As a layman who has a rudimentary understanding of physics I have to say I am skeptical.
Rearranging matter on a molecular level is a time consuming and expensive endeavor. So even if these do exist the cost would not in in the hundreds but hundreds of thousands of dollars. I mean they are just figuring out what to do with buckyballs and how long did it take to figure out what to do with super conductivity, I think that's what they use for maglev trains.
The ear hears what it wants to sometimes as does all your senses, proven fact. When I talk about the different caps in an amp for instance I talk more about how the guitar and amp responds to my playing first so it's totally a feel thing first and foremost. And I must add before I did my test I was skeptical and thought it was BS, until I tested all those caps. But this just goes beyond anything anybody can substantiate or test really so they can say what they want to.
But I will say this, since my cable company went to fiber optics and all digital the sound and picture quality have gone DOWN not gotten better. Same for the TVs themselves, even though it cost 3 grand for the POS. I drove around the guys in the 1980s who had to fix all the fiber optics connections that were done wrong. It ran from New Jersey to all the tunnels and bridges to the Dish center here on Staten Island, to the World Trade Center, empire state building, to Brooklyn and beyond.
Looking at the items themselves it looks like someone made them in their basement. When you start talking about Quantum physics and electricity/electronics it rules out your basement unless you are Tesla himself or the second coming....

Some of the the sound of an instrument is noise. Part of what makes a Stratocaster what it is tone wise is the noise of those single coil pickups. People who have tried to eliminate the noise of those guitars have also eliminated the tone. Music is partly made up of noise.
