Brilliant Pebbles, a new tweak, cheaper than high end cables.

The Cable Co. and Geek Tweek have nice return polices when trying the more esoteric side of our hobby.  Results can vary depending on your understanding as to how to use them, and the resolving abilities of your room/equipment.

Actually, I cannot think of anyone who doesn’t have nice policies for returning esoteric audiophile products that don’t work out for some reason or another with the exception of some, but not all, aftermarket fuse companies. 

I roll my eyes when Quantum Physics is used to justify specific audio (or other technical advances).  Yes, the transistor was wholly invented by applying QP principles, but that's why there has never been a nearly complete, in-depth understanding of how those principles play out in real time.  It requires an incredible (the right word) expenditure of resources, time, effort & energy to achieve the most minuscule, noncommercial results leveraging QP i.e. Quantum Computing.  What's been achieved there is not scaleable & only in conditions hundreds of degrees below zero. Some very qualified people think these challenges will be overcome in the fullness of time (with no ETA on the horizon). You can prove experimentally, what there isn't with it far more easily.  Such as there is no time or space (in the Quantum realm & in ways our senses can't confirm directly in ours). Also that everything is a particle & a wave simultaneously & more still (what Einstein called spooky science he was uncomfortable with) that directly contradicts conventional physics.

We know it affects our realm (bubble chambers & the transistor affirm) but cannot easily prove it does in our specific inventions. This leaves every kind of room for would be backyard inventors & discoverers to claim just about anything. Trust your ears & leave the QP theorizing to those enjoying imaginatively worked out theories.  It's well to remember too, nothing new has been invented since the laser in the 60s & the pace of all fundamental scientific discovery has dramatically slowed everywhere. Except for the biological sciences, but that's another story altogether.

Just a note to say what Einstein was referring to by the word “spooky” was not wave particle duality but “action at a distance.” “Spooky action at a distance” (relativistic Physics) was the subject of the famous EPR paper in 1935. Everybody was pretty much already on board the wave particle duality train 🚂 once the double slit experiment for light was performed by Young in 1801, later confirmed for other particles in 1927.

But more to the point, I personally don’t use quantum physics to explain Brilliant Pebbles. It’s pretty straightforward atomic physics.

Even though I'm ignorant about such things QP, I will say... well said Mr. John1, I had to be reminded that molecules don't move (another well said by Mr. Tobor), charge does... Hmmm, ever been shocked?
I like the part though about 'trust your ears'.
If it gets the endorphins going... you're on to something!
