Not to take anything away from your excellent summary, don't forget it will radiate heat energy from I^2.R losses.
Ah, so that is how it works!

They just mean the new dac is a quantum improvement over their last dac design.
Given the size of Planck's constant that means an incredibly tiny improvement.

Seems that I've missed that, but nevertheless RNMarsh's post (yesterday starting this subsubtopic) was about filtering (maybe) at higher frequencies (end of audioband and above).......
If you think about the alleged filtering action added to a potential divider consisting of a piece of wire+Bybee feeding a typical audio equipment impedance (say 10k-100k?) then it should not take you long to work out that any filtering (even if real) is so hopelessly small that only people with real Golden Ears will hear it and even then only when they know the device is present.
 
A good deal of misinformation is being put up here about Jack Bybee, his devices and me.

Let's correct this: First, Scott must be referring to an experimental Bybee device (never on the market) that I heard (with and without) at Bybee's house some years ago. I do have a set of these devices myself, but I have never put them in my system. They do NOT filter rumble. More like low frequency noise from the record. Jack just told me that they were too expensive ( the primary parts) to make into something salable. You see, Jack does NOT make the active devices, himself. He buys them from a confidential source, and until recently always has.
The 'goop' impregnated foil that Scott took apart is completely separate, and apparently Jack sources the active substance and then finds ways of applying it to things, a bit like Dan appears to do. I have seen the raw materials, they are like a dark sand or something. This works on an an entirely different principle than his original devices.

The original Bybee devices are supposed to be a 1/f noise sort of filter, by changing the state of some electrons that are prone to make 1/f noise, apparently.

The newer devices tend to change the air by resonating with one of its major components, making the air 'different'. Works for me in both my digital and even my new power amplifier, and how!
The hi fi show was pretty sad, and I left after a few hours. Found a number of audio friends there, however. It was worth that.

Both complete nonsense, pretty sad indeed. There is nothing more here than Geoff Kait's teleportation tweek where you pay him to play noise at your system over the phone. I'll do that at 1/2 price, and I have better noise.
 
Many years ago, Jack tried Geoff Kait's 'disk' and could not find anything to make it work with his system. I, too, am more suspect of Geoff Kait than I was originally. I never could be sure of him. We used to talk by phone, years ago, but not in recent years. I am also suspicious of his telephone tweak, I prefer to keep an open mind about things that I have never tried.
 
We can all be fooled. I was probably 'fooled' when I first tried Geoff Kaits Chip (disc), many years ago. But a false positive sometimes is better than all the false negatives that you guys insist on.

Bonsai, if you wrote that thing about Jack Bybee, then you are a liar.
