I'm aware that some of the piezoelectric substances do indeed have this filtering effect and am going to experiment with them next. How did you determine how much to use and where? Trial and error?

You could do a search on this forum under quartz, tourmaline or topaz and get some ideas. I've had good luck on top of components, power inlets, transformers, near tubes, near speakers--just about anywhere. Here are pictures of my preamp and phono pre with tourmaline and topaz inside:
And here is an image of my breaker box:
All of these crystals made a very noticeable improvement, but I've taken the black tourmaline out of the preamps and didn't notice any change.

... are they just sitting there or have you glued/taped/fixed them in some way?
I used silicone which remains flexible after it has set. According to unclestu52, providing some flexibility to the crystal mount is necessary to convert the electromagnetic energy into mechanical vibration. See the link below for his explanation. If you look for his posts on crystals, you can find a lot of information on the physics of crystals along with his speculations and experiences.
bleep
It looks like more people are finally catching on to what Machina Dynamica( Brilliant Pebbles) has been using for quite some time. (o:
Yes, trial and error is all you can hope for when experimenting with various crystals, etc. Too much can over-dampen and strangle the music.
Looks like we can find a space to agree out here in the Outer Limits where EVERYONE back at WC thinks we're nuts!
;-)
Yes,
I have known of the virtues of crystalline structures regarding things audio since the Brilliant Pebbles were introduced. All the while, the naysayers put poor Geoffkait through Hell, slamming his Brilliant Pebbles. (o:
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:
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.
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?

Yep, been using Topaz in Brilliant Pebbles for 7 (count 'em) years. Among other crystal types. Power to the pebble.
