the signal with an electromagnetic field.
If you are working on an audio system which is so incredibly sensitive that it requires thousands of dollars in components to have any appreciable difference then obviously RF interference could cause a great deal of headaches. If you aren't thinking in this way then you are thinking that audio signals cannot be affected by a radio transmission and so therefore you also think that you can put a high powered linear amplifier right next to your audio system and expect nothing to happen. This is the same thing except its much more subtle and the signal strength is much lower. The reason why the linear amplifier affects the audio system at all is because of the electromagnetic interference.
I have also noted that nobody here has mentioned or even considered the magnetic aspect of a radio signal. Magnetic fields can induce an electric current in any conductor really well. Yet we ignore this in audio applications. In HAM radio, antennas which use this property are very popular and perform amazingly well. But when it comes to audio we somehow ignore the ability of magnetic fields to affect our audio signals.
Think about it for a second, look at the size of your ordinary cellphone antenna on your phone, that phone can pickup a signal tens of miles from a cell tower. What makes a long audio lead any different? Its still an antenna, it wont be well tuned but it will still pick up RF interference from everything in your house, everything in every other persons house in the street including that plasma tv set down the street, that florescent light that has a nasty noisy switchmode power supply. etc.
What really surprises me is that people are still using unshielded cables going to their speakers. Just because we cannot hear the RF being induced into a loudspeaker doesn't mean that its not present and moving the voice coil, potentially causing distortion. We could at least put a twist into the wire going to our speakers but we don't, its just two conductors next to each other.
Just because audio frequencies don't 'need' heavily shielded RF-grade cable doesn't mean that you shouldn't use it. We are in an RF ocean and we are working with very low frequency very low amplification signals.
Now, the only way that I can explain why a speaker would require isolation from the ground would be so that it stands higher than anyone else and can look down on us acting all snooty. Either that or its because of subsonic/ultrasonic interference being caused by cars and trucks driving by. Something which I suffer a great deal from because I live next to a highway. But anyway the point is, ultrasonic and subsonic frequences can produce a harmonic in the audio spectrum. Yet we ignore that.
I'm not for 'botique' rubbish which costs $3k, I'm for the practical evidence-based solutions which cost a dime.

If you are referring to the Townshend speaker supports, they are tuned (ideally) to resonate at about 2.5Hz. The idea being to isolate any frequencies above that. They do work, stopping vibrations travelling into the floor, and in my house up the walls and keeping my wife awake! They also sound better than any other method I have tried. And no, I don't pay lots of money for them, I make my own. Less than £100 for a set of 8, tuned for 60kg speakers. But much less pretty! The old inner tube version worked too, but varied over time.
Oh, and having the speakers image from above my ears makes the experience more like a live performance, where the musicians are on a stage higher than my seat. I try to make mine so they focus properly in that position. It also works better when I dance around the room with the cat (he likes a bop).
YMMV of course.
Exactly.
If there were any physics to explain how Bybees work, they should publish it.
If, as has been said, it works and is unexplained as yet, they should say that, and provide the evidence that it does work.
Instead, they write a lot of pseudo scientific sounding guff, the only purpose of which can be to attempt to mislead the gullible.
If they are not honest, how can they expect to be taken seriously?
I'm not criticizing anything which works. I also wasn't talking about speaker isolation stands, at least not in the context of speakers needing isolation for the soundwaves that they create. I was more focused on the interference/distortion caused by external factors such as nearby roads. etc.
If it works by decoupling the speaker from the floor then I'm not interested, if that works then that works. I was detailing how a speaker could have distorted audio caused by the subsonic/ultrasound frequencies caused by trucks/cars/various other things in our environment. A completely theoretical exercise.
I was saying that the speaker isolation stands can work both ways.
An ideal loudspeaker would be floating in mid air suspended by magnetic fields. That way it would be able to reproduce the frequencies required without external influence/damping. But of course its much more complicated than that, specifically sound produced by a driver is reflected by the surrounding walls. etc.

