Sebrof, as I said, I'm a natural skeptic. But I'm experienced enough to know that I don't know everything about how everything works. Google "qx4 stereophile" and read about a completely nonsensical device that apparently works. Then search on "quantum qx4" in the forums here. It doesn't make a lot of sense, but the results are apparently reliably reproducible.
So, crystals? Sure, why not?
