That's just for laughs, though. But I guess a true hifi nut could get them. The product text is fantastic: "What the heck is it? Brilliant Pebbles is a unique and comprehensive system for tuning the room and audio system based on special physical properties of highly symmetrical crystal structures. Brilliant Pebbles has been evolving since its introduction 6 years ago at the London HI Fi Show, especially the number of applications, many of which were discovered by our customers. Brilliant Pebbles addresses specific resonance control and RFI/EMI absorption problems associated with audio electronics, speakers and cables, as well as acoustic wave problems associated with the listening room boundaries and the 3-dimensional space within the boundaries. Brilliant Pebbles comprises a number of precious and semi-precious stones (crystals) selected for their effectiveness. The original glass bottles for Brilliant Pebbles have been replaced by clear zip lock bags, which have a more linear response than glass. We employ a number of highly-specialized, proprietary techniques in the preparation/assembly of Brilliant Pebbles to enhance the crystals' inherent characteristics. The fundamental operating principle of Brilliant Pebbles involves a number of atomic mechanisms in the crystals. Brilliant Pebbles will enhance the performance of your audio system so your favorite music and even your experience playing online fantasy games will become a mind blowing auditory experience."