Hi Scott , no but if you vist your local park on a really hot day you can normally find a few sun-dried dog tu*ds that will work just as well for a fraction of the cost.
Sorry if I have caused confusion; I'm just catching up on this thread. I was replying to nzoomed and his dismissal of the Townshend supports.
I will try to keep up. 😱
But they do also isolate from outside vibrations, at least within their range. So are useful under electronics that might be subject to such.

Not to jump on the beat the Bybee bandwagon, but statements like:
I'm pretty open-minded about snake oil products and concepts (e.g. enabl - which I haven't tried yet and about which I'm skeptical) and I tend to rely on my own experience rather than debates on internet forums, but I'm not going to shell out hundreds of dollars on something with such loopy explanations about how it works.
By the way, I read this on the Bybee home page: "and Bybee/Curl Pro & Signature power conditioners." Is this you, John? Do you, or did you, have a business relationship with Bybee?
are about mechanisms of functionality and imply that there has been some science behind determining that this is how these things work. So where is this science that has identified these mechanisms at work in these devices (devices that, in the next breath, are said to take advantage of unfathomable quantum mechanical forces)?

If you guys want to keep this thread open there are more targets out there, the pseudo-scientific drivel posted on Mr. B's site has been well covered over the years. I know this stuff offends many but he is not the only one and the little matter of discovery means none of this will ever come to any legal action one way or the other.
Yes, this was an embarrassing ad (for me) because I was not aware Jack was reviving a new version of passive line conditioner with my transient suppression circuitry in it, and adding my name (once again) to it.
I do have one of these units, actually the original prototype, given to me, after the product was discontinued. For the record, Jack is often giving me things to try, but this conditioner was a real surprise to me, and I must admit that I was blindsided by it. Yes, Jack would have paid me a nominal royalty ($5) for my transient suppression circuitry that I designed for him in the late 1990's with his insistence that no inductors would be used. It was a minor design challenge, but it appears to be successful to minimize line transients and even indirect lightning strikes.
I heard an 'explanation' that he was going to give me significantly more money per unit to help me along (I am not wealthy like Jack and his friends) in my old age, but I was never paid for it at all, and Jack gave me the prototype as a 'bone' for using my name and circuitry in the product that was discontinued because Jack claimed it was too hard to build and it was not really very popular with customers. Looking inside, besides my circuitry (all electrical, not electronic) there are devices that remind me of parts from the 'furnaces of the Krell' that look totally alien to me. Whether he personally fabricated them or bought them from an outside vendor is a mystery to me, but the unit seems to work.
However, I do not work as a partner or employee with Jack's company, and get nothing except samples from it. Sometimes I pay for the samples, but mostly he gives them to me. Over more than 20 years, the Bybee devices have piled up in my audio system. Any more questions?

I've seen a magnetically levitated speaker advertised, but don'tknow where I'd find one to listen to.
30 odd years ago, I lived about 500m from a railway bridge, which elevated for ship traffic, when needed for ships needing more than about 7m of clearance.
Sometimes deep sea vessel operators, or their pilots, would forget to switch to lower power transmissions, in these cases, I'd get to hear loud distorted 1/2 conversations blasing out of my system: Vancouver Traffic, Hecate Straits. Traffic, we are 10 minutes out, can you lift? Traffic, Hecate Straits, copy that. Will hold against tide for lift.
Copy 20 minutes. Advise when trains clear. Straits out.
I also lived 2 blocks from a stereo store, and the salesman was selling me power filters and shielded cables when his manager walked by, having overheard the situation. He advised me to go find ferrite clamps at a Radio Shack, or electronics store, and put those on all my cables, power and signal.
Only a few bucks back then, to do my receiver, turntable, and vcr, and lampvord speaker wire.
Never had the issue again.
Ferrite clamps are dirt cheap, still, and I still use them on my speaker wire, whether they block noise or not, I don't know.
