Sebrof, the problem with your argument is that it applies to almost everything we audiophiles do to improve our systems. "I tried a new speaker/amp/preamp/DAC/speaker cable/interconnect/power cord/what-have-you and it made my system sound better/worse." At some point we have to trust our perceptions.
I'll grant that the crystals sound loopy, but so do about 90% of the tweaks I've seen advocated here and elsewhere. As a natural skeptic who has entered the audiophile world, I've had to learn to withhold judgment on a lot of claims that seem both unlikely and exaggerated.
That said, I'm not buying any Amethyst crystals until I see a lot more "evidence" of their positive effects.
