There are some real scientific explanations for the effect of piezoelectrics on electrical fields. That would mean on or very near to terminations, cables, power supplies, components. So some of Geoff's crystals on those places may indeed have been ahead of their time in the audio world - maybe, depending upon what crystalline structures he is using.
What explanation can you offer for crystals in a jar placed away from these?
I think that's the difference here. I'm not impugning Geoff nor am I familiar from actual experience with more than one of his products - and I'm not interested in a flaming debate!
Just a thought on why some things work, though they aren't familiar to all, and why some things probably don't, though by now everyone in the US has heard about "crystal power" for decades... YMMV

The answer is very simple for the crystals placed away from the equipment and cables, etc. - i.e., out in the room. The crystals operate as energy absorbers, reduce the unwanted effects of standing waves, early reflections, and vibration. Especially, but not exclusively, in room corners. The theory that crystals must be near an electrical source is incorrect. Even when the crystals are used on cables or in equipment the electricty/electromagnetism theory is incorrect.

You said:

You are speaking here of mechanical vibration in the air mass. Of course they are impacted by vibes in the room and piezoelectric materials characteristically generate an electrical field as a response to mechanical pressure. They convert one to the other in both directions. They have a big enough impact by converting from electrical field energy to mechanical energy on the sound when close to the source. But the impact in the way you describe is infinitesimal, to my way of thinking.
YOu also say:

Then you are operating from some theory that I've not run across, Geoff. The impact of the electrical field falls off proportionately to the distance from the source of those fields. To convert the electro=magnetic to the mechanical would require some proximity to the elecrto-magnetic source to be effective.
I'll admit that my physics is rather old (or I'm old and my knowledge is outdated), but I don't think the universe has changed that much!!! LOL
You studied physics of crystal structures in school? Interesting....my undergrad thesis involved bombarding magnetized metal crystals with high speed ions. What was yours?
