Anyone Using Crystals?

I used black tourmaline that I bought on eBay from the seller worldincensestore. He has both glossy black tourmaline rods and rough black rocks. I have both but can’t tell the difference sound wise anyway. Bits of the rough black rocks are easier to crumble, and you might find some small amount of powder in your shipment due to impact in transit.

I am finding the biggest impact of using black tourmaline around the fuse box. The effect is on naturalness and coherence overall, and bass and mid-range. I was surprised by the sharply different effect I got from a piece of red agate in treble output around the fuse box, and am now very happy with a combo of the tourmaline and agate there. And then I have tourmaline rocks now sitting on most of my AC cable ends and in total they have a nice impact. As noted above by others placement does seem to matter. I want to try the tourmaline inside my balanced power transformer conditioners next, maybe next weekend.

I use pure black Tourmaline crystals for my Tourmaline Gun. Which is the reincarnation of Brian Kyle’s Tourmaline Gun. Of course Tourmaline is a well known pyroelectric crystal and produces negative ions when heated. It’s rather unlikely tourmaline’s pyroelectric property would be present or activated, whatever when applied to a RCA Jack or connector. Obviously all unused RCA jacks should be covered with something, Cardas Caps or whatever. I also am the proud inventor of using crystals on interconnect connectors and many other locations around the room. Brilliant Pebbles is what, almost 15 years old? Time flies when you’re having fun. 😛

Black Tourmaline has many uses that many would find hard to believe.
I'll just leave it at that.
