Do you find that Tourmaline powder is more effective than small granules like sand? Or tiny chips?
stuff like sand sized works also quite well, i bet you could actually use (quartz) sand to a satisfiying degree, but yea powder seems somewhat more effective, tho i still wonder wether this comes from the particles all having the same size vs some varried sizes
i bought mostly 0,5mm - 3mm now... i might end up grinding it myself further down
i will probably doublecheck here myself
One can also snip off the positive contact pole from the inside. Then coat with epoxy or similar, so does not make contact with positive contact. I have to ponder this a bit and try it.
well pulling the signal pin is just my OCD kicking in to completely eliminate any possible effect on the signal itself
but your way is maybe worth a shot too with isolated pin, a electromagnetic field could/will still form.... i might compare this, thanks for the thought
No idea at this point if both contacts vs ground only changes what is heard.
i just tested this 2-3 days ago as the last test was a while ago and utilized plus pole definitely is more audible, but something sound perception wise tells me that this is "too much" and not only a positive effect... but please test and let me know what you think
most people just solder a piece of 1,5mm2 solid wire onto the plus pin extending it a few centimeters to the end of the plug (without making a short
) ... i tried 3x 1.5mm2 twisted together and also this.. is even more audible, tho like i said, you run into the danger of this theoretical capacitor effect that might just change the sound a bit more, like using a different cable with different capacitance
Edit: oh i think i missunderstood your post, no there are a few things at play i think... thats why experimenting is key here
i havent build much rca caps so far, maybe 10-15, because with no further incentive i was just happy with the effect i got with rather simple methods but i will some further testing here too
but obvious things are:
1. plus pole utilized
2. connector completely shielded
3. crystal size
4. which crystal
5. ground surface area extended or not
6. glue (which i havent thought about before "critically")
7. materials of connector and with which materials you extend the ground surface
atleast these are the somewhat objective factors...
