Anyone Using Crystals?

crystals work great in your graphene connector goo!!!

I use it on my pet unicorn!

@geoffkait, @lak or anyone else who might know the answer to this safe operation type of question please. I have a piece of unshielded tourmaline sitting inside my DAC on the PCB right on top of what is a live conductor strip that is connected to what I believe is the voltage regulator of the DAC. So I guess this is not the DAC PCB. I have the tourmaline held down on the PCB on its edges with some blu-tack. The tourmaline piece actually straddles a couple of potentially live conducting metal strips. Do you think this is unsafe or could potentially damage my DAC? I did this because I believe that tourmaline is essentially non-conductive. And more importantly I believe that electricity (just as heat too) causes it to discharge ions in the way that is helpful. What I can definitively say is that the effect on my DAC’s sound quality is very nice indeed. Well worth my while leaving this way so long as it is safe. Your help/ideas as to safety etc. much appreciated. Thanks.

Inside a DAC, on of my favorite topics.
Back long ago in a small column of comments from Europe, A fellow mentioned stuffing digital gear with antistatic foam.
I read it at the time and promptly stuffed my DAC. Better sound, forever.
Anyway I STILL use another better version of that brand of DAC stuffed with foam.
The main thing is keeping the conductive material insulated. As for heat, the DAC is no warmer than before. and is on 24/7
I suppose one COULD use crystals for the same effect. To soak up the stray RFI from the chips, and reducing internal digital grunge.
Even if a stone is not fully conductive, I would keep it OFF live signal lines to be safe. Even a thin piece of Teflon plumbers tape. Or a bit of packing tape stuck to the underside of the stone...

OK thank you Elizabeth.  I will do that.

Generally speaking crystals are not conductive. That is not to say that some crystals, not all, exhibit electrical properties such as the Pyroelectric Effect or Peizoelectric Effect. Most, not all places where crystals are effective in audio systems turn out to be non electrical anyway, you know, like on top of CD players, speaker cabinets, room corners, where crystals’ resonance control properties come into play. In many cases, such as inside electronics and on wall outlets, to name two, it’s their anti resonant properties at play as opposed to anti RFI properties.
