Guys what you thinks about super-expensive capacitor like Duelund
Worth it or are a snake oil ?
An externally hosted image should be here but it was not working when we last tested it.
In my opinion snake oil. we never get to see any DBT or SBT comparing capacitors to hold up people's claims of hearing a difference. Till then, we should consider all pricey caps as overkill and a waste of money.

Yes, indeed, a snake oil merchant of the first water and a favorite of cranks. I'm surprised he hasn't added audio to his portfolio, joining the perpetual motion stuff.
I try to remain very open minded, but I am not willing to waste the money to find out that Duelund it performs and sounds no better than a $1 Axon film capacitor. I have used Mundorf, and in my own opinion they are little different than several modern electrolytic capacitors that have been arranged in parallel to attain the same value, and a low equivalent series resistance.

MundoRf are affordable even here in Argentina, but those Duelund cost over U$D350 each 😱
A resistor made this way does not cost 50 cents. Besides it 'might' do other things than just be a resistor.
Such as? Or is this just more emptiness from you?

Something newer on quantum resistance, 2007.
John can google!
So we have moved from alleged 'near-superconductors' to alleged nanotubes. Let's just assume for a moment of madness that one of these techniques has been employed inside a Bybee. That just makes it a very expensive way to make a low value resistor. Electrons outside the magic space will get scattered randomly as they always are so any effect will persist for about the distance of the mean free path. I don't know off the top of my head what that is for electrons in copper, and I can't be bothered to Google it, but I do know it is very small. Even if it does 'smooth' the current, that still leaves the tiny problem of distinguishing between incoming noise and incoming signal. Now if you could find us a peer-reviewed paper giving a plausible mechanism for a Maxwell demon we might stop pointing and laughing and begin to sit up and take notice.john curl said:A resistor made this way does not cost 50 cents.

It is unclear to me whether John is guessing or randomly blowing smoke into our eyes, knowing that non-scientists might be unable to distinguish fact from wild fantasy.

In either case, absolutely beautiful.

Look on the bright side, Steve, at least he didn't scan pages out of an introductory solid state physics textbook and pretend that there was something relevant to audio. That's progress.
This is actually very educational. We're seeing a perfect demonstration on how snake oil is extracted, refined, and sold.
Point taken.

Not mutually exclusive.

At 300 K, it is 3 x 10-6 cm.
At 4 K, it is .3 cm.
6 and 7 nines aluminum and copper can be as high as 10 cm below 4 K.

Annealing would certainly have an effect on that, no?

Yup.
We used aluminum, and it was unbelievably malleable out of the package. We had to make sure we didn't work harden it.

So the Bybee might work quite well in an especially cold music room?jneutron said:6 and 7 nines aluminum and copper can be as high as 10 cm below 4 K.
Hey, at least he did his work at a Lab. JLN labs.. by Jean-Louis Naudin . what a funny coincidence, he has the same initials...do wonders ever cease?
Lab in this context is generous, I finally got to see Jean-Louis on TV demonstrating his gravity "cancelling" lifters. These guys just don't get corona wind.
Same guy that has plans for a cubic meter vacuum chamber made with 6 pieces of 1/4" plexiglass.
Ah, that explains why I was thinking of a wedge of lime..Lab in this context is generous, I finally got to see Jean-Louis on TV demonstrating his gravity "cancelling" lifters. These guys just don't get corona wind.

Hey, that'll work perfectly well. Just make sure that it is inside another larger vacuum chamber so that there's never a inside/outside differential.
Perhaps by cubic meter, he meant 1cm by 1cm by a kilometer..
