Here in the Sedona area some twirl crystals around the object of attention, but you could just as well get some temporary audio catharsis by draining your bank account and imagining you hear a difference with expensive tweaks. There was a fellow on the 'gon who claims that under a dollar a piece Artgum erasers as footers under his components worked as well or better than the audio-specific footers he had. Seems many audiophiles ask questions that suggest they need positive reinforcement to spend more money, when in the final analysis it's all up to individual subjectivity anyway. Human nature, always fascinating.
