Max, I haven't followed everything that you have inputted here on Bybee devices, but apparently you have tried them too.

Yes, I was given three of the Large REGULAR Quantum Purifiers...2" x 1/2' with the Pacific resistor inside....2 intact and one dissasembled, thank you Mike Bettinger, RIP.
I have tried them in all manner of situations and I hear them perfectly clearly, problem for me is that they impart a signature over everything that is ultimately not to my liking.

I have also trialled these....Black Discus sample copies (thankyou to MSA) and these have another effect that I am ultimately not keen on....quiter, better damped but with a Musak quality to everything with these in the system.
With the BQP's I find lowering of noise floor also but with a different 'wrong' decay sound which also becomes identifiable as a signature that eventually 'drives me out of the room' (Thanks Jocko)
I am only able to say the above because of my adventures and experiences with my versions of this 'filtering'....lower noise floor, better clarity, dynamics etc but above all 'groove' and 'fun' factor in music is restored big time and to my ear unlike the above examples.
This perfectly 'portable' solution does not really have a signature...the system signature is revealed when the filters are removed and absent with the filters....music emerges from pretty much anything, high end and PA sounds like it should.
I am yet to find this treatment tiring, or boring or annoying etc....I find in fact the opposite is true in that systems don't sound 'right' without it.
I have not grown tired of the 'sound' of my version in all manner of trials from bedroom radio to full on club PA system...stage/back line, mix desk, PA amp rack and speakers/monitors inputs...and a bunch of arena/stadium system secret AB trials on power and/or multicore.
Those who are in the know really dig what it does to live sound, audiences unwittingly, I also have pro guitarist and bass player using these long term.

I was also skeptical at first, (20+years ago) but I trusted my ears and then went to find the source of the devices and I certainly showed to myself how a typical physics education barely predicts what is possible.
Sure. I noticed interesting/curious effects long time ago, and this has led a long path to where I am at now.


Of course Jack's 'devices' have changed over the decades. These days he is most interesting in a new material that when put in proximity with active devices, seems to improve the sound through them.
Sure. Been there, done that, still doing it. 😎
I have a bunch of other versions/applications well proven.

I first tried a version of this material with my OPPO 105. NOW, it is more listenable over a longer period of time, without any other mods. Jack just bought an OPPO 205 and he has improved it with his new stuff as well. We have a third colleague equally involved who has more degrees in both physics and electronic engineering as Scott and me combined, and he is just as enthusiastic.
Or just as deluded as the rest of us. 😉

He was the one who thought that the Quan-Tech could measure something definitive, but alas, it did not. However, he and Jack drove an hour to try it on my Quan-Tech just to see for sure. In reality, we still do not know EXACTLY how these new devices (or process) work, we just know that it does.
I'm having the same troubles...perfectly audible but I don't have definitive measurements...yet.
It'd be interesting if you were to describe what JB's new gadget is.

Dan.

Jack's new process is a material that seems to effect audio equipment around it. It is usually pressed into being a layer of what looks like a thin strip of modeling clay, but is usually black or grey in color. I have some stuff here with sticky tape on the back. It seems to make digital more analog sounding to me. I will try it next with the STAX headphone driver (tube) that I use as my listening reference.
I too have been disappointed at times with the Bybee devices, but the important thing is that they do SOMETHING, sometimes significantly removed from the circuit itself (the latest process does not need an electrical connection). However, WHY does it sometimes make things sound lousy? Even embarrassingly so, sometimes.
In my opinion this is a whole new physics that nobody normally knows anything about. Just like 'dark matter' or 'dark energy' were 30+ years ago when I learned astronomy, and how the universe works. Black holes? They are sort of new too! '-)

Who do you think you're fooling? Black holes are not that new in any case. Having participated in real physics recently, this stuff is not even at the level of a good joke. Now no electrical connection, "spooky action at a distance". :rofl: :rofl: :rofl:

I have similar form factor that can be moulded to any shape.
I find everything sounds more analog, and especially useful is that older recordings that are 'suspect' (lots of sixties, 70's rock/pop etc) come to life and noises and distortions don't matter anymore.
Good and really good recordings become magical.

It seems to be to do with intrinsic noise...and yes proximity effect of some sort seems to be the root.
It seems that our ears are more discriminating of low level information than is generally given credit for.
Some sounds just don't go together, a bit like cables can make or break a system, or different film caps that sit 'right' or not. ,

Yeah. I have wav files on my HD that sound different according to whether I used OEM cable or my own custom cable to transfer to a thumb drive and back again.....certainly my USB sound card sounds different with a custom USB Male/Female extension in circuit.......something curious is going on at a deeper level.

How about sending those out like Mooly to the unwashed masses for a listen?
 
Jack doesn't have a Bentley anymore. We now have to jump on Richard Marsh for owning one. '-)
Jack told me that he is too old to really enjoy the extra power that he had (650HP or so, yes he re-chipped it) so he sold it and now drives a similar Korean made car that is very quiet and comfortable. He gave me a ride to the restaurant in it this week. Jack has made very little money in audio, he told me that he bought his Bentley from earnings in the stock market several years ago. He just does audio to keep busy. No, I am the guy who needs to design audio stuff to make a living, and fortunately it keeps me busy too!
Scott can now retire and find out what it does to him. I have been on SS for 10 years now, and I am glad to keep working, at least part time.
Jack works far harder than me, and he is 13 years older. I think he just wants to get out of the house and fool around with new technology.
 
This week, I had Jack Bybee over and we ran some tests on some of his latest stuff. It did allude to noise measurement, but we still can hear the difference, so we are still looking as to why. We are actually working to improve even the best audio systems, and to a great extent, have succeeded.


On a standard engineering topic, Jack gave me a METCAL soldering iron and several tips. I find it a serious improvement over my Weller irons that I have used over the decades. Anybody else here use one?

I have been using Metcal's for 25 years. I have about 20 different tips on hand. Its hard to improve on the design. I have a Metcal desoldering tool but don't use it much. Too much hassle for a few connections. However a hot air tool is really useful as well. I have recommended them several times here. EBay is the only way to buy them.

John, do you have a resistor noise test set? If the Bybee's make a tangible different it should show up there. It would be an interesting spin on the fundamental physics if they could reduce the thermal noise of a resistor. Let me know if you want to try them on the Quantech 315C or the RE CLT-1.
