From what I understand, some or all of this material is quantum.

What does that word mean to you? Are there materials which are not "quantum"?

Now do you deny that quantum materials exist?

Until you define "quantum materials", yes I do.

Quantum mechanics is pure magic.

Who told you that? Quantum mechanics is pure mathematics, there is no magic involved. Read a book!
 
I would like to know adequate for what? Most of the time here is spent arguing about how "text book" theories don't help design for the "best" sound. Is there a book of theories on that, I mean theories in the classic sense?

I did fall asleep in Millie Desselhaus' quantum mechanics class and I'm sure that's part of my problem.
My concern is that some will attack what was taught simply because it may not support predetermined notions. "While I am an engineer, those who do not agree must be retrained...."

I find that emc, ground loop theory stuff wasn't taught back in the late 70's, but it is firmly grounded in e/m theory taught then. I guess I could take the "high road" and say theory back then is inadequate... But that would not be accurate. It certainly was, but the application wasn't done.

The degree is about learning the fundamentals so you can apply them.

Compared as in listened to them. I know, it's a very unpopular concept.

But I did with my own money. More importantly there were the claims of "quantum" improvement of anything even the cheapest computer monitor just by proximity. Nothing, and visual things are far easier to A/B. BTW there are Bybee distributers in countries on the list of where a lot of hi-tech IC's are banned for export. The military secrets thing was a nonsense from day one.
 
And there was no measurable difference in their properties or response? You measured their values (C and R and L) to verify they were the same within, say, 1%? You looked at their coefficients and operating points? If they really matched that closely on all major parameters, then to what do you attribute the difference? Do you think it came down to things like construction quality and microphonics? Do you have some other explanation for the observed difference?

Capacitors of different types tend to exhibit different amounts of 3HD. Mylar are the highest, teflon have a little, and PP have like none.
 
You can also simply google "quantum materials." Yes, I'm sure that book will reveal the mysteries of our Universe. I have a physics degree BTW.

Edit: nezbleu realized his post was nonsensical and deleted it, so now mine doesn't make sense. Or does it? He denied existence of quantum material.

I don't know Bybee personally, so all this military secret stuff, I really don't care about. It's not something that you or I will definitively know. But if you listened to the Bybees and did not hear a difference, that's perfectly fine.

If one capacitor results in better sound quality to me than another in my application,
then that's the capacitor that I'll use, if it is otherwise acceptable. Of course,
two equivalent versions of a component will differ in various details, since they
are not identical, and made in the same process on the same equipment. But,
we don't need to know everything, or make our own electronic parts like people
did a century ago. We can (and generally must) make decisions at a practical level.

Someone earlier in this thread said that all well made speakers,

Hang on a second I just posted a few days ago that different speakers were obvious to me from 15yr old memories of what different design philosophies were.

This is far different from wire directionality, etc. What is a quantum material and how do I tell one, your comment sounds grounded in the pop physics that pollutes the web these days. Headline, lab experiment on 100 atoms of such and such carried out at 4 degrees Kelvin and 10 Teslas of magnetic field might soon lead to a revolutionary new battery technology.

For starters, isn't something like graphene a quantum material? Bybee cocoon needs to be tested to see what it's made of. Otherwise the mystery will remain.

Maybe it's made out of semimetal, like the T-1000?

Looking toward science fiction is a good start.

The net effect is that quantum slipstream technology far exceeds the speeds capable with a normal warp drive, and rivals the Borg transwarp technology. Transwarp isn't a specific type of drive, but a class of propulsion technologies that exceed the normal warp limits.
 
Do-you buy your photo lenses just reading their MTF ?

Eyes only of course, just like you buy an eyepiece for a telescope (I don't do photography). I have to admit it involves peeking. Why do you insinuate asking for an ears only test is the same as making a bunch of measurements and insisting that they determine what sounds better?

For that matter why is amateur astronomy so different from audio, male dominated hobby full of geeks but it more clearly comes down to the money and real performance. No one sells bags of magic pebbles to tie to your focuser to make the images "come alive".
 
Yes. Everything sounds the same. We can all go do something else now. It's all been done.

LR4 is the laziest of all, those acoustic slopes practically form themselves, with just one or two parts in the crossover with modern drivers. You have to use asymmetrical slopes for a flat baffle. There's virtually nothing time aligned or coherent about them. But it's something that anyone can do in their sleep so it's everywhere. $20 Dayton mic, free modeling software, and you're good to go!

I can only conclude you have no clue about what you are talking about.
