Anyone Using Crystals?

OK, so I got 'overamped', But...any effect crystals might have would be very localized, as in the crystals themselves.  They won't act like a sponge in a larger volume.
RF is an electron excitation....photons are light 'carriers'.  If we could 'see' RF, right now you'd be in a very dense fog considering all the signals we humans create these days....
I'm a pretty diehard skeptic when it comes to when it comes to claims of 'this, that, and the other' made from or for various things touted to us as a interest group and in the general marketplace.  'Snake Oil' is still a popular product....it's just wrapped in a different package.  It still is designed to transfer $ from one hand to another...;)
...and I'm still in the shallow end of my pool when it comes to being 'cranky' about 'things', and the claims about such....

If we're talking about crystals, the obvious mechanism would be fairies. Or wood sprites.. they juggle the photons. Don't you guys know anything?!

Crystals are useless. OTOH, if you acquire the dodo bird beak your system will sound like never before🐧✌️

These AA threads on crystals linked below go back even further than the ones Sabai posted. I came out with Brilliant Pebbles in 2003 at the London HiFi Show. They had already been around for a few years. A good time was had by all. Well, maybe not all. 😀

Hi-Fi News Show, London, Sept 2003 -- Audiopax/Ecosse/Meitner exhibit coordinator (Precious Music, Scotland): "Now, if I say that dozens of people said we had the best sound at show, many others said we had the best sound they had ever heard, many dealers, competitors and reviewers came round to check out the room and in particular the Audiopax Amp and Meitner dac...well you can imagine we felt pretty pleased with our efforts." (4 Brilliant Pebbles were used in this room -- one on each Audiopax speaker and two in room corners.)
