"For reasons still unclear to me, it may take a few weeks (perhaps as much as 4 weeks) to sound good."
It's possible I suppose that the crystal structure of amethyst or other minerals in crystalline form might effectively limit or disrupt EM field emissions from power cords which can have the effects claimed.
If so, I would expect immediate results assuming everything is set up effectively from the start.
A 4 week delay in noticing results would seem to make it difficult to associate cause and effect with certainty though.
